proof research - carbon fibre match barrels

PROOF Research barrels are  proving carbon fiber-wrapped barrels. These new barrels aren’t just a lightweight alternative to traditional steel barrels, but that they provide superior performance, including extreme accuracy, unprecedented durability and increased barrel life. By combining our unique manufacturing process with advanced technology composite materials and thermo-mechanical design principles, we’ve accomplished what others have failed to do in the past—match-grade carbon fiber barrels that weigh a fraction of traditional steel barrels while compromising nothing. They’re not just lighter—they’re better.

The 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 fibre impregnated with a proprietary matrix resin developed by our advanced composites division, PROOF Research ACD.


The aerospace-grade carbon fibre we use has a specific strength up to 30 times that of stainless steel and a specific stiffness up to 7 times greater than steel. But strength and stiffness are only part of the equation. Heat conductivity and thermal expansion are also of paramount importance when developing a match-grade carbon fibre barrel. Our helical wrapping pattern favours the longitudinal thermal diffusivity of the carbon fibres (along the length of the barrel) allowing them to more efficiently dissipate heat emanating from the barrel rather than insulating it.

Because Proof barrels are engineered for thermal performance they also move heat very effectively through the wall (thickness) of the barrel, greatly increasing heat transport and resulting in barrels that cool faster and maintain accuracy over longer sessions of fire.


The end result is an aerospace-grade, high-firer content composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and maintains its accuracy in the most demanding environments.


We didn’t invent carbon fibre-wrapped barrels. We just perfected them.

Rifle Barrel Fluting

Interrupted and spiral fluting to any style, depth or length/depth of flutes also available.

Available Chamber Reamer List


We currently have over 30 Full Reamer sets in stock and are adding to this on a regular basis, so If we don’t have the Chamber Reamer for your Calibre, please give us a ring and we will order it from Pacific. There is no extra charge for buying in a Chamber Reamer. All Chamber Reamer sets include Roughing, Resize and Finish Reamer plus all Gauges, Indicator Rods and Throating Reamers. All our Reamers are minimum Freebore (throat length) and we use a sep throating reamer to enable us to cut the throat length to the customers requirements and his ammunition type.
