Proof Research Carbon Fiber Barrel 6.5 Grendel 18 Barrel

Carbon Fiber Barrel Features 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. Our patented manufacturing process begins with full-profile match-grade 416R stainless steel barrel blanks that are made in our 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 division PROOF Research ACD. The carbon fibers we use have a unique ability to diffuse heat along the length of the barrel (much like fiber optics transmit light). Carbon fiber also moves heat very effectively through the wall (thickness) of the barrel greatly increasing heat transport resulting in barrels that cool faster maintain accuracy over longer sessions of fire and live longer. The end result is an aerospace-grade high-fiber content composite barrel that is stronger lighter as accurate as the finest precision steel barrel and durable to perform in the most demanding environments. They're not just lighter-they're better.
