Product Description The BSF Barrels SF3IYT0090 is a premium AR-10 platform barrel engineered for precision and performance. Chambered in .308 Winchester, this 20-inch semi-auto barrel features a distinctive carbon fiber wrapped construction that dramatically reduces overall weight without sacrificing rigidity or durability. The carbon fiber sleeve is wrapped over a steel core and includes ventilation slots along its length to aid in heat dissipation during sustained fire. A polished stainless steel gas block journal and threaded muzzle complete the build, making it a standout upgrade for any serious AR-10 rifle build. With a 1:10 twist rate, this barrel is optimized to stabilize a wide range of .308 Win projectiles for consistent, long-range accuracy. Product Highlights Carbon Fiber Wrapped Construction: Lightweight yet rigid carbon fiber sleeve reduces barrel weight significantly compared to traditional steel barrels while maintaining structural integrity. 308 Winchester Chambering: Optimized for .308 Win (7.62x51mm NATO) cartridges, offering versatility for hunting, competition, and tactical applications. 20-Inch Barrel Length: Full 20-inch length maximizes muzzle velocity and long-range ballistic performance on the AR-10 platform. 1:10 Twist Rate: A 1:10 rifling twist rate provides excellent stabilization for a broad spectrum of .308 Win bullet weights. Threaded Muzzle: Threaded muzzle end allows for the addition of muzzle devices such as compensators, brakes, or suppressors.
