Proof Research Lone Peak Arms Carbon Fiber Prefit Barrel 25 Creedmoor 22" Sendero Contour 1:7.5" Twist 5 Groove

Overview

The Proof Research Lone Peak Arms Carbon Fiber Prefit Barrel is chambered in .25 Creedmoor with a 22-inch barrel length, a Sendero contour, a 1:7.5-inch twist, and 5 grooves. Produced in-house from double-stress relieved 416R stainless steel, these match-grade steel barrels are drilled, contoured, reamed, cut rifled, lapped, and borescope-inspected for exceptional consistency. The aerospace-grade carbon fiber wrap utilizes a helical pattern that enhances longitudinal thermal diffusivity, allowing the barrel to efficiently dissipate heat away from the bore. This advanced thermal engineering promotes rapid cooling through the barrel wall and maintains match-grade accuracy and durability during extended firing sessions.
