Why Choose the EGW HD 20 MOA Mount for Your CZ 457?
The CZ 457 is a world-class rimfire rifle. Our HD 20 MOA rail is engineered to provide the most stable optics platform for long-range performance, making it the best scope mount for the CZ 457 in disciplines like NRL22. Key features include:
Built-In 20 MOA Cant: Preserves your scope's internal adjustment, allowing you to dial for distant targets without bottoming out your turret.
Machined from Billet 7075 T6 Aluminum: We CNC-machine each mount from a solid block of American-sourced, aerospace-grade 7075 T6 aluminum. This provides the strength of steel at a fraction of the weight, ensuring maximum rigidity.
Perfect, Action-Specific Fit: This base is designed exclusively for the CZ 457 receiver, ensuring a no-gap, stress-free fit for the highest level of precision.
Full-Length Picatinny Slots: MIL-STD-1913 Picatinny cross slots run the full length of the rail, allowing you to mount your scope rings at any position for perfect eye relief.
Made in the USA: Precision-crafted in our shop and backed by a lifetime of service.

Frequently Asked Questions
When do I need a 20 MOA scope mount?
A 20 MOA mount is the perfect choice for shooters looking to engage targets at extended rimfire distances (typically 150-300 yards). The built-in angle gives your scope more usable "up" elevation, which is critical for .22LR ballistics at long range.
Why is a Picatinny rail better than the factory 11mm dovetail?
While the factory 11mm dovetail is functional, a one-piece Picatinny rail provides a much more stable and versatile platform. It prevents any potential for scope ring misalignment and allows you to use a far wider variety of robust, readily available Picatinny and Weaver-style rings, which are the standard in competition.
Will this mount fit my CZ 455 or 452?
No. This mount is designed specifically for the CZ 457 receiver. The CZ 455 and 452 have different receiver contours and hole spacings. Please see our dedicated CZ category page to find the correct mount for your rifle.
