The Science

At the heart of our company is our patented process for creating state-of-the-art carbon fiber-wrapped barrels. By combining our unique manufacturing process with novel, aerospace materials and thermo-mechanical design principles, we’ve created a truly innovative product—match-grade carbon fiber barrels that weigh a fraction of traditional steel barrels while compromising nothing.

At PROOF Research we’re proving that carbon fiber-wrapped barrels aren’t just a lightweight alternative to traditional steel barrels, but that they provide superior performance, including increased accuracy, durability and barrel life. They’re not just lighter—they’re better.

Our patented manufacturing process begins with match-grade 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 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 and maintain accuracy over longer sessions of fire.

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.

PROOF Research’s match-grade carbon fiber barrels are stronger, lighter, as accurate as the finest precision steel barrels and will maintain their performance in the harshest conditions.

  • Up to 64% lighter than traditional steel barrels
  • Match-grade accuracy
  • Improved heat dissipation for cooler and longer lasting barrels
  • No point-of-impact shift during high-volume fire
  • Reduced harmonic barrel vibration
  • Unprecedented durability
