The Battle Arms Development Bad 10.5 Uppr Auth Elite 556 C Blk is a complete AR-15 upper receiver built around a billet BAD556 7075-T6 aluminum receiver and a free-float M-Lok handguard. Its 10.5" 5.56 NATO barrel uses a durable 4150 chrome-moly steel construction with a black nitride finish, paired with a matching AR-15/M16 bolt carrier group for smooth, reliable cycling. Integral ambidextrous controls and the included Bad Rack-15 C ambidextrous charging handle make this upper easy to run from either shoulder while maintaining a sleek, modern profile.

This compact 10.5" upper is well suited for range use, training, and building a maneuverable AR-15 configuration where reduced overall length is desired. The full-length Picatinny rail and M-Lok handguard provide ample space for lights, grips, and other accessories, allowing shooters to tailor the setup to their preferences. With its precision head-spaced barrel, robust materials, and thoughtful ambidextrous design, this Authority Elite upper reflects Battle Arms Development’s focus on quality machining and innovative ergonomics.
