===== Firearm Accessories =====

Shooters love gizmos! Below are dozens of accompaniments
and add-ons for guns. Should statistics for such a
device appear in a firearm description, they take precedence
over these generic rules. The GM may make similar
gadgets available for crossbows, liquid projectors, etc.,
where logical.

==== HOLSTERS, SCABBARDS, AND SLINGS ====

Before the 1850s (mid-TL5), holsters were an item of
horse furniture, not of human dress – cavalrymen slung a
pair across the saddle pommel. Handguns were typically
carried in a pocket or thrust through the belt. Large pistols,
notably those issued by England’s Royal Navy and carried
by Highland infantry, had flat spring hooks on one side to
hold them in the belt. For a romp on Saturday night, cowboys
tucked their Colt revolvers under their shirt, with the
loading gate open; this prevented the gun from slipping any
lower and facilitated a fast draw, if needed. Small pistols fit
neatly in the side or tail pocket of a gentleman’s coat, or in
a lady’s muff. They could even be tucked into the crown of
a hat – a courtly doffing of the hat might be an assassin
drawing his weapon!

Holsters and scabbards protect firearms from the elements,
help get them into action more quickly, and prevent
them from being dropped or lost. Each model of gun
requires its own specific holster or scabbard. Similar
weapons may fit, at the GM’s discretion.

Getting a pistol into or out of a holster takes one Ready
maneuver. A successful Fast-Draw (Pistol) roll lets you
draw a handgun as a free action; see Fast-Draw (p. 81). The
Quick-Sheathe perk (p. 252) allows you to holster a weapon
the same way.

Unslinging or slinging a long arm takes two Ready
maneuvers – or three, if the slung position is on the back.
For unslinging, a successful Fast-Draw (Long Arm) roll
reduces these times by a second. The Quick-Sheathe perk
extends the benefits of Fast-Draw to slinging a weapon.
For those trying to maintain a low profile while packing
heat, holster design and placement can greatly affect the
Holdout skill. The best hiding places are the hardest to
reach. A gunman must choose between getting to his gun
quickly and keeping it out of sight.

=== Belt Holster (TL5) ===

This is the standard hip holster worn by cowpokes, soldiers,
and cops from the mid-1800s to present. On early
versions, a leather loop around the hammer keeps the
weapon from falling out. It takes a Ready maneuver to
remove this and enable use of Fast-Draw (Pistol). From the
1920s, a thumb-break strap – so-called because the gunman
thumbs open the closed strap as he draws – serves the same
purpose but is always ready for a speedy draw. $25, 0.5 lb.
LC4.


===Lanyard (TL5)===
A lanyard is a cord running from a weapon to the belt or
neck. It lets a gunman retrieve a dropped gun on a DX roll.
Each attempt requires a Ready maneuver. Most firearms
used with Guns (Pistol), but few others, have a ring for
attaching a lanyard; see the weapon tables for exceptions. A
lanyard can be cut: -6 to hit, DR 2, HP 2. $1, neg. LC4.
===Military Holster (TL5)===
Military holsters often have a flap designed to keep dust,
mud, and crud off a handgun; the pistol isn’t “exposed” for
the purpose of Slime, Sand, and Equipment Failure
(p. B485) and may avoid the Malf. penalty for harsh environments
noted in Cleaning and Maintenance (p. 80). Such
holsters are slow, however. The flap can be opened and
tucked behind the belt to avoid the Fast-Draw penalty, but
then it provides no protection. Holsters like this often have
built-in magazine or cartridge pouches. -2 Fast-Draw
(Pistol). $50, 2 lbs. LC4.
===Rifle Sling (TL5)===
A sling allows a gunman to use both hands while keeping
his shoulder arm close. It also lets him brace even when
he has nothing to prop his gun on, giving an extra +1 when
aiming; see Aim (p. B364). Bracing with a sling is a twohanded
task that takes one Ready maneuver per -1 Bulk;
e.g., five seconds at Bulk -5. Leaving this position, thereby
freeing the hands, requires a Ready maneuver. Most
firearms used with Guns (LMG, Rifle, Shotgun, or SMG),
but few others, have swivels for fastening a sling; see the
weapon tables for exceptions. $10, 1 lb. LC4.
===Scabbard (TL5)===
This is a sheath or a covering for a carbine, shotgun, or
other shoulder arm. A scabbard is a common accessory
among those who ride animals, motorcycles, and opentopped
vehicles (for examples, see WWII Jeep, pp. 236-237).
It protects a long arm in the same way that a military holster
(see above) protects a handgun. $25, 1 lb. LC4.
===Shoulder Holster (TL5)===
A shoulder holster is worn on the off-hand side, usually
under the armpit. Some models carry the gun horizontally;
others hold it vertically, barrel-down or (rarely) barrel-up.
Most have provision for speedloaders, magazines, or handcuffs
under the opposite armpit. This is more comfortable,
as it helps balance the rig. Shoulder holsters are a common
choice for private eyes, police detectives, aviators, and AFV
crew. -1 Fast-Draw (Pistol). $50, 1 lb. LC4.

=== Sleeve Holster (TL6) ===

This is a spring-loaded holster strapped to the forearm
in the tradition of James West in The Wild, Wild West or
Travis Bickle in Taxi Driver. The wearer activates it via a
lever near the elbow, typically by pressing the elbow
against the body. This requires a Fast-Draw (Pistol) roll.

Success causes a slim metal bar to thrust forward, allowing
the gunman to grasp the handgun (no larger than Bulk -1)
mounted at the end. Failure means the device fails to work
properly; getting the weapon requires use of the free hand
and a further Ready maneuver. Critical failure indicates
the device breaks – extracting the gun requires 2d seconds
of prying and pulling with the free hand! -2 Holdout. $500,
0.5 lb. LC4.

=== Fast-Draw Rig (TL7) ===

A holster and belt can be custom-built for speed. The
drop-hip belt with its low-slung, smooth-drawing, steellined
holster is a 1950s Hollywood novelty; authentic Old
West gunfighters never used it. Nevertheless, it is fast! +2
Fast-Draw (Pistol). $500, 3 lbs. LC4.

=== Patrol Sling (TL7) ===

This padded sling lets the wearer safely drop his long
arm without pausing to stow it, immediately freeing both
hands for another task. It’s adjustable: at rest, the weapon
hangs either horizontally, at waist level, or vertically, typically
with its stock near the armpit and its barrel pointing
down and behind the hip so that it doesn’t hinder its owner
as he runs. The gun can be fired without unslinging it.

Raising it to a shooting position requires only one Ready
maneuver; a successful Fast-Draw (Long Arm) roll makes
this a free action. Most firearms used with Guns (LMG,
Rifle, Shotgun, or SMG), but few others, have swivels for
fastening a sling; see the weapon tables for exceptions. +1
Fast-Draw (Long Arm). $50, 2 lbs. LC4.

