The Brigade Mfg. BM-15 is a semi-auto AR-15 pattern rifle chambered in 5.56x45mm NATO, built around a 16-inch barrel, the minimum length federal law allows for a rifle-configured AR (brand part no. A5611613M). A direct gas impingement system cycles the action, while a 7075-T6 aluminum forged receiver finished in Cerakote keeps the rifle durable through hard use. The M-LOK free-float handguard gives plenty of real estate for lights, optics, and other accessories, and a 6-position adjustable stock lets shooters dial in length of pull. It is a straightforward, mil-spec-pattern rifle built for the range, competition, or home defense.
