Description
The Faxon Duty Series Gunner Profile 18" .308 Win AR10 Barrel is designed to address common concerns with AR-10 rifles, namely weight and recoil. This barrel features a rifle-length gas system, which provides the softest recoil impulse possible for a big-bore AR. The Gunner profile maintains a .750" body behind the gas block, a .875" step at the block, and a .600" section ahead, resulting in a lightweight construction at just 2.13 lbs. This design allows users to reduce the overall weight of their rifle while enhancing accuracy, making it ideal for hunting, designated-marksman roles, or general-purpose use.
Constructed from 4150 CMV steel, this barrel is button rifled with a 1:10 twist and features a salt-bath QPQ nitride finish for enhanced hardness and corrosion resistance. The barrel is shipped with a DPMS-pattern .308 extension installed and headspaced, ensuring reliable performance. It has been recognized as a top aftermarket barrel, receiving the Gold Award from Shooting Sports Retailer every year since 2022.
