Brigade Bm-300 300Blk 10.5 Fde Sba3 Mlok A2
The Brigade BM-300 is a .300 Blackout pistol built on the AR-15 platform, engineered for shooters who want a compact, versatile semi-auto firearm. With its 10.5-inch barrel and SBA3 tactical brace, this pistol delivers the ballistic performance of .300 Blackout in a maneuverable package—ideal for home defense, close-quarters shooting, and suppressed shooting where subsonic ammunition really shines. The FDE (Flat Dark Earth) finish and modern ergonomics make this a capable option for tactical training, short-range hunting, and recreational shooting.
Construction centers on quality materials: the upper and lower receivers are CNC machined from 7075-T6 aluminum forgings, and the 4150 chrome-moly barrel wears a durable nitride finish. The 1:7 twist rate handles a broad range of .300 Blackout loads, from heavy subsonic rounds to faster supersonic ammunition. Gas impingement operation keeps maintenance straightforward and reliability proven. You get an A2 flash hider at the muzzle, a mil-spec trigger, and an ambi charging handle that works for both right- and left-handed shooters—practical touches that add up in the field or on the range.
The 10-inch M-Lok rail runs the length of the handguard, giving you room to mount optics, lights, lasers, or other modern accessories. The SBA3 brace provides adjustability and a secure shoulder connection, while the included 30-round magazine and 3-ounce buffer round out the shooter-friendly package. Whether you're suppressor-ready, ammunition-curious, or just looking for a shorter, handy .300 Blackout platform, the BM-300 delivers solid AR ergonomics without compromise.
