Weapon Upgrades

A character with the Trade (Armourer ) skill may upgrade weapons by making a successful test. The cost and availability of each upgrade refers to the component and not the cost of attaching it, which characters must pay for separately. For weapons purchased with upgrades already attached, simply add the cost of the upgrade to that of the weapon. This does not change the availability of the weapon. Upgrades also modify a weapon’s weight.

Compact

Compact weapons are smaller versions of pistol and basic weapons that are favoured by those that prefer concealment over stopping power. This upgrade halves the weight of the weapon but also halves its clip size and range as well as reducing its Damage by 1. Anyone attempting to find a concealed weapon with the Compact upgrade suffers a –20 penalty to any related Skill Test (e.g. Awareness, Search).
Upgrades: Any Pistol or Basic Las, Solid Projectile, Flame, Bolt or Plasma weapon.

Exterminator

Many of the more zealous religious warriors of the Imperium use an exterminator cartridge on their regular weapons. This small device contains a small one-shot flamer weapon that shoots out a sheet of fire. Rather than firing the weapon as normal, the shooter may use the exterminator cartridge, working out the effects as if he was armed with a flamer. Exterminators are one-shot weapons and must be replaced once used. You may attach an Exterminator to any weapon that rolls a 1d10 or more for damage. You cannot attach an Exterminator to a weapon with the Flexible quality, or to pistols. A Balanced weapon that has an Exterminator attached is no longer considered Balanced.
Upgrades: any non-pistol weapon that deals ≥ 1d10.

Extra Grip

Also known as a pistol grip, this allows the weapon to be wielded in one hand without the usual –20 penalty. However, it becomes more difficult to aim accurately and its Range is halved. You may choose to hold the weapon with two hands, in which case it will have normal range.

Upgrades: Any Basic ranged weapon.

Fire Selector

For weapons that can use differing ammunition rounds, a shot selector can be fitted for ease of switching from one type to another. A weapon with a fire selector can have up to three different clips added. At the start of the shooter’s Turn, he can use his fire selector to choose which clip he wishes to draw ammo from that round.
Upgrades: (Bolt) and (SP) Pistols or (SP) and (Bolt) Basic Weapons.

Melee Attachment

Bayonets and chain blades and other long-bladed combat attachments can be fitted to most ranged weapons, making them more useful in assaults. A weapon with a melee attachment counts as a spear in close combat.
Upgrades: Any Basic ranged weapon can have melee attachments.

Mono

Mono weapons have specially fashioned blades with superfine edges, which can easily cut through armour and never lose their edge. Mono weapons no longer count as Primitive and add a +2 bonus to their Penetration. The Mono upgrade can be applied to a power weapon, but it has no effect when the power field is active. If the power field is ever lost or deactivated, the Mono upgrade’s bonuses will then apply.
Note: The Mono upgrade may be applied to any melee weapon, but when applied to close-combat weapons that do not use an edge (e.g., hammers, mauls, etc.) it is defined differently. GMs are encouraged to come up with interesting definitions for non- edged weapons. For example, a hammer with the Mono upgrade is defined as having a pneumo-shock enhancement. The in-game effects remain the same.
Upgrades: Any primitive close combat weapon.

Red-Dot Laser Sight

This is a laser sight that grants a +10 bonus to Ballistic Skill Tests when the weapon is fired on single shot.
Upgrades: Any Pistol or Basic Las, Solid Projectile, Bolt, Primitive or Plasma weapon. A red-dot laser sight counts as a sight and a gun may only have one sight.

Silencer

Silencers lower the noise (and flash to a degree) from a weapon’s discharge, preventing detection of the shot. Awareness Tests to hear shots made with a silenced weapon suffer an additional –20 penalty and can only be attempted at half the normal distance for detecting gunshots.
Upgrades: Stub revolver, stub automatic, hand cannon, autogun and hunting rifle.

Telescopic Sight

Telescopic sights magnify the target’s image, especially useful for long-range shots that need to hit a very specific target location. A weapon with a telescopic sight ignores penalties for long and extreme range as long as the shooter takes a Full Action to aim.
Upgrades: Any Basic Las, Solid Projectile, Bolt, Primitive or Plasma weapon. A telescopic sight counts as a sight and a gun may only have one sight.

