Product Description The BSF Barrels SF3IYT1191 is a premium bolt-action rifle barrel engineered for shooters who demand superior accuracy and a significant reduction in overall rifle weight. Chambered in 257 Weatherby Magnum, this 20-inch barrel pairs a precision-ground, button-rifled stainless steel core with a carbon fiber wrapped exterior, delivering the ideal balance of rigidity, corrosion resistance, and lightweight performance. The 1:7.5″ twist rate is optimized to stabilize a wide range of 25-caliber projectiles, while the 5/8″x24 threaded muzzle end provides compatibility with a broad selection of muzzle devices and suppressors. Whether you are building a backcountry hunting rifle or a long-range precision platform, the SF3IYT1191 is crafted to deliver consistent, repeatable results. Product Highlights Carbon Fiber and Stainless Steel Construction: Carbon fiber wrap over a stainless steel liner reduces weight to just 39 oz while maintaining the strength and heat dissipation needed for extended shooting sessions.

Optimized 1:7.5″ Twist Rate: Designed to stabilize modern high-ballistic-coefficient 25-caliber bullets for flat-shooting, long-range performance. 5/8″x24 Threaded Muzzle: Industry-standard threading allows direct attachment of muzzle brakes, flash hiders, and suppressors for versatile configurations.
