PROOF RESEARCH Sendero Pre-Fit Barrel .308 Win 20" Fits Zermatt Arms Origin

Discover the next evolution in firearm technology. Carbon fiber rifle barrels from PROOF Research revolutionize the industry, leveraging the "wonder material" acclaimed in aerospace and alternative energy for its superior strength-to-weight ratio. PROOF's patented process begins with high-precision, match-grade 416R stainless steel barrel blanks, manufactured in-house. These blanks are meticulously contoured to significantly reduce weight before being wrapped with high-strength, aerospace-grade carbon fiber integrated with a proprietary matrix resin. This advanced composite not only makes the barrel lighter and stronger, but the unique properties of the carbon fiber also enhance heat dissipation-diffusing heat along the barrel and moving it effectively through the wall. This results in barrels that cool faster, maintain greater accuracy over extended firing sessions, and offer a longer lifespan. For a high-fiber content composite barrel that delivers aerospace-grade precision and unmatched durability in the most demanding environments. They aren't just lighter; they're fundamentally better.