=== Undercover Holster (TL7) ===

Concealable holsters are padded, designed to soften the
hard edges of a hidden handgun. Most are worn inside the
pants, with a shirt over the top of the gun (Bulk -2 or
worse), or on the ankle (Bulk -1 or 0 only). -1 Fast-Draw
(Pistol), +1 Holdout. $125, 1 lb. LC4.

=== Retention Holster (TL8) ===

Modern hip holsters, especially those used by police, are
sometimes designed to prevent an assailant from snatching
the holstered sidearm. Without a specific twist or tilt, the
pistol won’t come out of such a holster, even if it’s turned
upside down. This makes it difficult for anyone but the
wearer to draw the gun. The owner gets +2 to his Retain
Weapon technique (p. B232) while his weapon is holstered.
$100, 0.5 lb. LC4.

==== MAGAZINE MODIFICATIONS AND RELOADING AIDS ====

Several innovations exist to increase ammo capacity
and/or cut reloading time for cartridge-firing repeaters. For
the costs and weights of standard magazines, spare cylinders,
and so on, see the weapon tables and descriptions.

=== Extended Magazines (TL6) ===

Extending the length of a detachable magazine gives
more ammunition capacity – typically 1.5¥ to 2¥ normal.
Extended magazines are heavier, possibly unreliable (-1
Malf., at the GM’s discretion), and often unwieldy (add -1 to
weapon’s Bulk if capacity is over 1.5¥ normal). Some even
protrude downward far enough to make shooting while
prone difficult or impossible.

Example: Replacing the 20-round magazine of an
M16A1 rifle with a 30-round magazine doesn’t change
Bulk. Swapping the 17-round magazine of a Glock 17 pistol
for a 31-rounder adds -1 Bulk.

Drum magazines (TL6) stow extra ammo more compactly
than normal extended magazines; they’re essentially
extended magazines coiled to reduce length. Drums don’t
protrude any more than standard magazines, but they do
worsen Bulk (add -1 to Bulk if capacity is above 3¥ normal).
They’re also heavy, expensive, and almost always less reliable
(-1 Malf. or worse).

High-density magazines (TL7) are available for some
weapons. These increase capacity without increasing magazine
length, typically by stacking cartridges in several staggered
rows. They’re heavy, but don’t affect Bulk. Some are
unreliable (-1 Malf., at the GM’s discretion). High-density
magazines aren’t an option for weapons that insert the
magazine in the grip – like most pistols and some SMGs –
unless part of the original design.

To find the weight of a loaded magazine, multiply weight
per shot (WPS) from the Ammunition Tables (pp. 175-177)
by the number of rounds it holds, and then by a fixed multiplier:
1.1 for a high-density alloy or plastic box; 1.2 for an
extended alloy or plastic box; 1.3 for a high-density steel
box, or an alloy or plastic helical drum; 1.5 for an extended
steel box; 1.6 for a helical steel drum, or an alloy or plastic
drum; or 2 for a steel drum.

Example: The M16 fires the .223 Remington round
(WPS 0.026). An extended 50-round magazine made of aluminum
alloy would weigh 0.026 ¥ 50 ¥ 1.2 = 1.56 lbs.,
rounded to 1.6 lbs.

To find the cost of an empty magazine, multiply WPS by
five times the number of rounds it holds, and then add a
fixed cost factor: $25 for an extended steel box; $27 for a
high-density steel box; $30 for an extended alloy or plastic
box; $33 for a high-density alloy or plastic box; $250 for a
steel drum/helical drum; or $300 for an alloy or plastic
drum/helical drum.

Example: The extended 50-round alloy magazine above
would cost (0.026 ¥ 5 ¥ 50) + 30 = $36.50, empty.
These costs and weights are generic. Historical magazines
often differ. See the weapon descriptions for many examples.

Normally, the gun’s manufacturer produces extended
magazines as accessories. Gunsmiths can make them, however.
This requires two Armoury (Small Arms) rolls: one to
design the magazine, one to build it. Note that in some real-world
jurisdictions, high-capacity magazines render LC3-4
guns LC1-2.

=== Speedloaders (TL6) ===

A speedloader lets a gunman with a revolver insert all – or
at least several – rounds into his weapon’s cylinder simultaneously
instead of reloading a cartridge at a time. This dramatically
reduces reloading time; see Reloading Your Gun (p. 86).
Speedloaders only work for revolvers that break or tip open,
or those with swing-out cylinders; gate-loaders can’t use
them. One of the first models was the Prideaux speedloader
for Webley revolvers, introduced in the 1880s. Speedloaders
for swing-out revolvers weren’t widely used until the 1960s.
$10, 0.1 lb. LC4.

=== Clamped Magazines (TL8) ===

Magazines can be clamped side-by-side using a removable
bracket ($20, 0.3 lb., LC4). Some plastic magazines have integral
studs and brackets that let shooters clip as many magazines
as desired alongside one another. Both developments
are TL8, but taping magazines together with duct tape (p. 26)
has been a popular field modification in every war since
WWII. Any of these measures saves one Ready maneuver
when reloading; see Reloading Your Gun (p. 86). Magazines
not in use are prone to get dirt inside, and taped magazines,
where one points down, often get damaged feeding lips; the
GM may assess -1 Malf. in suitably harsh conditions.

==== SIGHTS AND AIMING AIDS ====

Guns are often given targeting systems – sights, scopes,
even computers. The combined bonus from all such gadgetry
can’t exceed the weapon’s base Accuracy (but see Precision
Aiming, p. 84). For instance, a telescopic sight that gives up to
+4 Acc gives only +2 Acc on an Acc 2 pistol.

=== Telescopic Sights (TL5) ===

Telescopic sights, or “scopes,” for firearms are a late-TL5
development that becomes common at TL6-8. A scope gives
a bonus to hit if you take one or more Aim maneuvers: +1 Acc
per full doubling of magnification. With a fixed-power scope,
you must Aim for at least as many seconds as the bonus. With
a variable-power scope, you may Aim for fewer seconds but
this reduces the bonus by a like amount. Variables cost more
and are somewhat more fragile. All scopes listed in this book
are fixed-power unless noted otherwise.

Since they also collect light, all but the cheapest TL7-8
scopes remove -1 from darkness penalties. Some have an
illuminated reticle (lit by battery, tritium, etc.) to aid aiming
in low-light conditions; this cancels up to -2 in darkness
penalties. For other notes, see Optics (p. 47) and Scopes
(p. B412).

