BSF Barrels SF3IYT0262 223 Remington 20" 1:8 Twist Carbon Fiber Bolt-Action Barrel

The BSF Barrels SF3IYT0262 is a precision bolt-action rifle barrel chambered in 223 Remington and built around a button-rifled 416R stainless steel core that is roll-wrapped in a tension-loaded carbon fiber sleeve. Made in the USA by BSF Barrels, the design pairs a match-grade stainless blank with a lightweight, heat-dissipating carbon fiber jacket to deliver a rigid, accurate barrel that weighs noticeably less than a comparable all-steel contour of the same length.

This 20" tube is cut with a fast 1:8 twist that stabilizes a wide range of bullet weights and is equally at home chambering 223 Remington and 5.56 NATO ammunition. The button-rifled bore, finished 416R stainless core, and tension-wrapped carbon fiber wrap give shooters a stiff, fast-dissipating platform well suited to precision bolt-action rifle builds, varmint and predator rigs, and hunting applications where shot-to-shot consistency and weight savings both matter.

BSF Barrels builds their carbon fiber barrels in the USA, starting with a precision-turned 416R stainless match-grade barrel blank and encasing it in a roll-wrapped carbon fiber sleeve loaded under tension. The carbon wrap vents heat from the bore and resists delamination under extended strings of fire, and gives the finished tube its distinctive two-tone stainless-and-carbon appearance. This listing is for the SF3IYT0262 bolt-action model in 223 Remington with a 20" length and 1:8 twist.
