Carbon fiber is a highly praised material that offers benefits in various industries such as aerospace, cycling, and alternative energy. When used in rifle barrels, it not only reduces weight but enhances strength and accuracy. A unique patented manufacturing process by Proof involves starting with highly-efficient 416R stainless steel barrel blanks. These blanks undergo a reduction in profile to decrease weight before being enveloped with aerospace standard, carbon fiber of exceptional strength, integrated with a distinctive PROOF Research ACD composite resin. The carbon fiber has extensive heat diffusion abilities along the length of the barrel and moves heat proficiently through the barrel's wall thickness as well. This feature allows for faster cooling of the barrel and the ability to maintain precision over a more extended period of shooting, increased durability in the most challenging environments, and a payload of other benefits. The final product is a stronger, lighter, and highly precise aerospace quality carbon fiber barrel, which elevates the overall rifle experience.
