AR-15 22 ARC 22" Standard 1-7 Twist Carbon Fiber Barrel

Carbon fiber has long been hailed across many industries-aerospace, cycling, alternative energy-as a wonder material making everything lighter and stronger. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. Proof's patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made in their firearms division. These blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by our advanced composites di Mfg: Proof Research
