The EGW HD CZ 457 20 MOA Picatinny Scope Base (EGW part no. 80932) adds a canted one-piece rail to the CZ 457 for long-range rimfire work. The built-in 20 MOA cant preserves the scope’s internal adjustment so you can dial for distant targets without bottoming out the turret, which matters in disciplines like NRL22. EGW CNC-machines each base from solid 7075-T6 aluminum and finishes it in matte black hardcoat anodize. It is designed exclusively for the CZ 457 receiver.

Key Specifications

• The mount is made for the CZ 457 (all models), so it matches that receiver instead of a generic pattern.
• Built-in elevation is 20 MOA, which sets how the optic sits relative to the bore.
• It is machined from solid 7075-T6 aircraft-grade aluminum, which keeps the mount strong without adding bulk.
• The finish is matte black hardcoat anodize, a coating that protects the aluminum from scratches and wear.
• Overall length is 6.276 inches, which sets how much rail is available for ring placement.
• Height is 0.540 inch from the top of the receiver to the top of the Picatinny rail.
• It weighs 4.6 ounces, so it adds almost nothing to the rifle.
• Quick-disconnect rings are compatible, if you want to remove the optic and return to zero.
• The mount is not ambidextrous, contoured for the standard side of the receiver.
• Included mounting hardware is #6-32 x 3/4 socket head screws and a T-10 bit, so installation needs nothing extra.

Frequently Asked Questions

Does the 20 MOA cant fit a 0 MOA scope setup? The 20 MOA cant preserves the scope’s internal elevation travel, so it is meant for shooting at distance. If you mostly shoot close targets, EGW also offers this CZ 457 base in 0 MOA.

Will it fit a CZ 455 or 452? No. EGW designed this mount for the CZ 457 receiver only. The CZ 455 and 452 have different receiver contours and hole spacing.

What do I need to install it? The base ships with #6-32 x 3/4 socket head screws and a T-10 bit, with a specified torque of 20 inch-pounds.
