***NOTE*** Due to barrel shortages, current shipments will include some with 5.56NATO barrels, thank you for understanding. 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 matching Carpenter 158 steel bolt and 8620 black nitride carrier for ultimate reliability and ease of cleaning. Rifle models utilize a mid-length gas system for reliable and smooth cycling action while reducing recoil and minimizing wear.
