Ammunition Modifications Firearms (by ammo type)

Modifications (or mods) can only be applied to weapons that use the handguns, rifles, submachine guns and shotguns skills. They can modify any parameter of a firearm and/or add new features to it (such as an auxiliary weapon).

To use a mod you need to apply the mod to attach it to the desired weapon, assuming you have the correct level in the firearms skill. A single weapon can only hold a limited amount of modifications in each modification slot. Read the description of the weapon. You can easily check how many mods are attached to a weapon by examining its name: each modification will add a plus (+) sign to it. Added plusses don't mean additional damage, just additional mods, a plus can be anything from a sling to an attached grenade launcher.

All modifications can be removed at any time by aactivating the gun, a menu will ask you which mods to remove.
