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. Proof carbon fibers 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.

  • Up to 64% lighter than traditional steel barrels of similar contour
  • Match-grade accuracy
  • Improved heat dissipation for cooler and longer-lasting barrels
  • Reduced harmonic barrel vibration
  • Unprecedented durability
