The BCM4 platform here is a compact .300 BLK SBR built around a 9 inch, threaded barrel capped with a three-prong flash hider. The free-float BCM KMR-A8 aluminum handguard (8.0 inches) isolates the barrel and carries T-marked Picatinny positions from T18 to T32, while the upper receiver's rail is T-marked from T2 to T14.
Controls and furniture are purposefully configured: an AXTS Raptor ambidextrous charging handle with FDE levers, an adjustable FDE stock, and a Magpul MOE FDE pistol grip. The rifle uses a direct impingement action with a manual safety selector marked SAFE/SEMI and accepts AR-15/STANAG magazines with a 30+1 capacity.
Factory and component markings are present throughout: the upper is marked '300 BLACKOUT'; the lower is roll-marked '★BCM RIFLE COMPANY • MODEL BCM4 • CAL MULTI'; the right side reads 'BRAVO COMPANY MFG., INC., HARTLAND, WISCONSIN USA'; and the handguard is marked 'BCM-KMR-A8 • MADE IN USA • PAT 8904691'. The receiver also bears an NFA trust engraving reading 'MILLER TRUST • SOUTH LYON, MI.', indicating prior NFA registration.
This NFA item SBR is finished in matte black anodizing on the receivers and is made in the United States. No sights or optics are installed, leaving the T-marked top rails clear for the buyer's preferred setup.
