The EGW CZ 557 Short Action 1-piece Picatinny base is a purpose-built scope mount for shooters who demand a solid, American-made foundation for their rifle optics. Whether you're hunting at moderate distances or stretching shots out to 1000 yards, this single-piece base gives you the rigid platform and elevation adjustment you need to get on target and stay there.

Built in EGW's own shop and finished with Type III hard anodizing, this mount is machined to exacting standards and built to handle the recoil and abuse of real hunting and shooting. The full-length Picatinny rail runs the entire length of the base, giving you genuine flexibility to position scope rings exactly where you need them and add accessories without compromise. The 20 MOA elevation built into the base is ideal for long-range hunting and precision shooting; if you're shooting inside 500 yards, a 0 MOA base may be a better fit for your zero. Installation is straightforward—EGW specifies 20 inch-pounds of torque and recommends blue Loctite (sold separately) to keep everything locked in place.

One important note: the CZ 557 Short Action has varying ejection port dimensions across production runs. EGW specifies that the port opening should measure 2.675 inches; if your rifle has a longer ejection port, this base may not fit properly. A quick measurement before ordering will save you headache. The mount accepts both Picatinny and Weaver scope rings, so you can use quality rings you already own or pick up exactly what works for your rifle and optic. Every component—screws, wrench, packaging—is made in the USA.
