BSF 8.6 Blackout, 1:3 Twist, 12″ Carbon Fiber Roll-Wrapped AR-10 Barrel

This product is a BSF carbon fiber roll-wrapped 12″ AR-10 barrel chambered in 8.6 Blackout with a 1:3 Twist. After turning down the barrel, BSF jacket a 416R Stainless steel match barrel in a roll-wrapped carbon fiber sleeve and load it under tension. They use this jacketing method rather than wrapping the barrel in carbon fiber because this method of wrapping has been proven to trap heat and cause delamination. The carbon fiber they use is specially designed to move at the same expansion rate as 416R stainless steel.

• 6 Groove Button Refiling