None of these benefits apply to unaimed shots. In fact, a
high-powered scope (anything over 4¥) makes unaimed
shots slower: add -1 to Bulk.
Fixed-Power Scope (TL5). An early device, 3-4’ long. Pick
any magnification between 2¥ and 32¥. $100 per +1 Acc, 3-
4 lbs. LC4.
Fixed-Power Scope (TL6). Pick any magnification
between 2¥ and 32¥. $125 per +1 Acc, 1.5 lbs. LC4.
Fixed-Power Scope (TL7). Pick any magnification
between 2¥ and 32¥. $150 per +1 Acc, 1 lb. LC4.
Variable-Power Scope (TL7). Pick three magnifications
between 1.5¥ and 32¥, typically whole-numbered multiples.
$200 per +1 Acc, 1.5 lbs. LC4.
Variable-Power Scope (TL8). Pick three magnifications
between 1.5¥ and 32¥, typically whole-numbered multiples.
$250 per +1 Acc, 1 lb. LC4.
Example: A TL7 fixed-power 4¥ scope gives +2 Acc and
costs $150 ¥ 2 = $300. A TL8 variable-power scope with 3¥,
6¥, and 9¥ (written 3-9¥) gives up to +3 Acc and costs $250
¥ 3 = $750.
Improved-Visibility Sights (TL6)
Making a gun’s sights more visible reduces the difficulty
of seeing them – and hence shooting – in the dark.
Improved-visibility sights typically have three dots or lines
of light-colored paint, or inserts of luminescent material
(often tritium). This negates -1 in darkness penalties, but
has no effect in normal light. (The GM may extend this benefit
to such simple makeshift measures as a white handkerchief
tied around the muzzle, common at lower TLs.)
Improved-visibility sights appear as optional accessories
for a few guns starting in mid-TL6, become integral fixtures
on some late-TL7 firearms, and are either standard or available
for nearly all TL8 weapons. $75, neg. LC4.
Collimating and Reflex Sights (TL7)
Invented in WWI – originally for aircraft use – these
sights involve a lens onto which a bright red or yellow dot
is projected, coinciding with the weapon’s point of aim out
to a certain range. In a collimating sight (often called a “red
dot sight”), the lens is incorporated into a scope-like tube.
In a reflex sight, the lens is mounted in a small frame
(known as a “head-up display,” or HUD, on aircraft).
Either type of sight improves situational awareness by
allowing the shooter to keep both eyes open. Target acquisition
is faster: instead of aligning fore and rear sights, the
gunman simply superimposes the dot on his target. This
gives +1 Guns skill at ranges up to 300 yards and makes it
easier to aim in low-light conditions, negating up to -3 in
darkness penalties on all shots. Both designs can be used
with night-vision devices but not with magnifying scopes.
Note that the dot is visible only through the lens – the
product of electronics or a tritium or battery illuminator.
These sights don’t project a visible dot on a distant target
like a targeting laser (pp. 156-157) does. If you have a sight
and a laser, you must choose to use one or the other – not
both at once.
Collimating Sight, Battery (TL7). $250, 0.5 lb., XS/250
hrs. LC4.
Collimating Sight, Tritium (TL7). An unpowered tritiumilluminated
version. $400, 0.5 lb. LC4.
Reflex Sight, Battery (TL8). $350, 0.25 lb., XS/500 hrs.
LC4.
Reflex Sight, Tritium (TL8). $550, 0.25 lb. LC4.
Night Sights (TL7)
Image-intensifying night sights (also known as “light
amplifiers” or “starlight scopes”) electronically amplify
ambient light. The higher the TL, the lighter and smaller
they get. Some include magnification, and work like telescopic
sights (pp. 155-156); others are add-ons, installed in
front of scopes or collimating sights (above). In all cases,
the shooter has Colorblindness (p. B127) and Tunnel Vision
(p. B151) while using the sight. For other important details,
see Night-Vision Optics (pp. 47-48).
Early Night Sight (TL7). Introduced in the 1940s, this
huge device gives Night Vision 2. It’s usually used with IR
illumination (p. 47). It adds -2 Bulk. $1,000, 4 lbs., external
power. LC3.
Night Sight (TL7). By the 1960s, a bulky but manportable
sight gives Night Vision 4 and +2 Acc. It adds -2
Bulk. $500, 5 lbs., 4¥S/30 hrs. LC3.
Improved Night Sight (TL7). A 1970s-era system gives
Night Vision 5 and +2 Acc. It adds only -1 Bulk. $1,500, 3.5
lbs., 2¥XS/60 hrs. LC3.
Improved Night Sight, Add-On (TL7). This gadget adds
Night Vision 5 to the benefits of another scope or sight.
$1,000, 2.5 lbs., 2¥XS/60 hrs. LC3.
Advanced Night Sight (TL8). From the 1980s, a typical
night sight gives Night Vision 7 and +2 Acc. $2,500, 2 lbs.,
2¥XS/90 hrs. LC3.
Advanced Night Sight, Add-On (TL8). This accessory
adds Night Vision 7 to the benefits of another scope or
sight. $1,500, 1 lb., 2¥XS/90 hrs. LC3.

=== Tactical Lights (TL7) ===

A powerful flashlight mounted on a firearm can illuminate
the area immediately in front of the muzzle. Poachers
at mid-TL6 jury-rig such things, but purpose-built tactical
lights are a mid-TL7 development that only enters wide use
at early TL8, with the appearance of halogen burners compact
enough to mount under pistol and SMG barrels. See
Tactical Lights (p. 52) for rules and statistics – small lights
are usual for pistols, large ones for shoulder arms. When
shooting at ranges within the listed beam length, either version
lets the gunman use the more favorable of -3 or the
actual darkness penalty (see Visibility, p. B394) and may
momentarily blind the target. Such lights can also accept
IR filters (see Flashlights, pp. 51-52).

