The BATTLEARMS AUTHORITY series represents a new era in AR-15 design, meticulously crafted from the ground up for superior performance. At its core lies the billet BAD556 7075-T6 aircraft-grade aluminum receiver, featuring integral ambidextrous controls and a free-float rail handguard with M-LOK attachment points strategically placed at 3, 6 and 9 o'clock positions. The top rail boasts a full-length picatinny accessory rail with our distinctive notch cut to align seamlessly with the upper receiver. Each firearm in the series is outfitted with a 4150 chrome-moly steel barrel treated with black nitride for enhanced durability and accuracy. Every barrel undergoes precise individual head-spacing and is paired with a 9310 steel bolt and 8620 black nitride carrier to ensure unmatched reliability and effortless maintenance. Rifles in this series employ a Mid-Length gas system, optimizing cycling action for reliability, smooth operation, reduced recoil and minimal wear over time.
