The BATTLEARMS® AUTHORITY™ series of firearms are designed from the ground up and purpose-built as the next generation AR-15. The heart of the rifle is the billet BAD556 7075-T6 aircraft grade aluminum receiver with integral ambidextrous controls and free-float rail handguard with M-LOK attachment points at 3, 6, and 9 o’clock positions. At 12 o’clock is a full-length Picatinny accessory rail with our signature notch cut matching the upper receiver. Every firearm is equipped with a 4150 chrome-moly steel black nitride barrel for durability and accuracy. Each barrel is individually head-spaced with a matching 9310 steel bolt and 8620 black nitride carrier for ultimate reliability and ease of cleaning.
