BSF Barrels 7mm/284 20" 1:8 Twist Carbon Fiber Bolt-Action Rifle Barrel

The BSF Barrels SF3IYT0238 is a precision 7mm/284 bolt-action rifle barrel built for hunters and long-range shooters who want accuracy without the weight of a traditional all-steel profile. BSF pairs a button-rifled stainless steel bore with a carbon fiber outer wrap to produce a barrel that is noticeably lighter than a comparable steel profile while maintaining stiffness and consistent harmonics across extended strings of fire.

Cut to a 20" length, the SF3IYT0238 keeps velocity and maneuverability in balance for standard bolt-action rifle platforms. The button-rifled bore geometry creates uniform groove depth and a refined internal finish that promotes long barrel life and repeatable accuracy. The carbon fiber finish wraps the stainless steel core, providing a lightweight profile with efficient cooling characteristics during extended firing sessions.

A 1:8 twist rate stabilizes the wide range of modern 7mm hunting and precision projectiles, making this barrel equally at home on game and at the long-range target line. This is a new-production bolt-action rifle barrel ready for installation by a qualified gunsmith.
