The Brigade Arms BM-15 5.56 pistol with 10.5-inch barrel and SBA3 brace delivers serious capability in a compact platform built for shooters who want modularity without sacrificing control. This AR-15 pistol combines a free-floating M-LOK handguard with a 10-inch rail system that gives you abundant real estate for optics, lights, lasers, and other accessories—all while keeping the overall footprint nimble enough for CQB work, range sessions, and short-to-medium distance applications where a short-barreled rifle form factor makes sense.
Built on the AR-15 platform, the BM-15 uses a direct gas impingement operating system and feeds 5.56x45mm NATO ammunition through a reliable, proven design. The 4150 chrome-moly vanadium nitride barrel sports a 1:7 twist rate suited to stabilizing a wide range of 5.56 loads. Ambidextrous controls—charging handle and safety selector—keep the gun equally friendly to lefties and righties, while the A2 pistol grip and mil-spec trigger anchor you with familiar ergonomics and predictable break.
The SBA3 tactical brace gives you a solid cheek weld and support platform, and the Cerakote finish on 7075-T6 aluminum forgings resists corrosion and abuse. If you're building a truck gun, a training platform, or a compact fighting carbine, the BM-15 rewards upgrading with quality optics, mounting systems, and hand placement options.
