This mount is made specifically for the CZ 550 and 602 Magnum Action. This is for the 19mm dovetail guns. Will not fit Left Hand gun. Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. Our one-piece scope mounts are the obvious choice for hunters. This mount is a Picatinny-style base and compatible with Picatinny or Weaver scope rings. We machine these in our shop using one of our machining centers. After machining, the mounts are tumbled, sand blasted, and Type III anodized for long lasting durability.
