The upper assembly is a Bravo Company forged receiver with forward assist and dust cover, noted by the seller as a factory cosmetic-blem designation. The build retains AR-15 pattern features including a shell deflector and ejection-port cover, and presents with a continuous T-marked top Picatinny rail.
Barrel components are top-tier: a Ballistic Advantage 16 in 4150 CMV cold-hammer-forged Hanson-profile barrel, a mid-length gas system, and a pinned low-profile gas block. The muzzle is threaded and fitted with an A2-type flash hider.
For rigidity and accessory mounting, the rifle uses a B. King’s Firearms 15 in free-float aluminum M-LOK handguard with anti-rotation tabs. Controls include a BCM ambidextrous charging handle with extended latches and an ambidextrous SAFE/FIRE selector.
Internals are built for durability: a mil-spec Carpenter 158 phosphate bolt carrier group and a carbine receiver extension with an H2 buffer. Furniture includes a B5 Systems Type 23 grip and trigger guard and a black adjustable 6-position B5 Systems Bravo Stock. The lower is a Watchtower Type 15M marked “WATCHTOWER – SPRING, TX – TYPE 15M – MULTI” with the Watchtower crest on the magwell, and uses Sons of Liberty Gun Works lower parts and trigger. Receivers and handguard are 7075-T651 forged aluminum with a matte black anodized finish, and the magwell is STANAG-compatible.
