Carbon fiber is a versatile material that has been praised across many industries such as aerospace, cycling, and alternative energy for being incredibly lightweight and strong. When applied to rifle barrels, carbon fiber's benefits go beyond weight reduction and enhanced strength. Proof, a firearms company, uses their patented manufacturing process to create a high-strength barrel. Their process begins by using 416R stainless steel, which they turn down to a smaller profile to reduce weight. Afterwards, Prood Research ACD, their advanced composites division, wraps a proprietary matrix resin around the barrel using aerospace-grade carbon fiber. This carbon fiber is unique because it has a special ability to disperse heat along the length of the barrel, similar to how fiber optics transmit light. Additionally, carbon fiber effectively dissipates heat through the barrel wall, greatly boosting heat transport, resulting in a more accurate and longer-lasting barrel. The final result generates aerospace-grade, high-fiber content composite barrels that are superior in durability, as accurate as the finest precision steel barrel, and, of course lighter.
