BSF Barrels AR-10 .243 Winchester Threaded AR Barrel

BSF Barrels AR-10 .243 Winchester Threaded AR Barrel. This barrel is a 416R stainless steel match barrel jacketed in a roll-wrapped carbon fiber sleeve. The jacketed construction is designed to vent heat and prevent delamination, with the carbon fiber tuned to move at the same expansion rate as 416R stainless. Slots are machined into the carbon fiber to promote airflow and cooling, helping keep rifling stable as the barrel heats. Lightweight yet rigid, optimized for AR-10 platforms.
