Faxon's Integral rifle barrels are the ideal solution for shooters who want the compact maneuverability of a shorter barrel while maintaining the flexibility of an AR-15 platform. With the integral muzzle device, there's no need to rely on a gunsmith to pin and weld a muzzle device to your barrel, offering increased versatility. The barrels come with a choice of a 3-port muzzle device or slotted flash hider, allowing for easy assembly and disassembly of the barrel and barrel nut, so you can easily change your weapon's configuration as needed. Faxon Firearms barrels are the pinnacle of quality and value. Manufactured in-house, these barrels are stress-relieved, air Gauge tested and finished with an 11 degree target crown for exceptional accuracy. We use only the highest-quality materials, either certified 4150 mil-spec steel or 416-R stainless, ensuring durability from the outset. Every barrel undergoes a rigorous testing process at each stage, then receives a nitride finish for added protection. Each one is individually inspected for headspace with precision custom hardened Gauges to guarantee top-tier performance. 11 degree target crown Integral slim flash hider Twist rate - 1:10 Barrel extension with Colt and Glock compatible feed ramps Blowback, button-rifled, pistol caliber tapered barrel
