Proof Research Zermatt Origin Carbon Fiber Prefit Barrel 25 Creedmoor 24" Sendero Contour 1:7.5" Twist

Overview

The Proof Research Zermatt Origin prefit barrel is chambered in 25 Creedmoor with a 24-inch length, a 1:7.5" twist rate, and a Sendero contour. Designed for precision rifle builds, it features a 5/8"-24 muzzle thread and weighs approximately 2 pounds, 15 ounces. Proof Research manufactures its steel cores in-house using double-stress relieved 416R stainless steel that is drilled, reamed, cut-rifled, lapped, and borescope-inspected for match-grade consistency. Encased in aerospace-grade carbon fiber utilizing an advanced helical wrapping pattern, this barrel is engineered for superior thermal diffusivity. The composite construction efficiently conducts and dissipates heat away from the bore, allowing the barrel to cool rapidly and maintain exceptional accuracy during extended strings of fire.
