The CDX-MC KRAKEN^®, is a multi-caliber rifle using an innovative (patent pending) barrel change system. This multi-caliber system features the lowest shift of point of impact between takedown and reassembly of the same barrel on the market. Cadex CDX-MC uses a traditional barrel to action threading system while incorporating a special tool designed to unscrew and torque its barrel from the breech side. A single screw secures the chassis detachable base for a fast conversion between short and long action calibers. Maintaining the same P.O.I. is critical at extreme range and the Kraken^® surpass any other multi-caliber system on the market.
