The XM 450 an air cooled, gas operated, belt fed, automatic weapon. The 450 is operated using conventional gas action with the gas piston located above the barrel, and the barrel is locked using the traditional rotary bolt. The barrel is quick-detachable for quick replacement procedure. The 450 has an alternative feed system, which allows to use disintegrating metallic belts as a primary feed option, or M16-type box magazines as a back-up feed option. The belt is feed using the top feed unit, the magazines are inserted through the magazine port. Since the belt feed uses additional power to pull the belt through the gun, the rate of fire with the belt is somewhat slower (~ 750 rpm) than the rate of fire with magazine feed (~ 1000 rpm).
