Proof Research 22LR CZ 455/457 Carbon Fiber Pre-Fit Barrel

You will love the Proof Research 22LR CZ 455/457 Carbon Fiber Pre-Fit Barrel if you are a fan of the CZ 455/457 22LR. The barrel is available in several lengths, and has a 16 twist rate and a Bull contour. Proof’s pre-fit CZ barrels will arrive threaded/chambered and ready for an easy install.

Why Carbon Fiber?

Carbon fiber has long been hailed across many industries such as aerospace, cycling, alternative energy. It is recognized as a wonder material that makes everything lighter and stronger. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. The Proof Research 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. This Resin is developed by Proof Research’s advanced composites division, PROOF Research ACD.

The carbon fibers that Proof Research 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 of the barrel increasing heat transport resulting in barrels that cool faster, maintain accuracy over longer sessions of fire, and live longer. The end result is an a 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.
