The Serbu BFG-50A is a magazine-fed, gas-operated .50 BMG rifle. It takes standard 10-round Barrett 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 BFG-50 single-shot rifle, all barrels are chambered with a 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. Bi-pod is included, but the pictured scope is not.
