Steel CZ 457 Picatinny rails

Steel CZ 457 Picatinny rails prioritize rigidity and thread strength for a rock-solid optic base on the 457—ideal when zero retention matters most.

• Why steel? highest stiffness and durable threads; adds a little weight for stability.
• MOA options: choose 0 MOA for general rimfire use or 20 MOA for extra elevation at distance.
• Fit: made for the CZ 457 receiver (11 mm dovetail clamp or screw-on, depending on maker).

Install tips

• Degrease rail, receiver and screws; apply Loctite threadlocker.
• Torque to spec in a criss-cross pattern; witness-mark and recheck after the first range session.
• Confirm screw length/pitch—no bolt or barrel interference.
