- Excellent machinability for gun drilling and reaming, plus exceptional polishability for uniform lapping
- A homogeneous microstructure which responds to heat treatment providing a uniform hardness along the length of the barrel
- An optimum combination of high tensile strength along with requisite toughness to withstand extreme chamber pressures encountered during firing
- Excellent erosion wear characteristics and corrosion resistance
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.
At PROOF Research we meld our unique manufacturing process with next-generation aerospace materials and thermo-mechanical design principles to create a truly innovative product—match-grade carbon fiber barrels that weigh a fraction of traditional steel barrels while compromising nothing.
Our patented manufacturing process begins with 416R stainless steel barrel blanks manufactured in-house. These blanks are then turned to a significantly reduced profile to greatly reduce 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.
