Proof Research 308 WIN Carbon Fiber Button Barrel
This Proof Research 308 WIN Carbon Fiber button barrel is 18″ in length, has a twist rate of 10 and a 5/8-24 muzzle thread. It features a rifle gas system length and a .815 gas journal diameter. It is compatible with any AR10 DMPS pattern upper, and can only be used with the (savage style) gas block and tube provided.
Why Carbon Fiber?
Carbon fiber has long been hailed across many industries such as aerospace, cycling, alternative energy. It is recognized as a wonder material that makes everything lighter and stronger. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. The Proof Research 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. This Resin is developed by our advanced composites division, PROOF Research ACD.
The carbon fibers that Proof Research 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 of the barrel increasing heat transport resulting in barrels that cool faster, maintain accuracy over longer sessions of fire, and live longer. The end result is an a 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.
