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

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.

This 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 filament-wrapped with high-strength, aerospace-grade carbon fibers impregnated with a high-thermal conductivity matrix resin developed by our aerospace materials division.

The JP Enterprises Enhanced Bolts™ are the perfect add-on to your new Proof Research AR Barrel.  The JP Enhanced Bolts™ have become the industry's go-to bolt assembly. Made out of Superior SAE 9310 material, these bolts have an extended life span and resiliency unlike any other bolt on the market today. Stocky's® is carrying a variety of different caliber bolt assemblies. 

When PROOF Research joined with Lawrence Barrels in 2012 they acquired 15 years of experience in manufacturing precision steel barrels. These stainless steel cut-rifled 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.
