Brigade BM-15 Complete Upper 5.56 NATO 16" M-LOK Tungsten

The Brigade BM-15 is a complete AR-15 upper receiver kit chambered in 5.56 NATO, built around a 16" barrel — the minimum legal rifle barrel length under U.S. federal regulations, delivering higher muzzle velocity than shorter carbine or pistol-length configurations. The 16" barrel operates on a direct impingement gas system, providing a well-balanced platform for accurate shooting at extended ranges. The upper features a free-float M-LOK handguard offering ample rail space for optics, lights, and accessories. Finished in a tungsten cerakote or anodized coating, the BM-15 upper ships ready to mate with any mil-spec AR-15 lower receiver.
