BSF Barrels SF3IYT0261 .223 Remington 18" Carbon Fiber Bolt-Action Barrel 1:8 Twist 5/8x24

The BSF Barrels SF3IYT0261 is a precision bolt-action replacement barrel chambered in .223 Remington, built on a button-rifled 416R stainless steel core and encased in a roll-wrapped carbon fiber sleeve loaded under tension. The carbon fiber jacket is micro-perforated to vent heat and gas, preventing delamination and keeping the barrel remarkably light for its length while maintaining match-grade accuracy.

This model features an 18" barrel with a 1:8 twist rate, a well-balanced rate that stabilizes a wide range of .223 bullet weights from light varmint projectiles to heavier match and hunting bullets. The barrel is threaded 5/8x24 for standard muzzle device or thread protector fitment.

Manufactured by BSF Barrels in the USA, the SF3IYT0261 is designed as a drop-in barrel for compatible bolt-action rifle platforms. Each barrel is built from a precision-turned 416R stainless steel match-grade blank, button rifled, then wrapped in carbon fiber under tension to produce a rigid, lightweight, and thermally stable profile favored by precision rifle shooters and hunters alike.
