The EGW 1-Piece Picatinny Base for the CZ 557 (short action) (EGW part no. 80926) is a one-piece scope base that spans the full length of the receiver and builds in 20 MOA of forward cant, extending the scope’s usable elevation range for long-distance shooting. Machined specifically for this rifle rather than sold as a generic universal base, it registers directly to the receiver’s factory screw pattern for a repeatable, no-slop fit. A one-piece design is stiffer than separate two-piece bases, which keeps your scope’s zero from shifting under recoil. This base gives hunters and precision shooters running the CZ 557 a standard Picatinny interface for mounting rings, scopes, or night-vision optics.
