BSF Barrels Carbon Fiber AR-15 .338 ARC 16" 1:8 Barrel

BSF Barrels AR-15 Barrel Features The Bsf Barrels Carbon Fiber Barrel begins 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. This method is chosen because traditional carbon fiber wrapping has been shown to trap heat and lead to delamination over repeated use. The carbon fiber itself is engineered to expand at the same rate as the 416R stainless steel beneath it keeping the two materials moving together as temperatures rise. Machined slots in the carbon fiber let air circulate around the barrel venting heat quickly without compromising the integrity of the wrap. Because the carbon sleeve is under tension the barrel keeps its rifling straighter even as it heats up during sustained firing helping maintain accuracy across longer strings. This jacketing method also produces a notably lighter barrel than an all-steel equivalent which is especially valuable on an AR-15 platform chambered in the harder-hitting .338 ARC cartridge. At 16 inches with a 1:8 twist button rifled construction and a 5/8x24 thread pattern this barrel is built to handle the demands of .338 ARC shooting.
