Match-grade .308 AR carbon fiber barrels from BSF are built with meticulous attention to detail to ensure you’ll achieve the best possible accuracy - without getting a hernia hauling your rifle to the range! Like all BSF barrels, .308 AR pattern barrels are turned from ordnance-grade 416R stainless steel, then roll-wrapped with a tensioned, carbon fiber sleeve. The sleeve keeps weight down while providing excellent rigidity, plus enhanced cooling. BSF uses this sleeve method on their .308 AR barrels rather than simple carbon fiber wrapping because they believe wrapping traps heat, which increases the risk of delamination. Further, BSF uses a special carbon fiber that expands at the same rate as the 416R, and holes drilled into the jacket allow air to circulate around the barrel and vent heat quickly. Less heat distortion means far less risk of accuracy fade as your .308-chambered AR’s barrel heats up.