=== Targeting Lasers (TL7) ===

Also called “laser sights” (p. B412), these devices are lowpowered
lasers that project an aiming dot onto the target.
Early versions were bulky gadgets cobbled together by amateurs
in the 1970s. Commercial versions were miniaturized
for sale in the 1980s. Models small enough to fit inside
some pistols appeared in the 1990s.
If you can see your targeting laser’s aiming dot, you get
+1 to hit whether or not you took an Aim maneuver. If your
target can see it, he gets +1 to Dodge – but the GM may
require a Fright Check! Activating the laser is a free action;
declare whether it’s on before you Aim or Attack. Targeting
lasers have a maximum effective range beyond which the
dot is too dispersed to give a bonus, however. If no range is
given, assume that it’s matched to the 1/2D range of the
weapon on which it’s mounted.
Beam color, which depends on wavelength, modifies
effective range in some situations. Red lasers are most common,
and work well in low-light conditions but suffer as
lighting improves (1/3 effective range in daylight). Orange
lasers perform better in daylight (1/2 effective range).
Green lasers have twice normal range in low light and normal
range in daylight. Infrared (IR) lasers always get full
range, but you need Night Vision, Infravision, or
Hyperspectral Vision to see them. At TL7, red is the only
option; at TL8, lasers can instead be orange (¥1.25 cost),
green (¥4 cost), or IR (¥1.5 cost). IR lasers are LC2.
Note that the laser beam – as opposed to the aiming dot
– is generally invisible. In smoke, fog, and similar conditions,
though, it’s easily seen, betraying the shooter’s position!
Green beams are always visible, while IR ones are
always invisible to those without special vision advantages.
A shooter can use a targeting laser simultaneously with
a telescopic sight (pp. 155-156) but not with a collimating
or reflex sight (p. 156). At TL8, a targeting laser and a tactical
light (above) can be combined into one accessory; add
costs but use only the heavier weight.
Primitive Targeting Laser (TL7). A large, first-generation
device with a 200-yard range. Adds -1 to Bulk. $1,500, 5
lbs., M/2 hrs. LC3.
Targeting Laser (Sidearm) (TL8). A compact targeting
laser with a 150-yard range. $150, 0.25 lb., 2¥XS/50 hrs.
LC3.
Targeting Laser (Shoulder Arm) (TL8). A compact targeting
laser with a 750-yard range. $750, 0.5 lb., 2¥XS/50 hrs.
LC3.
Integral Targeting Laser (Sidearm) (TL8). A miniature
targeting laser with a 150-yard range, installed inside the
grip sideplates or in place of the recoil spring rod. $450,
neg., 4¥T/2 hrs. LC3.
Integral Targeting Laser (Shoulder Arm) (TL8). A built-in
targeting laser with a 750-yard range. $900, neg., 2¥XS/100
hrs. LC3.
Computer Sights (TL8)
At TL8, full-solution fire-control systems with integral
ballistic computers are introduced for infantry weapons.
Initial platforms are rocket launchers and grenade launchers,
which profit greatly from improved rangefinding and
programming. As TL8 progresses, these sights grow small
enough to mount on small arms.
Typical devices run a targeting program that gives +1
Gunner or Guns, include a laser rangefinder, and incorporate
magnification (optical and/or electronic) and low-light
capability (image intensification or thermal imaging). The
gunner lases the target, and the computer calculates the
aiming point and shows it on an integral display. This provides
an extra +3 to hit that target with an aimed attack.
Computer Sight (TL8). Includes a targeting program (+1
Gunner/Guns), a laser rangefinder (+3 Acc out to 4,000
yards), 3-9¥ magnification (+1 to +3 Acc), and either Night
Vision 7 or Infravision. Adds -2 Bulk. $22,500 (with Night
Vision) or $30,000 (with Infravision), 10 lbs., M/30 hrs.
LC2.
Mini-Computer Sight (TL8). Includes a targeting program
(+1 Gunner/Guns), a laser rangefinder (+3 Acc out to
2,000 yards), 2-4¥ magnification (+1 to +2 Acc), and either
Night Vision 7 or Infravision. Adds -1 Bulk. $12,500 (with
Night Vision) or $20,000 (with Infravision), 2.5 lbs., 2¥S/2
hrs. LC2.
Thermal-Imaging Sights (TL8)
Electronic passive IR-imaging sights for nighttime target
acquisition have been available since the 1980s.
Shooters using such devices have Colorblindness (p. B127)
and Tunnel Vision (p. B151). See Thermographs (p. 48) for
other important details.
Thermal-Imaging Sight (TL8). Gives Infravision and +2
Acc, and adds -2 Bulk. $8,000, 5 lbs., M/5 hrs. LC3.
Improved Thermal-Imaging Sight (TL8). A lighter 1990sera
sight still gives Infravision and +2 Acc, but adds only -1
Bulk. $8,000, 4 lbs., M/10 hrs. LC3.
Advanced Thermal-Imaging Sight (TL8). By the 2000s,
these sights give Infravision and +2 Acc without affecting
Bulk. $10,000, 1 lb., 2¥S/2 hrs. LC3.

==== Sound Suppressors ====

The sound of a gun firing is the sonic boom of the supersonic
propellant gases and possibly the projectile. The
speed of sound at sea level is about 1,086 feet per second,
but the muzzle velocity of a 9¥19mm pistol round is
approximately 1,200 fps and that of a military rifle is 2,500-
3,500 fps – and powder gases travel at over 4,500 fps! A
sound suppressor, often called a “silencer,” confines and
slows gases and/or projectile before they leave the barrel,
reducing noise.
The Maxim Silent Firearms Co. introduced the first
commercially available suppressor in 1908; it was widely
used for indoor target shooting. Silencers generally
remained legal in the U.S. until the gangster and subversive
hysteria of the 1930s. After 1934, they were regulated: some
states banned private sale, while others required registration
and a $200 Federal tax.
Today, most countries outlaw suppressors. In some
noise-conscious European nations like Finland, though,
rifle (and even MG) suppressors are legal and sometimes
required for sport shooters. Military and espionage services
have easy access to silencers, of course, and an armorer or
a machinist can make one (see Home-Built Suppressors,
p. 159).
A suppressor doesn’t completely negate a firearm’s report
(but see Cinematic Silencers, p. 159) – it merely reduces the
range at which it’s heard and identifiably a gunshot. The
Hearing Distance Table gives the range at which an unsuppressed
shot is audible on an unmodified Hearing roll.
Hearing Distance Table
Sound: Weapon sound in question (other sounds included
for comparison).
dB(A): Decibel range at muzzle, weighted for human

listener is closer to the sound source, -1 per step by which
he’s more distant. For distances between two lines on
the table, use the higher of the two. A suppressor adds a
further penalty.
Example: A Walther PPK (a light pistol) is audible on an
unmodified Hearing roll at 256 yards. At 300 yards, the roll
is at -1. With a suppressor that gives -2 to Hearing, the roll
is at -3.
The listener’s location also matters. It’s harder to hear a
gunshot outside a cone in front of the gun’s muzzle.
Individuals located behind or far off to the side of the muzzle
have -1 to Hearing. The GM may apply other modifiers:
Background noise: -5 for busy street; -6 for blaring TV
set; -10 for fireworks
Intervening terrain: +1 for bare concrete (reflects
sound); -1 to -3 for heavy vegetation (muffles sound)
Listener distracted: -2 or -3 (see p. B548)
Listener unfamiliar with firearms (no points in Guns):
-4
Listener wearing winter clothing over ears: -1 to -3
Shot fired through pillow: -1
Suppressors work better on some guns than on others.
They’re most effective with sealed breeches such as boltactions
or dropping blocks: -1 to Hearing. They work fairly
well on semiautomatics, but such weapons often leak
high-velocity gas from the breech and always have
the noise of the action working (but see Slide-Lock,
p. 161). Suppressors don’t work at all on ordinary
revolvers; it’s possible to construct a revolver so tightly
fitted that it can be silenced (see Nagant R-1895,
p. 95), but this is more an exercise in perverted ingenuity
than in practical design.
A detachable suppressor requires a means to
attach it, usually an extended barrel with a thread or
attachment lugs. Attaching or removing a suppressor
takes five seconds if threaded, three seconds if a TL8
quick-detach model. Most suppressors add length to
the gun, worsening Bulk.
Baffle Suppressors (TL6)
Most suppressors are of this type. They work by
diffusing the muzzle blast and firing gases inside a
baffled expansion tube (which has many tiny compartments).
Lifetime is typically hundreds of shots –
even tens of thousands of shots, by late TL7.
Detachable Baffle Suppressor, .22-caliber (TL6). -1
to -4 Hearing. -1 Bulk. $100 per -1 Hearing, 0.25 lb.
LC3.
Detachable Baffle Suppressor, Pistol or SMG (TL6).
-1 to -4 Hearing. -1 Bulk. $250 per -1 Hearing, 1 lb.

