Assault rifle

''This page redirects from Ar. For the Noble gas, see Argon'' An assault rifle is a selective-fire firearm using a projectile with a muzzle energy in between those of a full-sized rifle and a smaller submachine-gun or a pistol. Assault rifles are categorized in between battle rifles, which fire a full-sized rifle cartridge, and submachine guns, which fire a pistol cartridge rather than a rifle cartridge. Examples of assault rifles include the M16, AK family, G36, FN SCAR, and the Steyr AUG.
