BSF Barrels AR-10 .308 Win 20" 1:10 Carbon Fiber Barrel

Bsf Barrels AR-10 Win Barrel Features The Bsf Barrels AR-10 Win Barrel starts as a turned down 416R stainless steel match barrel which is then jacketed in a roll-wrapped carbon fiber sleeve loaded under tension rather than simply wrapped around the barrel. This tensioned jacketing method avoids the heat trapping and delamination problems that come with conventional carbon fiber wraps so the barrel holds up to repeated strings of fire. The carbon fiber itself is engineered to expand at the same rate as the 416R stainless steel underneath which means the two materials move together as the barrel heats up instead of working against each other. Machined slots in the jacket let air move around the barrel to vent heat quickly keeping rifling straighter even as the barrel warms during extended shooting sessions. Built with a 1:10 inch twist rate over a 20 inch button rifled bore this barrel suits .308 Win loads across a wide range of bullet weights for AR-10 platform rifles. Because the carbon fiber jacket is under tension the barrel keeps its stiffness and strength while weighing considerably less than a comparable solid steel barrel reducing the overall weight of the rifle. A 5/8x24 thread pattern on the muzzle end accepts standard compensators flash hiders and suppressor mounts for AR-10 pattern rifles. This 20 inch stainless and carbon fiber barrel is available for sale at ARMSAGORA for shooters building a lightweight heat tolerant AR-10 rifle for precision or duty use.
