CZ 455 Picatinny rails convert the 11 mm receiver dovetail into a universal Picatinny base for modern rings, one-piece mounts, and red dots with Picatinny adapters.
Why add a rail?
Universal interface: easy fit for scopes, micro dots (with bases), and night/thermal devices.
Repeatable zero: cross-slots resist shift and make optic swaps straightforward.
Fit & material
Model-specific: select a rail made for the CZ 455 11 mm dovetail (clamp-on or screw-on, per the maker).
Aluminum vs. steel: aluminum saves weight; steel maximizes rigidity and thread strength.
