BSF Barrels AR-15 .338 ARC Threaded AR Barrel

BSF Barrels AR-15 .338 ARC Threaded AR Barrel. This barrel uses a 416R stainless steel match barrel jacketed with a roll-wrapped carbon fiber sleeve. The carbon fiber is designed to move at the same expansion rate as the stainless steel and is machined with slots to vent heat and prevent delamination. The result is improved stiffness and strength while keeping the barrel lightweight. Available in multiple lengths with 1/2x28 threads and a 1-8 twist.
