The Brigade Bm-15 5.56 is a compact AR-15 platform pistol built for shooters who need a maneuverable, space-efficient firearm without sacrificing core performance. With a 5-inch handguard, this is the shortest offering in Brigand Arms' BM lineup—making it genuinely portable for backpack transport, truck storage, or tight-quarters work. It chambers 5.56x45mm NATO, runs a direct impingement system, and features a 4150 chrome-moly vanadium nitride barrel with a 1:5 twist rate for reliable accuracy across standard 5.56 ammunition.
Built on a mil-spec trigger and direct-impingement platform, the Bm-15 handles like a rifle in miniature. The M-LOK free-float rail gives you genuine mounting flexibility without the bulk of a full quad-rail, and the ambidextrous charging handle and safety selector mean lefties and righties both operate it naturally. The SBA3 tactical brace is removable, giving you options depending on your setup and local regulations. An A2 pistol grip rounds out the ergonomics—a familiar, proven design that works for most hands.
Construction centers on 7075-T6 aluminum forgings throughout the receiver, finished in Cerakote for durability in field conditions. Whether you're building a truck gun, a training rig, or a compact home-defense platform, the Bm-15's short profile and proven AR-15 compatibility mean parts support and customization options are endless. This is a no-nonsense pistol for shooters who value function over flash.
