Weapon accessories are devices intended to be installed on weapons, typically firearms, in order to improve or modify their functionality or performance.

There are five categories of weapon accessories: Feeding systems, Muzzle devices, Underbarrel devices, Optics, and Lights.

The term feeding system is a catch-all for any object whose primary function is to carry ammunition and feed it to a weapon. Eight types of items can be found in this category: Magazines (including en-bloc clips, which are considered mechanically identical to magazines), Moon clips, Speedloaders, Speed strips, Ammo belt boxes, Belt links and Reload packs.
