M2HB and M2 QCB .50 Machine Gun

The US Ordnance M2HB is an air-cooled, belt-fed, machine gun that fires from a closed bolt, operated on the short recoil principle. The M2HB is capable of both sustained automatic and accurate single shot fire. The M2HB machine gun has been used extensively as a vehicle weapon and for aircraft armament by the United States from the 1920s to the present day. Ammunition may be fed from either the left or the right side of the gun, making it suitable for use by both infantry and in armored vehicles. The M2HB is in service with the U.S. Military and the armed forces of over 23 nations and is the world standard in heavy machine guns.

US Ordnance's most recent improvement to the time honored M2HB machine has been the addition of a quick change barrel with fixed headspace. Our innovative Quick Change Barrel (QCB) maintains fixed headspace and allows the barrel to be safely changed in seconds, allowing accurate pre-operational set-up and improving sustained fire support in battle.
