FN M3M (GAU-21) MACHINE GUN - on this picture is mounted to FN Medium Ramp Pintle (FN MRP). The FN M3M (GAU-21) was designated by the U.S. Navy as the GAU-21. It is approved by the U.S. Department of Defense (DoD) for use by all branches of the military as the Common Defense Weapon System (CDWS) on all current and future rotary wing aircraft. An evolution of the M3AN .50-caliber machine gun, it produces 1,100 rounds per minute cyclic rate of fire using an open-bolt operation and a dual recoil buffer system. This system has been rigorously tested, evaluated and accepted by the DoD in order to provide warfighters with the best equipment to exceed their mission requirements while being extremely cost effective. Operating independent of either electrical or hydraulic power sources, the FN M3M(GAU-21) has a unique soft mount system that enhances accuracy and minimizes the recoil forces transmitted to the airframe. Receiver: Solid steel frame. Open-bolt operation limits heat build-up to reduce cook-off. Dual buffer system for reduced recoil forces. Barrel: Cold hammer-forged steel. Barrel life of 10,000 rounds. Enhanced flash hider. Perforated barrel jacket. Mount: Provides optimal field of fire with aircraft’s centerline for wider target coverage. Provides -70 degrees maximum depression angle for wider target coverage. Soft mount reduces recoil for both operator and airframe. Operating Controls: Vibration isolated dual spade grips. Manual re-cocking lever reduces cocking effort required. MIL-STD 1913 mount for sighting and target designation systems feed. Feed System: NATO standard disintegrating link belt feed for added reliability. Flexible metal ammunition belt guide system reduces misfeeds. Accepts ammunition boxes from 100 to 600 rounds for greater mission versatility. Fired link and case collection system for added aircraftand aircrew safety. Left or right-side ammunition feed.
