Barrett 12808 M107A1 50 BMG 10-Rd Black Steel Box Magazine

The Barrett M107A1 50 BMG 10-round box magazine is a factory OEM replacement built specifically for the Barrett M107A1 semi-automatic rifle. Engineered to feed the massive .50 BMG cartridge, this magazine features heavy-gauge steel construction with a durable black finish and a 10-round capacity.

Built to Barrett's factory specifications, the magazine body is formed from steel to withstand the punishing recoil of sustained 50 BMG semi-auto fire. The black finish provides corrosion resistance in field conditions, and the traditional box design delivers reliable feeding of 10 rounds per load. A cartridge witness window allows quick visual round-count checks at a glance, and the detachable design drops free cleanly for fast reloads.

Whether you need a primary magazine for range work, a spare for extended long-range sessions, or a direct replacement for a worn unit, this Barrett M107A1 10-round steel box magazine delivers the fit and function of original factory equipment. Model 12808.
