Proof Research Sig Sauer Cross Carbon Fiber Prefit Barrel 22 Creedmoor 20" 1:8" Twist 5 Groove

Overview

The Proof Research pre-fit carbon fiber barrel is engineered for the SIG Sauer Cross rifle, featuring a 20-inch barrel length, .22 Creedmoor caliber, 1:8 twist rate, and 5-groove rifling. Designed for seamless installation with an included barrel extension, the barrel is wrapped in aerospace-grade carbon fiber impregnated with a proprietary matrix resin, offering up to a 64% weight reduction compared to traditional steel contours without compromising accuracy. The helical wrapping pattern improves longitudinal thermal diffusivity and heat dissipation across the barrel wall, resulting in cooler operating temperatures and consistent match-grade accuracy during extended firing sessions.
