Manufactured in-house, our barrels undergo a rigorous process to guarantee exceptional accuracy and performance. Each barrel is fully stress-relieved, air Gauge tested and finished with an 11 degree target crown. We begin with the highest-quality materials, choosing either certified 4150 mil-spec steel or 416-R stainless and subject each barrel to a series of tests throughout the manufacturing process. After being treated with a durable nitride finish, every barrel is carefully inspected and headspace is individually checked using precision custom hardened Gauges. Quality is built into every step, ensuring top-tier reliability and performance. 11 degree target crown Twist rate - 1:10 Barrel extension with Colt and Glock compatible feed ramps Blowback, button-rifled, pistol caliber tapered barrel
