The BFG-50A is a magazine-fed, gas-operated .50 BMG rifle. It takes standard 10-round M-82 magazines. It has a 3-lug rotating bolt, dual plunger ejectors, sliding plate extractor, hydraulic recoil buffer. The bolt locks into a barrel extension which is threaded to the barrel. The bolt lug and barrel extension locking surfaces are helical. The gas system is similar to that used on a Ljungman AG-42 or MAS 49/56. As with our BFG-50 single-shot rifle, all our barrels are chambered with our own reamer design which allows surplus ammunition to be fired but gives far greater accuracy than can be achieved with barrels using a machine gun chamber. Barrel length: 26.0", overall length: 52.5". Rifle weighs 25 lbs unloaded. The BFG-50A uses a highly efficient 8-port "Shark Brake" muzzle brake. Barrel/barrel extension and handguard are removable to allow different barrel and handguard lengths and configurations.
