The Battle Arms Development BAD-AUTH-UR16B-Y-15 Authority Elite Complete Upper Receiver is a premium billet AR-15 assembly engineered for elite performance in competition, duty, and tactical applications. Built around a fully machined BAD556 7075-T6 aluminum upper receiver with integrated ambidextrous controls, it delivers superior rigidity and ergonomics compared to standard forged uppers. Paired with a 15-inch free-float M-LOK handguard featuring a continuous Picatinny top rail and M-LOK slots at 3, 6, and 9 o'clock, this upper provides excellent modularity while maintaining a sleek, cohesive profile.
It comes equipped with a 16-inch 4150 Chrome-Moly Vanadium nitride barrel, a head-spaced 9310 alloy steel bolt in a black nitride 8620 carrier, and the BAD-RACK-15 ambidextrous charging handle for reliable, snag-free operation from any angle. The mid-length gas system and tuned low-profile gas block ensure smooth cycling with minimal recoil across various ammunition types.