Detachable Baffle Suppressor, Rifle (TL6). For rifles
firing 5.56¥45mm NATO, 7.62¥51mm NATO, or similar.
-2 to -4 Hearing. -1 Bulk. $250 per -1 Hearing, 1.5
lbs. LC3.
Detachable Baffle Suppressor, Oversized (TL8).
Primarily for large-caliber rifles, such as .50
Browning weapons, but also available for some MGs.
-2 to -4 Hearing. -2 Bulk. $400 per -1 Hearing, 5 lbs.
LC3.

=== Wiper Suppressors (TL6) ===

A wiper suppressor is a tube divided into compartments
by “wipes” placed perpendicular to the barrel.
The bullet passes through a sub-caliber hole in each
wipe, while blast and gases are trapped in the compartments.
Wipes are made of elastic materials such
as oiled leather, rubber, or polyurethane, designed to
close behind the bullet. This design means that wiper
suppressors slow the projectile (causing it to lose
power) and lose effectiveness after a few dozen shots,
but also makes them more effective suppressors than
baffle designs.

Detachable Wiper Suppressor, Pistol or SMG (TL6).
Multiply Dmg and Range by 0.8. Good for 40 shots.
-2 to -4 Hearing. -1 Bulk. $150 per -1 Hearing, 0.5 lb.
LC3.

Detachable Wiper Suppressor, Rifle (TL6). For rifles
firing 5.56¥45mm NATO, 7.62¥51mm NATO, or similar.
Multiply Dmg and Range by 0.5. Good for 40
shots. -2 to -6 Hearing. -1 Bulk. $150 per -1 Hearing,
1.5 lbs. LC3.

=== Dirty Tech: Home-Built Suppressors ===

To design a suppressor, make an Engineer (Small Arms)
roll. At TL7-8, a Research roll will suffice – instructions are
easy to find in survival guides and military manuals, and on
the Internet.

To build a suppressor, roll against Armoury (Small Arms),
which defaults to Machinist-5. Common modifiers include
up to +2 for actual blueprints or a working sample, the quality
of your tools (p. 24), and +1 to +5 for extra time (p. B346).
Failure means the first shot fired through the suppressor triggers
a roll on the Firearm Malfunction Table (p. B407); critical
failure damages the gun.

Suppressor quality modifies these assumptions and determines
the time required:

Poor-quality suppressors can be built in 30 minutes from
everyday items: tape, plastic bottles, Styrofoam chips,
chicken wire, etc. Those with the Guns or Armoury skill
don’t even need to roll; complete neophytes must make an
IQ roll. Poor suppressors last for only 1d shots and give just
-1 to Hearing rolls. They bestow -1 Acc, -1 Malf., and -1
Bulk, and weigh 0.5 lb.

Average-quality suppressors take two hours to assemble
from rubber washers, plastic pipe, and pipe fittings. They’re
slightly more complicated than poor-quality ones: an
Armoury roll is required, but at +4. (This is well-illustrated in
the film Ghost Dog.) Average suppressors last for 3d shots
and give -2 to Hearing rolls, becoming -1 to Hearing after firing
half the shots. They give -1 Bulk – but no Acc or Malf.
penalties – and weigh 1 lb.

Good-quality suppressors are home-made copies of low to mid-range commercial models (up to -3 Hearing). They
take eight hours to build and require a workshop (p. 24). Use
the stats for production suppressors, but price is 1/3 usual
(for materials) and weight is often slightly higher.
Fine-quality suppressors have all the requirements of
good suppressors, but take 16 hours to build and the skill roll
is at -2. Use the stats for the best available commercial suppressors,
but cost is 1/2 usual (for materials).

== Cinematic Silencers ==
The suppressor rules aim to represent realistic sound levels
– not the Hollywood fiction of near-silent gunshots. In a
cinematic campaign, the GM may wish to improve silencer
effectiveness dramatically, doubling or even tripling Hearing
penalties!

==== Stocks, Tripods and Bipods ====

Several add-ons are available to make guns more manageable.
Many firearms include these features in their cost
and weight, or don’t use the generic versions below – check
your weapon’s description first.
Pistol Stocks (TL5)
A removable shoulder stock can convert a handgun into
a carbine of sorts, improving accuracy and reducing felt
recoil at the cost of increasing weight and making the
weapon less handy. The pistol must be prepared to accept
the stock by having a slot or groove in the grip. Attaching
or removing the stock takes three seconds. While the stock
is attached, use Guns (Rifle) to shoot, add +1 Acc and -1
Bulk, and multiply ST by 0.8 (round up). Many stocks are
hollow, allowing storage of small items (ammo, a guncleaning
kit, etc.); some can hold the gun itself when it isn’t
in use.
Pistol Stock (TL5). $100, 1 lb. LC3.
Pistol Stock (TL7). $100, 0.5 lb. LC3.
Shooting Sticks (TL5)
Buffalo hunters sometimes propped long arms on
“bipods” made from crossed sticks fastened with rawhide
strips. A sitting marksman may treat a gun resting on shooting
sticks as braced (see Aim, p. B364). $5, 1 lb. LC4.
Tripods and Other Mounts (TL5)
Tripods are three-legged mounts for such heavy
weapons as machine guns and recoilless rifles. A tripod
provides at least a 180° arc of fire – those for antiaircraft
fire provide a 360° arc – and allows the weapon to be elevated
or depressed. The shooter usually sits or kneels
behind the tripod. While his weapon is mounted, he may
treat it as if it were braced and ignore its ST requirement;
see Aim (p. B364) and Bipods and Tripods (p. B412). Setting
up or collapsing a tripod typically requires six seconds.
Attaching or detaching the weapon takes a further three
seconds.
Some mounts have four or more legs, or wheels, or are
shaped like sleds. These use exactly the same rules as
tripods. Tripods and other mounts vary widely in cost and
weight, depending on materials and the weapons they’re
designed to support; see the individual weapon descriptions.
All such mounts are LC4.
Bipods (TL6)
Bipods are integral to some weapons – especially MGs –
and can be fitted to others. This is most common for rifles,
but SMGs and even long-barreled revolvers have been so
equipped! Bipods on MGs and heavy rifles function mainly
to relieve the shooter of some of the weight. Others are
installed for better accuracy.
If a weapon has an attached bipod, a prone shooter may
treat it as if it were braced (see Aim, p. B364) and multiply
its ST requirement by 2/3 (round up). Opening or closing a
folded bipod requires a Ready maneuver. If the shooter isn’t
prone, the GM may allow the bonus for bracing if the bipod
can reasonably be set on something stable – chest-high
wall, pile of sandbags, window ledge, etc.
Bipod (TL6). Available in fixed, semi-permanent, and
quick-detach models (five seconds to install/remove). $100,
2 lbs. LC4.
Bipod (TL7). As above, but $100, 1 lb. LC4.
Bipod (TL8). As above, but $100, 0.5 lb. LC4.
Folding Stock (TL7)
The fixed shoulder stock of some long arms – but not
that of weapons where the stock houses part of the action,
or the magazine – can be replaced with a stock that folds or
retracts to make the gun more compact. Folding such a
stock removes -1 from Bulk; firearms that already include
this feature indicate it with an asterisk (*) next to Bulk.
While folded, also apply -1 to Acc and +1 to Recoil (unless
Rcl is 1), and multiply ST by 1.2 (round up). Folding or
unfolding the stock requires a Ready maneuver. All but the
flimsiest folding stocks increase overall weight. $100, 0.5 lb.
LC3.

