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.

We have designed our AR barrels with the goal of improving performance and reliability in the AR platform. Our Caliber Matched Gas System (CAMGAS) results in a gas system that is tuned specifically for the cartridge and length of the barrel.

  • Our AR-10 barrels use a deep feed system that makes the feed ramps compatible with the feed ramps in the lower receivers of both DPMS and Armalite style rifles.
  • Up to 64% lighter than traditional steel barrels of similar contour
  • Match-grade accuracy
  • Improved heat dissipation for cooler and longer lasting barrels
