The Battle Arms Development Authority Elite SBR is a compact 5.56 NATO and .223 Wylde AR-platform rifle built around billet 7075-T6 aluminum receivers with integral ambidextrous controls. Battle Arms designed the Authority series from the ground up as a next-generation AR-15, with a free-float M-LOK handguard and a full-length Picatinny top rail. The 10.5-inch barrel is 41V50 steel with a black nitride finish, and each barrel is individually head-spaced to its bolt. The short barrel and ambidextrous layout suit training, range use and close-quarters setups.
