BSF Barrels AR-10 Barrel 204 Ruger 20" 1:12 Twist Carbon Fiber

Overview

The BSF Barrels AR-10 Barrel is chambered in .204 Ruger with a 20-inch length and a 1:12 twist rate, finished in carbon fiber. BSF utilizes a specialized manufacturing method by jacketing a 416R stainless steel match barrel inside a roll-wrapped carbon fiber sleeve loaded under tension. This design leaves air gaps across most of the carbon fiber to allow air to circulate and vent heat more rapidly without delamination issues, while utilizing carbon fiber engineered to match the expansion rate of 416R stainless steel. Machined openings in the carbon fiber further assist in heat dissipation while maintaining barrel stiffness, strength, and a lightweight profile. The carbon sleeve also provides a vibration dampening effect to absorb shock and maintain straighter rifling as the barrel warms up. Additional features include an 11-degree target crown, 6-groove button rifling, and a double stress-relieved build.
