The U.S. Ordnance M2QCB NATO machine gun is an air-cooled, belt-fed
machine gun that fires from a closed bolt and operates on the short recoil
principle with fixed headspace and timing. It is capable of both sustained
automatic and accurate single-shot fire. It can be mounted on a vehicle, boat,
helicopter or other aircraft. Ammunition may be fed from either the left or right
side for use by both infantry and in armored vehicles. U.S. Ordnance’s M2A2
weapon system has been tested to well over 50,000 rounds. This is a
multi-breech lock system that is compatible with systems in use by NATO.
