Why Choose This Product

Factory dovetail mounts can limit optic options and introduce potential flex under recoil or during transport. This EGW HD rail solves those issues with a solid, one-piece aluminum construction that maintains zero shot after shot. The 20 MOA cant is ideal for NRL22, PRS rimfire, or any scenario requiring maximum elevation adjustment on .22LR platforms. Whether you’re building a dedicated long-range rimfire rig or upgrading an existing CZ 457, this mount offers repeatable performance and broad compatibility with Picatinny and Weaver rings.

Installation is straightforward: apply blue Loctite to the included screws, torque to spec, and attach your optic. The result is a rock-solid foundation that enhances accuracy and confidence on the range.

Installation Notes

Confirm your CZ 457 receiver matches the factory tapped pattern. Use the provided hardware and torque values for secure mounting without damaging components. This base is not compatible with CZ 452, 453, 455, or other non-457 models due to receiver differences.

Upgrade your CZ 457 with the Evolution Gun Works HD 20 MOA Picatinny rail and experience the difference a purpose-built scope base makes in your shooting performance.
