Product Description The BSF Barrels SF3IYT0058 is a precision-engineered carbon fiber AR-10 barrel chambered in 6 Creedmoor, purpose-built for shooters who demand long-range accuracy without the burden of excess weight. Stretching 20 inches in length and featuring a 1:7.5 twist rate, this semi-auto barrel is optimized to stabilize the heavy, high-ballistic-coefficient projectiles that make 6 Creedmoor a premier long-range cartridge. The carbon fiber sleeve with slotted fluting dramatically reduces weight compared to traditional all-steel barrels while simultaneously promoting heat dissipation during sustained fire. A stainless steel core liner maintains consistent bore geometry and long-term durability, making the SF3IYT0058 an outstanding centerpiece for a precision AR-10 build.
