843068134474 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. The patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made in their 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 their advanced composites division, PROOF Research ACD. The carbon fibers used 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.

The SIG SAUER CROSS Pre-Fit Drop-In Carbon Fiber .308 Win Barrel by PROOF RESEARCH revolutionizes the way you think about rifle performance. Carbon fiber, celebrated across various industries for its lightweight and strength, brings unparalleled advantages to your shooting experience.

Unmatched Strength and Performance

Utilizing a patented manufacturing process, this barrel starts with full-profile, match-grade 416R stainless steel blanks crafted in PROOF Research's firearms division. These blanks are meticulously turned down to a significantly reduced profile, achieving a remarkable reduction in weight while enhancing strength.

Advanced Heat Management

The reduced contour barrel is then expertly wrapped with high-strength, aerospace-grade carbon fiber, which is impregnated with a proprietary matrix resin developed by PROOF Research's advanced composites division, ACD. This innovative design allows the carbon fibers to diffuse heat along the barrel's length, similar to how fiber optics transmit light.

Enhanced Cooling and Durability

  • Effective heat movement through the barrel wall increases heat transport.
  • Barrels cool faster, maintaining accuracy over extended shooting sessions.
  • Durable enough to perform in the most demanding environments.

The result is an aerospace-grade, high-fiber content composite barrel that is not only stronger and lighter but also matches the precision of the finest steel barrels. The SIG SAUER CROSS Pre-Fit Drop-In Carbon Fiber .308 Win Barrel is designed to elevate your shooting experience—because they're not just lighter—they're better.