Auxiliary Grenade Launcher

A small single-shot, 45 range version of the regular grenade launcher fitted onto another ranged weapon such as a lasgun, allowing the user to either fire a single grenade instead of firing as normal. The added weight and cumbersome nature means that most users rarely bother to reload the launcher once it is expended. A character using a weapon with an auxiliary grenade launcher can choose to either fire the launcher or the weapon it is attached to in their Turn but not both at once.
Upgrades: Any Basic weapon.

Duplus Ammo Clips

Double-ended ammunition clips designed to shorten reloading time. Users simply flip the clip over when one side is exhausted. The clip is effectively two clips attached to each other and requires two clips worth of ammo to fill. A weapon with these special clips reduces their loading time by half (thus a weapon that takes two Full Actions to reload becomes a single Full Action). Normally only utilised by officers—troopers finding tape just as effective to holding to clips together, and a lot cheaper!
Upgrades: Any Basic, Pistol, Solid Projectile or Las weapon with a removable clip.

Forearm Weapon Mounting

As the name suggests, these heavy gauntlets allow for a single ranged weapon to be mounted along the arm, with specific hand movement triggering the weapon. This upgrade allows the user to keep both hands free. A weapon in a forearm mount functions as listed except that its range is reduced by 30%.
Upgrades: Any Primitive, Las, Solid Projectile, Bolt or Melta pistol.

Lathe Blade

The astronomical and gravitic alignment of the Lathe worlds creates the conditions for the production of metal alloys of rare and singular properties. Such a strange metal is used to fashion the legendary Lathe blade. So phenomenal is their strength and structure that they can have paper thin edges yet be flexible enough for the blade to resist breaking under the impact of the most powerful blows, and can even be unaffected by the devastating action of a power field. Some, including Lord Hax himself, favour a Lathe-forged blade over a power weapon such is their quality and repute.
A Lathe-bladed weapon loses the Primitive quality. Increase the weapon’s Damage by 2 and its Penetration by +3. Wielders of these weapons gain a +10 bonus on Weapon Skill Tests. A Lathe blade cannot be destroyed by the effects of a power field and counts as having an Armour value of 25 if directly attacked. A Lathe blade is automatically of the Best Craftsmanship (the effects of this have already been included in these rules). This upgrade cannot be combined with the Mono upgrade.
Upgrades: Knives, throwing knives, swords, axes and great weapons.

Sanctified Weapon

The prayers and blessing of those of true faith in the God- Emperor of Mankind, coupled with the ancient lore of Ecclesiastical alchemistry, is able to turn mere mundane blades into weapons that are capable of harming the foul denizens of the warp and other such unnatural horrors.
The sole effect of this upgrade is to make the Damage caused by the weapon in question counted as “Holy”, which has certain effects on some Daemonic and warp creatures (as will be noted in their description). Obtaining such items is only possible through the Holy Ordos or high-ranking members of the Ecclesiarchy, and the cost and rarity shown reflects this.
Upgrades: Any Primitive weapon (including Mono upgraded weapons) or Chain weapon of at least Good quality craftsmanship.

Targeter

Expensive, heavy and rarely used except by elite forces, a targeter uses a variety of guidance cogitators and omni-sights to improve accuracy. These upgrades are normally hard-wired into a specific weapon for maximum efficiency. Commonly viewed as adding to the weapon’s machine-spirit, they create an even closer bond between gunner and gun. A targeter grants a +10 bonus on all Ballistic Skill Tests made with the weapon.
Upgrades: Any Las, Solid Projectile, Bolt or Heavy weapon.

Tripods and Bipods

These attachments are for heavier weapons or those using integral ammunition canisters rather than a backpack- mounted source (such as plasma guns or meltaguns). Resting the weapon on the ground increases accuracy but sacrifices mobility, thus making them more common in static defence lines. Bipods and tripods allow a weapon to be braced anywhere there is a reasonably flat surface. A weapon braced on a bipod has a 90-degree fire arc while one on a tripod has a 180-degree arc. Bracing with a tripod requires a Full Action. Bracing with a bipod requires a Half Action.
Upgrades: Any Basic or Heavy weapon.
