Proof Research 300 Win Mag Zermatt Arms Pre-Fit Carbon Fiber Barrels

Proof Research 300 Win Mag Zermatt Arms Pre-Fit Carbon Fiber Barrels was designed for Zermatt Arms TL3 and SR3 actions. The barrel makes it easy to upgrade your rifle or change calibers. Their pre-fit Zermatt Arms  TL3/SR3 shouldered barrels are easy to install. NO GUNSMITH REQUIRED—Just thread it on, torque it down, and head for the range. Barrels are specific to the action type/length and are not interchangeable.

Proof Research Carbon Fiber Rifle Barrel is much lighter, more durable, and accurate than traditional barrels. These barrels will fit into your Zermatt Arms Rifle. Carbon fiber not only reduces barrel weight by 50% or more but also increases the overall durability.  The result is a recoil impulse that is noticeably softer, less fouling in the receiver, increased reliability of extraction, and less wear and tear on brass. This helps keep you on target and shooting while taking advantage of the latest high performance cartridges.

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.

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.
