About this rifle barrel
Proof Research Zermatt TL3/SR3 Pre-fit Carbon Fiber 7MM Backcountry Rifle Barre is a rifle barrel for Zermatt|TL, 20 in, 1-8 twist, 5/8-24 threads.
Match the barrel to your platform (gas system length, barrel extension and thread pitch on an AR; the exact action on a bolt gun). Twist rate decides which bullet weights stabilize: faster twists suit heavier bullets.
Manufacturer details
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's 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 our advanced composites division, PROOF Research ACD.
The carbon fibers they 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 (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.
