The Proof Research Defiance Ruckus Carbon Pre-Fit Barrel, 6.5 CM, 22" Threaded Sendero Contour is a lightweight, precision bolt-action barrel built for shooters who want carbon fiber performance with straightforward installation. This pre-fit design comes chambered in 6.5 Creedmoor with a 22 inch length, 1-in-8 twist, and 5/8-24 threaded muzzle, making it ready for brakes or suppressors while maintaining a rigid, consistent bore and excellent stability for modern long-range loads.

This barrel is ideal for long-range target shooting, practical competition, and hunting where accuracy and reduced carry weight matter. The Sendero contour balances stiffness and handling, while the carbon fiber wrap improves heat dissipation for cooler, longer shooting strings. Designed specifically to fit Defiance Ruckus actions with the recessed bolt nose option, it offers a true drop-in solution that reflects Proof Research’s reputation for innovation and high-end craftsmanship in precision rifle components.
