The M82 Assault Rifle is the standard-issue assault rifle using the 6.8 x 43 mm SPC cartridge and was manufactured by ISA Weapon Systems. The technical aspects of the M82 consists of a proprietary gas system to avoid malfunctions and a short-stroke piston driving an operating rod to force the bolt carrier to the rear. This design prevents combustion gases from entering the weapon's interior, a shortcoming with direct impingement systems. These features increase the reliability and decreases the cleaning time of the weapon. It is currently under the possession of the Alliance of Nations.
