The BFH-series barrel is a highlight: a 16-inch, cold hammer forged BCM unit that is individually high-pressure and magnetic-particle tested. It uses a carbine-length gas system with a pinned A2 front sight base and a threaded muzzle fitted with a BCM-marked compensator/flash device. The 1:7 twist supports a wide range of 5.56 NATO projectiles.
U.S. Army engraved details set this rifle apart. The magwell bears the U.S. Army star over 'U.S. ARMY' for a distinctive, service-themed appearance that is cleanly executed and prominently placed.
The sighting system is simple and durable: an A2 fixed front sight base paired with a Daniel Defense fixed rear sight. Controls are enhanced with a Magpul B.A.D. Lever for efficient bolt catch manipulation. Selector markings are SAFE and SEMI, and the rifle uses a standard manual safety.
Built on forged aluminum receivers with a black anodized finish, the upper is a flat-top with T-marked Picatinny rail, forward assist, case deflector, and a delta ring assembly. The ejection port cover interior is marked 'BCM' and the upper receiver shows an 'A' forging mark. Furniture includes a tan collapsible stock and tan polymer pistol grip, plus a two-piece, carbine-length polymer handguard with an installed Magpul MOE vertical foregrip. Length of pull is 10.25 inches.
