CZ 457 Upgrades FAQ

Why is a Picatinny rail better than the factory 11mm dovetail?

While the factory 11mm dovetail is functional, a one-piece Picatinny rail that screws directly to the receiver 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.

Which MOA base do I need for my CZ 457?

The choice depends on your shooting distance. A 0 MOA base is perfect for 0-200 yards. A 20 MOA base is the most popular choice for NRL22 and similar disciplines, allowing you to easily engage targets out to 300 yards. For extreme long range rimfire, our 30 MOA and 40 MOA bases provide the maximum possible elevation to push your .22LR to its absolute limit.

Will these mounts fit my CZ 455 or 452?

No. These mounts and bolt knobs are designed specifically for the CZ 457. The CZ 455 and 452 have different receiver contours and hole spacings. Please see our main CZ category page to find the correct parts for your rifle.
