Proof Research engineered this carbon fiber barrel using full-profile, match-grade 416R stainless steel barrel blanks wrapped in high-strength, aerospace-grade carbon fiber. The carbon fiber is impregnated with a proprietary matrix resin developed by Proof Research ACD, allowing the carbon fibers to diffuse heat effectively through the barrel wall and greatly increase heat transport. The result is an aerospace-grade composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and durable in the most demanding environments.
This 24-inch barrel is chambered in .264 Winchester Magnum with a 1:8″ twist rate and features the Sendero Light contour. The barrel weighs just 3 pounds 2 ounces—up to 64% lighter than traditional steel barrels of similar contour. It delivers match-grade accuracy and exhibits improved heat dissipation for cooler, longer-lasting barrels with no point-of-impact shift during high-volume fire.
The barrel arrives ready for thread and chamber by your gunsmith. this Proof Research barrel combines lightweight performance with proven reliability to meet the demands of serious shooters.
