BSF Barrels AR-15 Barrel 300 AAC Blackout 14.5" 1:8 Twist Carbon Fiber

Overview

The BSF Barrels AR-15 barrel is chambered in 300 AAC Blackout with a 14.5-inch length and a 1:8 twist rate. It features a unique carbon fiber construction designed to maximize stiffness, strength, and vibration dampening while keeping the assembly extremely lightweight. BSF jackets a 416R stainless steel match barrel inside a roll-wrapped carbon fiber sleeve and loads it under tension, leaving 95 percent of the carbon fiber not touching the stainless steel. This creates air gaps that allow air to flow and vent heat quickly without delamination issues. Additional features include an 11-degree target crown, 6-groove button rifling, and double stress-relieving.
