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

Overview

The BSF Barrels AR-15 carbon fiber barrel in 300 AAC Blackout features an 8-inch length and a 1:8 twist rate. Engineered for efficiency and accuracy, this barrel features a 416R stainless steel match core jacketed in a roll-wrapped carbon fiber sleeve under tension. Designed so that 95% of the carbon fiber does not touch the stainless steel, it forms air gaps that allow heat to vent rapidly and prevent delamination issues. The carbon fiber is formulated to match the expansion rate of 416R stainless steel, maintaining superior stiffness, strength, and lightweight handling while providing a vibration-dampening effect for more consistent shot groups. Additional features include an 11-degree target crown, 6-groove button rifling, and a double stress-relieved profile.
