Upgrade your AR-10 platform with the pinnacle of barrel technology: the Proof Research AR-Style .308 Winchester 16" Carbon Fiber Barrel (Part 101261). Designed for tactical shooters, hunters, and precision competitors who refuse to compromise, this match-grade barrel combines aerospace-grade carbon fiber with a 416R stainless steel core to deliver exceptional accuracy and substantial weight savings. By utilizing an advanced carbon fiber wrapping process, Proof Research tensions the inner core to virtually eliminate thermal drift and stringing, ensuring your point of impact remains true even during rapid-fire strings.

Optimized for superior handling and reliability, this 16-inch barrel features an intermediate length gas system that provides a smoother, softer recoil impulse and more reliable cycling than standard carbine or mid-length setups. It features a 1:10" twist rate with 5-groove rifling, perfectly tailored to stabilize a wide range of heavier, high-ballistic-coefficient match and hunting projectiles. Finished with standard 5/8"-24 TPI muzzle threads, it is fully compatible with your favorite suppressors, muzzle brakes, and flash hiders. Whether you are building an agile hunting rifle or a high-performance competition gas gun, this Proof Research carbon fiber barrel delivers unmatched harmonics, superior thermal dissipation, and legendary accuracy straight out of the box.
