EGW
The EGW CZ 452, 453, 455, 457, 511, 512 11mm HD scope bases bring modern optics mounting to CZ's classic rimfire and centerfire rifles without drilling or tapping your receiver. Built from 7075 T6 extruded aluminum, these heavy-duty bases are precision-machined to accept both Picatinny and Weaver rings, giving you the flexibility to choose your preferred optic and adjust eye relief quickly and easily. The one-piece rail design keeps your scope closer to the barrel centerline, which translates to improved accuracy and a more compact sight picture—especially valuable on lighter-recoiling rifles where you want every advantage at distance or on the bench.
These mounts are purpose-built for shooters who want serious rigidity without unnecessary weight. The heavy-duty profile sits .100" lower than EGW's lightweight bases, offering a balance between durability and handling. The Picatinny slots are gauged to MIL-STD 1913 specifications (±.002"), so your rings will lock in precisely every time. Installation is straightforward—the bases are drilled to fit your factory scope mount holes, meaning you're mounting in minutes with the included Torx socket screws and wrench.
Whether you're setting up a 452 for small-game hunting, dialing in a 455 for precision rifle work, or running optics on a 511 or 512, these bases give you a modern, versatile platform that won't compromise the inherent accuracy of your CZ. The rigid aluminum construction and precision tolerancing mean your zero will stay put, round after round. EGW recommends 20 inch-pounds of torque and a drop of blue Loctite during installation.
