MDT Picatinny Scope Base Features The MDT Picatinny Scope Base for the CZ 457 is machined from 6061-T6 aluminum and finished with a durable mil-spec Type III hard-anodized black coating that resists wear and corrosion. Cut to MIL-STD-1913 and STANAG 4694 rail specifications it provides a consistent mounting surface for standard Picatinny rings and scope mounts. A built-in incline elevation cant gives the shooter additional scope adjustment range for dialing in long-range shots without maxing out the optic s internal elevation travel. The underside is profiled to fit flush against the CZ 457 receiver and matches the contour of the ejection port for a clean gap-free installation. An integrated recoil lug is machined into the underside of the base on compatible actions helping the rail stay precisely located and preventing stress on the mounting screws from repeated recoil. The rail is contoured along its edges to prevent snagging on gear or clothing during handling and transport. Mounting hardware is included with every base so installation requires no additional purchases beyond a scope and rings. This combination of a rigid aluminum build elevation cant and CZ 457-specific fit makes the base a practical upgrade for shooters extending their rimfire rifle s effective long-range capability.
