BSF 6.5 Grendel 20" Carbon Fiber AR-15 Barrel 1-8 Twist

BSF 6.5 Grendel Carbon Fiber AR-15 Barrels have a match-grade 416R stainless steel inner core sleeved in roll-wrapped carbon fiber that provides superb rigidity, weight savings, and excellent cooling. Three times stronger than steel, the carbon fiber sleeve puts an air pocket between the barrel and carbon, allowing air to flow around the stainless steel inner barrel, further enhancing cooling. Vent holes in the carbon fiber sleeve lets that internal heat escape, expediting barrel cooling even more. In the end, BSF 6.5 Grendel Carbon Fiber AR-15 Barrels stay cool enough you can hold them with your bare hands, even after running 60 consecutive rounds down them! Match grade inner Mfg: Bsf Barrels
