Proof Research 300 Win Mag Terminus Pre-Fit Carbon Fiber Barrel

Proof Research 300 Win Mag Terminus Pre-Fit Carbon Fiber Barrel makes it easy to upgrade your current rifle. The carbon fiber and steel pre-fit barrels for the Terminus Apollo, Zeus and Kratos actions come chambered and threaded for an easy install. Simply torque on, double check and ensure headspace with proper gauges and head to the range. Proof’s pre-fit Terminus barrels are a relatively easy install with no specialized gunsmithing required.

The Proof Research  Carbon Fiber Barrels are much lighter, more durable, and accurate than traditional barrels. Proof Research make these Rifle Barrels starting with full profile, match grade 416R stainless steel barrel blanks that are then turned down to a significantly reduce it’s weight. The Proof Research barrels are then wrapped with high strength, aerospace grade carbon fiber. 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. They’re not just lighter, they’re better.

Why Carbon Fiber?

Carbon fiber has long been hailed across many industries such as aerospace, cycling, alternative energy. 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 our 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.
