Product Description The BSF BARRELS SF3IYT0270 is a premium bolt-action rifle barrel chambered in 223 Rem, engineered for shooters who demand both precision and lightweight performance. BSF Barrels constructs this barrel by first turning down a 416R stainless steel match-grade core, then jacketing it in a roll-wrapped carbon fiber sleeve loaded under tension. Unlike simple barrel wraps, this jacketing method prevents the heat-trapping and delamination issues associated with conventional carbon fiber wrapping. The carbon fiber material is specially formulated to expand at the same rate as 416R stainless steel, keeping the rifling straighter as the barrel heats up. The result is a barrel that maintains superior stiffness and structural integrity while remaining remarkably lightweight -- ideal for long-range bolt-action builds where weight savings and thermal stability are critical. The 20" barrel features a 1:7" twist rate optimized for stabilizing heavier 22-caliber projectiles, and a 5/8"x24 threaded muzzle for suppressor or muzzle device attachment. Product Highlights 416R Stainless Steel Match Core: Button-rifled, match-grade stainless steel barrel core ensures exceptional accuracy and long service life. Roll-Wrapped Carbon Fiber Jacket Under Tension: Patented jacketing technique prevents heat buildup and delamination while maintaining superior rigidity and reducing overall weight. Thermally Matched Materials: Carbon fiber sleeve is engineered to expand at the same rate as 416R stainless steel, preserving bore geometry and accuracy as the barrel heats up. Lightweight and Rigid Design: At 39.70 oz for a full 20" barrel, the carbon fiber construction dramatically reduces weight compared to an all-steel barrel without sacrificing strength or stiffness. Threaded Muzzle Ready: 5/8"x24 thread pattern allows direct attachment of suppressors, muzzle brakes, or compensators.
