Proof Research has “Cracked The Code” on Carbon fiber wrapped barrels. Their process produces barrels that: are much lighter than steel contours, are stiffer and have less in unison vibration than steel; dissolve heat more quickly than steel resulting in maintained accuracy, over longer sessions of fire and longer barrel life. With all these benefits, they are also as accurate as the finest precision steel barrels.
Lightweight: Up to 64% lighter than normal steel barrels of similar contour.
Extreme Temperature Resistance: Removed excess heat for cooler and longer lasting barrels.
Unprecedented Durability: Wrapped with high-strength, aerospace-grade carbon fiber saturated with matrix resin.
Carbon fiber has long been hailed across many industrie. 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. Carbon fiber also moves heat completely through the wall (thickness) of the barrel greatly increasing heat transport resulting in barrels that cool faster. To maintain accuracy over longer sessions of fire, and live longer. The end result is an aerospace-grade. The high-fiber content composite barrel that is stronger, lighter, and as accurate as the finest precision steel barrel, and durable to perform in harsh environments. They’re not just lighter—they’re better.
With PROOF’s carbon fiber barrel, you are getting that rigidity that you don’t normally get in other brand’s featherweight rifles. The barrel gets hot, the carbon fiber expands and this makes the barrel more rigid and stiff. The stiffer the barrel, the better the accuracy.
Accuracy in a lightweight barrel is great, but I also want repeatability.
Proof Research has figured out how to get the whole barrel system to run from small frame to large frame.
