Proof Research Lone Peak Arms Carbon Fiber Prefit Barrel 300 PRC 24" Sendero Contour 1:9" Twist 5 Groove

Overview

The Proof Research Lone Peak Arms carbon fiber prefit barrel is chambered in .300 PRC with a 24-inch length, Sendero contour, 1:9-inch twist, and 5-groove rifling in a carbon fiber finish. Proof Research steel barrels are produced in-house from double-stress-relieved 416R stainless steel that is drilled, contoured, reamed, cut rifled, lapped, and inspected via borescope. The barrel is wrapped in aerospace-grade carbon fiber using a helical wrapping pattern that enhances longitudinal thermal diffusivity, allowing the barrel to dissipate heat efficiently, cool faster, and maintain match-grade accuracy and durability over extended firing sessions.
