Steel CZ 457 Picatinny rails

(9 products)

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.
