Proof Research AR15 Carbon Fiber Barrel 6.8 SPC 18" Rifle .750 Gas 10T

At PROOF Research they are proving carbon fiber-wrapped barrels aren’t just a lightweight alternative to traditional steel barrels, but that they provide superior performance, including extreme accuracy, unprecedented durability and increased barrel life. By combining unique manufacturing process with advanced technology composite materials and thermo-mechanical design principles, we’ve accomplished what others have failed to do in the past—match-grade carbon fiber barrels that weigh a fraction of traditional steel barrels while compromising nothing. They’re not just lighter—they’re better.