==== MISCELLANEOUS ACCESSORIES AND MODIFICATIONS ====

The following items can make a shooter’s life easier in a
variety of ways.

=== Gun-Cleaning Kit (TL4) ===

A clean gun has been the mark of the professional shootist
– from murdering thug to military sniper – since the
dawn of firearms. Black-powder marksmen usually carry a
multi-tool (p. 26) incorporating nipple key, vent pricker, oil
bottle, screwdriver, double-pronged worm for cleaning, and
tools for extracting jammed bullets. More modern kits fit in
a small pouch and contain collapsible cleaning rod, cleaning
patches, brush, cleaning solvent, and lubricant.
Machine gunners are often issued a belt pouch that
includes cleaning equipment and a few small spare parts.
For game effects, see Cleaning and Maintenance (p. 80).
$20, 0.5 lb. LC4.

=== Gun Case (TL5) ===

From the 1700s, high-quality dueling and target pistols
were traditionally kept in a wooden case with their accessories
– including a mold for the exact-sized ball. African
safari hunters kept their elephant guns in velvet-lined
strongboxes to protect against both the weather and lightfingered
porters. Padded aluminum and hard plastic cases
serve the same purpose today. A typical TL8 model is 4’ long
and holds a sniper rifle or two SMGs, plus spare magazines
and other accessories. It is waterproof and lockable, and
has DR 2. $250, 25 lbs. LC4.

=== Brass Catchers (TL6) ===

A “brass catcher” is a bag or other container attached to
a gun’s ejection port to catch spent cartridge cases (the
“brass”). Sport shooters use them to collect cases for
reloading (see Handloading and Reloading, p. 174).
Aircrews firing from within aircraft employ them to avoid
the dangers of hot brass flying around the cabin – or into
intakes or propellers. Covert operators, assassins, and others
who can’t afford to leave evidence behind also find them
useful. As a field expedient, soldiers sometimes tape a sturdy
plastic pouch (often taken from military rations, p. 35)
to the gun.

MG Brass Catcher (TL6). Holds 500 cases. Adds -2 Bulk.
$75, 2 lbs. LC4.

Pistol Brass Catcher (TL6). Holds 20-30 cases. Adds -1
Bulk. $50, 0.5 lb. LC4.

Rifle/SMG Brass Catcher (TL6). Holds 60-100 cases.
Adds -1 Bulk. $50, 1 lb. LC4.

In all cases, halve weight at TL8.

=== Slide-Lock (TL6) ===

A slide-lock prevents the action of a semiautomatic
firearm from cycling. This reduces mechanical noise when
used with a sound suppressor (pp. 158-159), giving -1 to
Hearing, but effectively converts the gun to a RoF 1 manual
repeater – the operator must rack the slide after every
shot to chamber a new cartridge. A slide-lock only comes
standard on such specialized weapons as the Izhmekh PB
(see Izhmekh PM, p. 100), but a gunsmith can add one to
any semiautomatic with an Armoury (Small Arms) roll and
two hours’ work. $50, neg. LC4.

=== Accessory Rails (TL7) ===

Many firearms feature integral rails for mounting accessories.
Typically located on the receiver of a rifle or under
the barrel of a modern pistol, these allow the user to attach
and detach accessories quickly (a Ready maneuver).

Weapons without rails require gunsmithing to provide a
stable mount for optics and sighting aids. Duct tape (p. 26)
will do in a pinch, but it won’t suffice for a device that gives
an Acc or skill bonus!

Strips of rail can be added to any suitable weapon surface
– notably the top of the receiver (for sights and scopes)
and around the forearm (for tactical lights, targeting lasers,
and underbarrel grenade launchers). Each rail typically
mounts one item, although long rails can hold more; e.g.,
an add-on night sight and a scope, front-to-back. A one-position
rail costs $100; a three- or four-position rail (sides,
plus bottom and/or top), $200. Integral rails have no
weight, but add-on versions increase weight by 0.2 lb. per
facing. LC4.

=== Drag Bag (TL7) ===

A sniper may use a padded “drag bag” to protect his rifle
while creeping along the ground. A typical bag is camouflaged,
has internal compartments and external pouches for
small items, and can be worn as a backpack. It may unfold
for use as a sniper mat once the sharpshooter reaches his
objective. Its thick skin has DR 1. $250, 4 lbs. LC4.


===== Ultra-Tech Firearm Accessories =====

In combat, any edge can mean the difference between
life and death – and technology is a great way to get that
edge. This section presents devices and modifications to
enhance almost any weapon.

=== Smartgun Electronics ===
Every TL9+ firearm has a laser sight (p. 149), a
HUD link (below), a recognition grip or transponder ring (p. 150), and a diagnostic computer (p. 151)
for free. These electronics are powered by an integral B cell, which is included in the basic weight of
the gun. A tiny computer (p. 22) may also be included. However, these components can be ignored if
they are not standard in a particular setting.

====Targeting Systems====
These help the shooter find his target and hit it.

