The Cadex CDX-MC Kraken Replacement Barrel allows precision shooters to rapidly convert their modular rifle chassis to the high-performance 7mm Precision Rifle Cartridge (PRC) platform. Built through an exclusive partnership with Bartlein Barrels, it features single-point cut 5R Mil-Spec match-grade rifling designed to enhance structural longevity and projectile stability. This 26-inch variant is engineered with longitudinal fluting along its exterior profile to accelerate thermal dissipation and decrease front-end handling weight. It comes factory-finished in a heavy-duty black coating to guard against field elements and comes threaded at a standard 5/8"-24 TPI pitch to host muzzle brakes or suppressors seamlessly. Optimized for field flexibility, its breech-threaded lock system works natively with the Kraken's proprietary torque chassis tool to change calibers with nearly zero shift in point of impact.
