Egw Cz 557 Sa 1-Piece Picatinny Base 0 Moa

The EGW CZ 557 Short Action one-piece Picatinny base is a precision-engineered scope mount built for hunters and shooters who demand solid, repeatable accuracy. Machined in-house and finished with Type III hard-coat anodization, this 0 MOA base delivers the rugged durability you need in the field. The full-length Picatinny rail accepts any standard Picatinny or Weaver rings, giving you flexibility to choose the optic setup that works best for your rifle and shooting style.

Built specifically for the CZ 557 Short Action platform, this one-piece design eliminates the shift and flex of two-piece mounts. The 0 MOA configuration is ideal for shooters working targets out to 500 yards—the sweet spot for most hunting scenarios where elevation is managed through your scope's turrets. EGW machines every base on CNC equipment, then tumbles and sand-blasts before anodizing for a finish that shrugs off weather and hard use. Everything from the mounting screws to the wrench is made in the USA, so you're supporting domestic manufacturing and getting parts backed by real expertise.

Installation is straightforward: apply 20 inch-pounds of torque to the factory action screws and lock them in place with a drop of blue Loctite (sold separately). EGW recommends confirming your rifle's ejection port opening measures 2.675 inches before ordering, as some short-action CZ rifles can have slightly longer ports. Once mounted and zeroed, you'll have a solid platform that won't shift between sessions.
