At PROOF Research, we fuse advanced aerospace materials with precision engineering to create match-grade carbon fiber barrels that are lighter, stronger, and every bit as accurate as traditional steel.
Each begins with our in-house 416R stainless blank, precision-turned and wrapped in aerospace-grade carbon fiber using our patented process. The result: uncompromising performance and consistency in any environment.
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.
In addition to providing R&D support for the development of PROOF Research’s next-generation carbon fiber barrel and composite weapon technologies, PROOF Research’s Advanced Composite Division (Dayton, Ohio) also develops and supplies high-temperature products and solutions to customers within the aerospace and defense industries, including the F-35 Joint Strike Fighter and the B2 Stealth Bomber systems.
PROOF Research’s Advanced Composite Division product portfolio includes state-of-the-art structural polyimide and organic-inorganic resins, prepregs and adhesives with service temperatures up to 1500°F.
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.
