The CDX-MC KRAKEN is a multi-caliber rifle using an innovative patented 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 fast conversion between short and long action calibers. Maintaining the same P.O.I. is critical at extreme ranges and the Kraken surpasses any other multi-caliber system on the market.