===HUD Link (TL9)===
Connected to a heads-up display (p. 24), this shows augmented-reality targeting imagery in the user’s field of view.
The link shows him exactly where his firearm is pointing
(+1 Acc within 300 yards, not cumulative with the Acc
bonus for other targeting systems), the number of shots
remaining, and – if using a laser sight or other active targeting device – the distance to the target. The user can
exploit this to see around corners, exposing only his
weapon.

===Multispectral Laser Sight (TL9)===
This device projects a low-powered eye-safe laser beam,
placing a laser spot at the point where the weapon will hit.
A standard feature of all TL9+ firearms, it helps the user
aim or intimidate opponents.

A laser sight gives a +1 to skill when used out to the
weapon’s 1/2D range, provided the dot is visible to the
shooter. It can be set to use any one of these frequencies:

Visible Light: This projects a visible red, blue, or orange
spot. The laser beam itself is visible only in dusty or smoky
environments – which might describe many firefights!

Infrared: An infrared laser beam projects a dot that is
invisible without an infrared or hyperspectral vision system.

Ultraviolet: The dot of this ultraviolet laser beam is invisible without an ultraviolet or hyperspectral vision system.

===Compact Targeting Scope (CTS) (TL9-12)===
This video sighting system provides infravision at TL9
or hyperspectral vision at TL10-12. It has telescopic optics
for normal viewing in daylight, and interfaces with the
weapon’s HUD sight. It provides a +2 bonus to aimed shots
at TL9-10, +3 at TL11, or +4 at TL12.
The scope can also be used as a passive sensor, providing Infravision or Hyperspectral Vision with Restricted
Vision (Tunnel Vision). It has 4¥ magnification at TL9-10,
8¥ at TL11, or 16¥ at 12. The user must aim the weapon at
the target he is observing. $1,000, 0.5 lbs., A/100 hr. LC4.

===Enhanced Targeting Scope (ETS) (TL9-12)===
A powerful video sighting system used by snipers or
heavy weapons gunners. It provides hyperspectral imaging
(p. 61), plus telescopic optics for normal viewing in daylight. It interfaces with the weapon’s HUD sight.
The weapon’s sight automatically measures wind conditions, air temperature, and even local gravity conditions,
adjusting the weapon’s velocity to compensate.
The scope adds a +3 bonus to aimed shots at TL9-10, +4
at TL11, or +5 at TL12. Used as a passive sensor, it provides
Hyperspectral Vision with Restricted Vision (Tunnel
Vision) with 8x magnification at TL9-10, 16x at 11, or 32x
at TL12. The user must aim his weapon at the target he’s
observing. $8,000, 2 lbs., B/400 hr. LC4.

===Tactical Programs===
These programs augment the tactical or strategic acumen of police and military personnel by automating errorprone tasks. They assist the user without replacing him.

==Silhouette (TL9)==
This optical recognition program specializes in identifying targets of military interest and providing background or technical data. The quantity and accuracy of supporting
information depends on the databases used. High-quality
commercial databases offer expensive subscriptions and
constantly updated content, but lack detail. Military databases are usually encrypted and contain very detailed information, including hyperspectral emission profiles, countermeasure tactics, and usage instructions. Military databases
require Military Rank or Security Clearance. Complexity 5;
double normal cost.

==TacNet (TL9)==
A software tool (p. 25) useful for combat troops, TacNet
helps a leader monitor a combat force by tracking and displaying their positions, firing arcs, blind spots, command
relationships, and more. This gives a bonus to Tactics if all
parties are in communication. Complexity 5 (+1 Tactics),
LC3 or Complexity 6 (+2 Tactics), LC2. 10 times normal
cost.

==Targeting (TL9)==
This software tool augments the capabilities of a HUD
link (above) by improving target acquisition speed, ballistic modeling, environmental compensation (adjusting
for air pressure, wind, humidity, temperature, etc.), and
prioritizing targets for threat assessment. The program
gives a bonus to a single Gunner or Guns specialization if
used with a HUD link. Complexity 3 (+1 skill) or
Complexity 4 (+2 skill). Five times normal cost. LC2.

==Target Tracking==
Used in conjunction with a sensor system (see Chapter
3) such as a radar, radio direction finder, or hyperspectral
optics, this tracks up to 10 distinct targets or emission
sources at a time. It displays size, signal strength, bearing,
vectors, and other appropriate information on a movingmap display. Complexity 2; five times normal cost. Add +1
to Complexity and double cost per tenfold increase in tracking ability. LC4.

===Targeting with Active Sensors===
The most accurate way to aim a weapon is to slave a targeting program (p. 149) to a “tactical” active sensor that has locked onto a target. This feeds real-time ranging data to the gunner and shows the gunner
exactly how to move the weapon (or vehicle, if a fixed
weapon) to hit the target.

This can only be used for a mounted weapon (i.e., one
using Gunner skill). The combination of targeting program
and active sensor gives the maximum possible targeting
bonus. Replace all bonuses for scopes, computers, sensors,
etc. with a bonus equal to the weapon’s base Acc, up to a
maximum of +9. (Acc does still increase normally with Aim
maneuvers – +1 after one second, +2 after two seconds,
etc.)

In order to gain this bonus, the target must be in range
of the active sensor, and the program must be able to provide data directly to either the vehicle operator or whoever is operating the weapon mount.

====Other Accessories====
These accessories can be added to most of the weapons in this chapter.
===Accessory Rails (TL9)===
Firearms often have accessory rails for attaching optional systems such as sights and grenade launchers. Up to four
accessory rails per weapon are allowed (under barrel, over
barrel, side of stock, top of stock) but this will vary with
weapon size and configuration. $100 and 0.2 lbs. each.

===Gyrostabilized Weapon Harness (TL9)===
This articulated weapon harness (below) cancels the
penalty for a Move and Attack (see p. B365). It is $1,000,
plus $200 and 1 lb. per pound of loaded weight. LC4.

===Access Control (TL9)===
This electronic access system limits usage to authorized
persons. The weapon will not fire for unauthorized users.
Access control can be assigned to individual owners, but in
military and paramilitary organizations it is common to set
it so everyone in a unit can share the same weapons.
Deactivating or reprogramming the safety system requires
an Armoury (Small Arms) or Electronics Operation
(Security) roll at a -2 penalty. The first attempt takes 10 seconds; subsequent attempts require 10 minutes per try.

Transponder Ring: A ring worn by the user that contains
a radio transmitter with a one-inch range. The transmitter
sends a coded authorization message to the weapon, which
will not fire unless the correct ring is worn. The ring may
be permanently built into an armored suit glove, if desired.
$100. LC4.

Recognition Grip: A multi-function biometric scanner
built into the grip. It can respond to palm prints or voice
prints. It may also require both identifiers for maximum
security. $100. LC4.

