BSF Barrels 7mm Bolt Action Threaded AR Barrel 18" 5/8x24 Carbon Fiber Blank

Bsf Barrels Barrel Features The Bsf Barrels Barrel starts as a turned-down 416R stainless steel match barrel then is jacketed in a roll-wrapped carbon fiber sleeve applied under tension rather than simply wrapped over the surface. This jacketing method was selected specifically to avoid the heat trapping and delamination issues that have affected traditional surface-wrapped carbon fiber barrels. The carbon fiber material is engineered to expand at the same rate as the 416R stainless steel underneath helping the rifling stay straighter as the barrel heats up during extended use. When porting is selected slots machined into the carbon fiber allow air to move around the barrel and vent heat quickly without introducing delamination risk. Chambered in 7mm and built on a bolt action this 18 inch barrel carries a 1:8 twist rate suited to common 7mm bullet weights for stable flight at distance. A 5/8x24 thread pattern provides compatibility with a wide range of muzzle devices and suppressors. Button rifling delivers a smooth consistent bore surface that supports long-term accuracy and easier maintenance. By keeping the barrel under tension throughout the wrapping process Bsf Barrels achieves superior stiffness and strength while keeping the barrel extremely lightweight making it a strong option for precision bolt action builds for sale at ARMSAGORA.
