Proof Research Kelbly's Atlas Prefit Barrel 7 PRC 26" Stainless Heavy Competition 1:8" Twist 5 Groove

Overview

The Proof Research Kelbly's Atlas prefit barrel is chambered in 7 PRC with a 26-inch length, heavy competition contour, and a 1:8-inch twist rate. The barrel is produced in-house from double-stress relieved 416R stainless steel that is drilled, contoured, reamed, cut-rifled, and lapped to match-grade standards. It is inspected via borescope to ensure consistent accuracy and durability. This barrel utilizes an aerospace-grade carbon fiber wrap applied in a helical pattern, which enhances thermal conductivity and longitudinal thermal diffusivity. This design allows the barrel to dissipate heat more efficiently than standard steel barrels, helping to maintain accuracy during extended firing sessions.
