Egw Cz 457 11Mm 1-Piece Picatinny Base 0 Moa

The EGW CZ 457 11mm 1-piece Picatinny base in 0 MOA is a precision scope mount engineered for shooters running CZ 457 rifles who need a solid, repeatable platform for optics mounting. Unlike separate two-piece bases, a one-piece design eliminates potential alignment issues and delivers the kind of rock-solid foundation that matters when you're dialing in for accuracy. This mount uses full-length Picatinny cross slots, giving you flexibility to position scope rings exactly where you want them and to add auxiliary accessories without compromise.

EGW machines these bases in-house using CNC equipment, then tumbles, sand blasts, and applies Type III hard anodize for a durable finish that handles field use and recoil without degradation. The 0 MOA configuration is the right choice if your shooting distance stays in the 0–500 yard range—think hunting, range work, or precision rifle practice at typical hunting distances. If you're stretching shots beyond 500 yards, EGW offers a 20 MOA variant to simplify elevation adjustments. Everything here—base, mounting screws, and even the included wrench—is made in the USA.

Installation is straightforward: EGW recommends 20 inch-pounds of torque on the fasteners and a drop of blue Loctite to keep things locked in place (Loctite sold separately). The mount accepts any Picatinny or Weaver scope rings, so you're not locked into a single ring manufacturer. If you're building or upgrading a CZ 457 and want a dependable, American-made mounting solution that doesn't reinvent the wheel, this is a solid choice.

Frequently Asked Questions

What is the difference between the 0 MOA and 20 MOA bases?

The 0 MOA base is designed for shooting distances from 0 to 500 yards and keeps the mount parallel to the bore. The 20 MOA version tilts the rail upward by 20 minutes of angle to simplify elevation turret adjustments for longer-range shooting (500–1000 yards). Choose based on your typical shooting range.

Will this mount work with any Picatinny or Weaver scope rings?

Yes. The EGW base accepts both Picatinny and Weaver scope rings, so you have flexibility in choosing your rings based on preference or inventory.

What tools and supplies do I need to install this mount?

EGW supplies a wrench with the mount. You'll also need a torque wrench set to 20 inch-pounds and blue Loctite threadlocker (sold separately) to secure the fasteners. Avoid over-torquing, which can damage the CZ 457 receiver.

Is this mount made in the USA?

Yes. EGW manufactures this mount in their shop using CNC machinery, and all fasteners, accessories, and packaging are also made in the USA.
