All Rimfire Barrels

"PROOF has cracked the code with high-performance carbon-fiber barrels.” - Outdoor Life Magazine

Less than half the weight of comparably-sized steel barrels. (Finished weight under 2 lbs.)

PROOF Research is proving carbon fiber-wrapped 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.

These stainless steel barrels are made in-house with an absolute commitment to extreme accuracy and quality. They start with double stress-relieved 416R stainless steel, a pre-hardened chromium stainless steel ideally suited for use in precision, match-grade rifle barrels. 416R was specifically designed by engineers in collaboration with barrel makers and rifle manufacturers to provide the consistency, high quality and durability the firearms industry demands.

416R is our stainless steel of choice because it has the following characteristics:

• Excellent machinability for gun drilling and reaming, plus exceptional polishability for uniform lapping—a must for bore accuracy.
• A homogeneous microstructure which responds to heat treatment providing a uniform hardness along the length of the bar, necessary for accurate rifling to precise groove dimensions.
• An optimum combination of high tensile strength along with adequate toughness to withstand typical chamber pressures encountered during firing.

The same quality and reliability you have come to expect from our 10/22® barrels are also available for the Charger™ Pistol from Ruger®. Pricing: Same as 10/22® Barrels Rifling: 6 groove, 1 in 16 for .22 lr. a .920 outside diameter, 11° Target Crown 14" - 19 oz. Please check local laws for legality purposes. WARNING: These barrels are to be used on .22 Charger™ Pistols ONLY. Installation of one of these barrels on a 10/22® rifle receiver would constitute a violation of federal law. All N.F.A rules apply.
