ARX-16

 The ARX-16 is an Assault Rifle featured in Call of Duty: Annihilation.

Multiplayer
'''The ARX-16 is the first assault rifle to be unlocked, available at level 4. It features moderate shot damage, taking at least three rounds to kill up close even if all three are headshots. It can take up to 4 rounds at longer ranges, although this is reduced to three rounds if one is a headshot. It has moderate- low recoil and reasonably clear iron sights, which makes the ARX-16 a highly versatile weapon that lacks a pressing need for any specific attachment.'''
