Carbon Fiber Perfected

The Science

It Starts in the lab

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.

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 maintains its accuracy in the most demanding environments.
It’s carbon fiber perfected.

Advanced Carbon Fiber

Accuracy, Durability, Longevity.

The aerospace-grade carbon fiber we use has a specific strength up to 30 times that of stainless steel and a specific stiffness up to 7 times greater than steel. But strength and stiffness are only part of the equation. Heat conductivity and thermal expansion are also of paramount importance when developing a match-grade carbon fiber barrel. Our helical wrapping pattern favors the longitudinal thermal diffusivity of the carbon fibers (along the length of the barrel) allowing them to more efficiently dissipate heat emanating from the barrel, rather than insulating it.

Because our barrels are engineered for thermal performance, they also move heat very effectively through the wall (thickness) of the barrel, greatly increasing heat transport and resulting in barrels that cool faster, live longer, and maintain accuracy over longer sessions of fire.

Rigorous field testing

At PROOF Research we believe that every rifle or barrel we produce should perform flawlessly, shot after shot, in the most challenging environments. To that end, we’ve assembled a dedicated team of hunters and professional marksmen who rigorously test our products in the field and in the competitive arena. These are the men and women who faithfully represent our brand, prove our current products, and drive exciting new innovations.
