Product Description The BSF Barrels SF3IYT0677 is a precision-engineered bolt-action barrel chambered in 6mm/243, purpose-built for long-range shooters who demand accuracy without sacrificing weight savings. Featuring a stainless steel core fully wrapped in a carbon fiber finish, this 22-inch barrel delivers outstanding rigidity and corrosion resistance while keeping overall weight to a minimum. The button-rifled bore maintains tight, consistent tolerances from breech to muzzle, ensuring exceptional shot-to-shot repeatability. A 1:7.5" twist rate is specifically dialed in to stabilize the full spectrum of 6mm projectiles, and the 5/8"x24 threaded muzzle crown opens compatibility with suppressors and a wide range of aftermarket muzzle devices. Product Highlights Carbon Fiber Over Stainless Steel Construction: Merges the corrosion resistance and strength of a stainless steel liner with the significant weight reduction of a carbon fiber outer wrap for a high-performance rifle barrel. Button Rifled Bore: Precision button-rifling process produces a smooth, uniform bore with consistent land and groove dimensions for superior accuracy and long-term durability. Optimized 1:7.5" Twist Rate: Purpose-matched to 6mm/243 caliber projectiles to ensure stable flight across a broad range of bullet weights, making it ideal for competitive and long-range precision shooting. 5/8"x24 Threaded Muzzle: Standard threading provides broad compatibility with suppressors and muzzle brakes, adding versatility for both field and range use. Lightweight at 41.10 oz: The carbon fiber wrap substantially reduces barrel weight compared to full stainless alternatives without compromising stiffness or accuracy potential.