==Self-Destruct Anti-Theft (TL10^)==
A miniature biosensor in the weapon’s handgrip automatically scans the genetic pattern of the holder. If that pattern matches one of the authorized users in its memory, the
weapon will fire. If not, the weapon will lock its firing circuits and begin a destruct sequence. It may or may not
warn its holder!

To abort the destruct sequence, the unrecognized holder must give the weapon’s computer a verbal authorization
code. If the correct code is not given in 10 seconds, the gun
self-destructs, doing 6dx4 explosion damage.
With the correct code (a single word and number
combination, e.g., “Wolf 323”) the weapon can be
reprogrammed to accept the biopattern of the holder. Each
code is unique to each weapon. Special codes are also
possible, such as one to delete biopatterns, or one which
causes the weapon to destroy itself immediately when fired.
Any attempt to circumvent the anti-theft system requires
proper tools and a roll against Electronics Operation
(Security)-3. Each attempt takes half an hour; failure activates the destruct sequence, while critical failure causes an
immediate explosion. $100. LC3.

===Articulated Weapon Harness (TL9)===
This is used to steady very heavy weapons. It straps on
and has a chest plate in front, with a supporting arm and
three hydraulic joints positioned to allow universal motion
and easy suspension. It has the same effect as a bipod (ST
requirement of the weapon is reduced by 2/3 and the
weapon counts as braced), but can be used while standing
up or moving. The user must still operate the weapon normally, using his own hands to aim and fire it.
The harness must be built for a specific weapon, and is
generally limited to weapons with Bulk -4 or more. It is $50
and 0.5 lbs. per pound of loaded weight for the weapon it is
built for – e.g., a harness for a 20-lb. machine gun is $1,000,
10 lbs. LC4.

===Diagnostic Computer (TL9)===
These smart integrated electronics give +1 to skill rolls
to fix damage or malfunctions. Diagnostic computers are
standard in all TL9+ firearms at no extra cost.

===D-Tag (TL9)===
This is a tiny receiver built into a weapon or other item.
Upon receiving a coded signal on a specific radio frequency, it sends out a return signal. D-tags are often built into police equipment, and some regimes may put them in
weapons sold to civilians. A successful Electronics
Operation (Security) roll is required to find it; a second roll
(at -2) must be made to deactivate it without disabling the
weapon or notifying the authorities. $20. LC4.

===IFF Interrogator (TL9)===
Friendly fire casualties are a constant problem on chaotic battlefields. An IFF interrogator identifies friends and
foes before a soldier pulls the trigger on the wrong target. A TL9 interrogator is an eye-safe IR or UV laser (usually built into a weapon’s standard laser sight) that emits a pulse-coded message at the target. TL10+ versions may differ in the type of signal beamed to the target, but the process is the same. This message contains an identification number, communication response frequency, and an encrypted code. If the target is wearing an IFF system (p. 188), then it can decipher the code and transmit a brief message in reply. The interrogator then identifies the target as friendly, unidentified, or known hostile. Feedback is displayed on the soldier’s
HUD sight or augmented reality display, but blinking LEDs on the interrogator also provide positive response.

IFF systems have some disadvantages: over-reliance on technical identification, difficulty using the IFF interrogator in cluttered environments, and the potential for compromising the user’s presence. The range of the IFF system is also limited: assume a range of 500 yards at TL9, doubling for each additional TL. Beyond this range, the GM may require Electronics Operations (Sensors) rolls to get a clear identification, with potentially disastrous results in the case of failure. $100.

===Power Holster (TL9)===
This is available for any pistol-type weapon or knife. It
consists of three parts: a wrist sensor unit, a homing sensor
on the handgrip of the weapon, and a break-away holster.
When the wrist sensor detects nerve impulses that mean
the wearer wants to draw, the holster ejects the weapon
toward the hand. This lets the weapon be readied instantly.
Each make of item requires a separate holster. A power holster adds +TL/2 to the Knife, Pistol, or Ammo specialization of Fast-Draw. $1,000, 2 lbs., B/100 uses. LC4.

===Sniper Mirror (TL9)===
A laser gunner using a visible-light laser may set up a
high-quality optical mirror for ambushes. The sniper can
fire at the target’s image in the mirror; the beam will reflect
off and strike the target. The mirror can be remotely controlled with a communicator.
The range is equal to the range of the target to the mirror, plus the range from the mirror to the sniper. The sniper is at -4 to skill when performing this maneuver.
When strategically placed (the GM may require a
Tactics or Traps roll), these mirrors allow a laser sniper to
fire around corners, and may confuse the enemy about the
direction from which fire is coming. The standard mirror is
about two feet across when in use, but folds to the size of a
paperback book. $500, 1 lb. LC4.

===Tripod (TL9)===
A tripod may be added to any mounted weapon (M notation next to ST), allowing it to be set up on the ground
rather than on a vehicle.
Ignore a weapon’s ST requirement when it is tripod-mounted. Removing the weapon from its tripod or reattaching it takes at least three Ready maneuvers.
A tripod provides a 180º arc of fire and allows the
weapon to be elevated or depressed. The weapon requires
two hands to use, and the user must usually sit or kneel
behind the tripod. A typical tripod can mount a weapon
that requires ST 25 or less, or any non-weapon sensor that
weighs up to 125 pounds. $1,250, 25 lbs. LC4.
===Powered Tripod Mount (TL9)===
A tripod can have an electric motor built into it. If the
weapon has a sensor such as a radar or motion detector
plugged into it (see Plug-in Gadgets, pp. 15-16), it can be
remotely controlled via computer. If the computer has
appropriate AI software, it can fire autonomously. A typical
powered tripod can fire any weapon that requires ST 25 or
less, or direct any non-weapon sensor up to 125 lbs. weight.
$5,000, 50 lbs. D/100 hr. LC4.
===Shoulder Servomount (TL9)===
This is a strap-on half-backpack with a gyrostabilized
servo arm. It holds a single weapon over the user’s shoulder. The weapon is aimed with a heads-up display, and can
swivel to fire at any target in front of the user.
The device has the same effect as a gyrostabilized
weapon harness, with the addition that the user does not
use his hands to control the weapon. This is equivalent to
the Extra Arm (Weapon Mount) advantage.
A servomount weapon should be used with a HUD. If
not, the user fires the weapon at a -2 penalty, and may not
take Aim maneuvers. An AI can also control a servomount,
freeing up the user for other activities, such as firing a
handheld gun.

It’s possible to wear up to two shoulder servomounts,
one over each shoulder. The gear is heavy, so shoulder servomounts are most often used by battlesuit troopers, or by nonhuman or disabled warriors who lack usable limbs.
A shoulder servomount is $5,000 plus an extra $1,000 and
3 lbs. per pound of weapon loaded weight. Thus, a servomount for a seven-pound weapon is $12,000 and 21 lbs. LC3.

===Smartgrip (TL10)===
