Proof Research Elevation Carbon Fiber Prefit Barrel 300 Winchester Magnum 22" 1:10" Twist 5 Groove

Overview

The Proof Research Elevation prefit barrel is chambered in 300 Winchester Magnum with a 22-inch barrel length, a 1:10-inch twist, and 5-groove rifling. Built with a black carbon fiber finish, it is constructed from double-stress relieved 416R stainless steel produced and inspected in-house for match-grade accuracy and exceptional durability. The barrel utilizes an aerospace-grade carbon fiber wrap featuring a specialized helical pattern designed to optimize thermal diffusivity. This configuration efficiently channels heat away from the bore and through the barrel wall to promote rapid cooling and consistent precision across long strings of fire.
