BSF Barrels SF3IYT0270 .223 Rem 20" 1:7 Twist Carbon Fiber Bolt-Action Barrel 5/8x24

The BSF Barrels SF3IYT0270 is a precision bolt-action rifle barrel chambered in .223 Remington, built for rifle builders and shooters looking to upgrade or rebarrel a bolt-action platform.

BSF starts with a button-rifled 416R stainless steel match-grade blank and roll-wraps it under tension in a carbon fiber sleeve, delivering the accuracy of a stainless match barrel while shedding weight and adding rigidity. The 20" length pairs with a fast 1:7" twist rate that fully stabilizes modern heavy-bullet .223 Remington loads, from 55-grain practice ammunition through 77-grain and heavier match and tactical projectiles.

The muzzle is cut with a 5/8x24 thread pattern, ready to accept a wide range of muzzle brakes and suppressors. Finished in BSF's signature carbon fiber wrap and manufactured in the USA, the SF3IYT0270 is built for the precision bolt-action market.
