Bsf Barrels AR10 Creedmoor Button Rifled Barrel Features The Bsf Barrels AR10 Creedmoor Button Rifled Barrel starts with a turned-down 416R stainless steel match barrel then wraps it in carbon fiber under tension rather than simply wrapping the exterior. This jacketing method avoids the heat trapping and delamination that affects barrels wrapped the conventional way since the carbon fiber is specially engineered to expand at the same rate as the stainless steel beneath it. Machined slots in the carbon fiber let air move around the barrel to vent heat faster during sustained fire. Keeping the barrel under tension as it heats also helps the rifling stay straighter preserving accuracy shot after shot. A 1 in 7.5 inch twist rate and button rifled construction with 6 grooves are built to stabilize 6mm Creedmoor projectiles at extended range. The 5/8x24 thread pattern accepts a wide range of muzzle devices for shooters who want to add a brake or suppressor. This carbon fiber jacketing keeps the barrel extremely lightweight while maintaining the stiffness and strength of a solid stainless barrel a real advantage for anyone carrying a precision rifle over distance. Built for AR10 platform rifles the Bsf Barrels AR10 Creedmoor Button Rifled Barrel is for sale at GrabAGun for long-range shooters seeking reduced weight without sacrificing accuracy.
