Does the Steiner MPS fit the CZ Shadow 2 Optics Ready?
Page last updated . Data compiled September 2026 by the site administrator.
Yes, with an adapter plate: the Shadow 2 OR → ACRO / MPS, a CZ factory part.
Adapter plate required
Enclosed emitterThe slide isn't cut for this pattern. One plate adapts it, listed below. The plate gives the optic's clamp a rail to grip.

Same answer forThe Steiner MPS goes on the CZ Shadow 2 Compact Optics Ready the same way: it shares this slide's optic cut.

New to red dots? What footprint, plate, co-witness and the rest mean
Will your iron sights co-witness?With standard-height irons: No co-witness. Standard-height irons sit well below any pistol red dot window and are only usable with the optic off. Suppressor-height sights fix that; a different optic won't. Little or no data: no sight maker publishes co-witness heights for standard-height irons with this pair, so "no co-witness" is the typical case, not a rule. Some optics still show factory-height irons in the lower third or lower fifth of the window, so check your own front sight against the window before you rely on it.With suppressor-height irons: Low at best. An enclosed emitter on a plate sits tall, so suppressor-height irons land at the very bottom of the window or below it: Night Fision lists its .290 in front sight as a lower 1/5 co-witness for an ACRO P-2 on GLOCK's MOS plate, and taller optics lose them. Sights taller than suppressor height are the usual fix. Estimated: no sight maker publishes heights for this pair, so that's the typical case for this kind of optic, not a guarantee: pistols don't standardize sight and optic heights the way rifles do.
How this slide mounts an opticCompetition-oriented plate set; steel plates are common because of the round counts these guns see.

What to order, and how to fit it
The fit checker's build sheet for this pair, assuming sights of unknown height. Open it in the fit checker to set your sights, work out screw length from your own caliper readings, or copy it as text.
Rather not do it yourself? Mounting an optic is a short bench job for most gun shops and gunsmiths. Buy the parts under "Parts to order" and print this page for the shop: it lists what is not on file for this pair, so they know which figures to take from the makers, and ends with a blank log for whoever does the work. How an install goes, from the makers' manuals.

Fasteners: which bag
You don't buy these. Screws come with the pistol, the optic and the plate, and they look alike. The thread is tapped into the slide or plate (the optic only has a clearance hole), so they decide the thread, not the optic.
| Joint | Thread | Comes from |
|---|---|---|
| Plate → slide | set by the slide | Supplied with the plate. The one screwed joint in this stack, so it gets the threadlocker and the torque check. Keep the pistol's cover-plate screws apart from these. |
| Optic → interface | Cross-bolt clamp | Supplied with the optic. The ACRO clamps rather than bolting through, so there's no screw length to get wrong. Torque the cross-bolt to Aimpoint's figure. |
On the bench before you start
- Torque wrench — set to the figure in your optic's manual
- Driver bits — T10 / hex per model, fully seated so they don't round the head
- Calipers — for the screw length check below
- Blue removable threadlocker — Vibra-Tite VC-3 or Loctite 242. Never red.
- Degreaser — isopropyl or brake cleaner
- A parts tray — you'll have three bags of look-alike screws
- Witness-mark paint or lacquer — so you can see if anything moves later

Not on file for this build
Where a figure is not published, this sheet says so instead of guessing. Get these from the maker or your gunsmith.
- Screw length
- Never published here, because it depends on your exact stack. Measure it and test-fit dry.
Sequence
- Clear the pistol. Drop the magazine, lock the slide back, look and feel the chamber, then do it again.
- Remove the factory cover plate and set its screws aside. They are not optic screws.
- Degrease the slide pocket, both faces of the plate and the optic base. Oil under a plate lets it move.
- Seat the plate on the slide, check it sits flat with no rock, and fit its screws with blue threadlocker.
- Torque the plate to spec, bringing the screws up evenly rather than one at a time.
- Set the optic on the plate's rail and tighten its cross-bolt clamp to Aimpoint's figure. There are no optic screws to fit.
- Let the threadlocker cure before firing (check the bottle; usually a few hours to overnight).
- Confirm zero at your working distance, then re-check torque after the first 100–200 rounds.
Before you fire it
- Screw length checked dry: it must not bottom out on the slide or reach the striker channel.
- Optic sits flat with no rock, and the screws pulled up evenly.
- Torque set with a wrench, not by feel. Witness-mark the screws so movement is visible later.
- Threadlocker cured.
- Function check, then zero confirmed live.
Screw length is the one that hurts
Too long and a screw bottoms out on the slide or reaches the striker channel; too short and it strips under recoil. This sheet gives the thread but can't give the length, which depends on your exact plate and optic stack. Test-fit dry and count threads.

Sight co-witness
Answered above: co-witness with standard and suppressor-height irons.
Confirm the firearm is unloaded before any work on the slide. Mounting an optic is gunsmithing: stay within your competence and use a gunsmith when a job is past it. Provided as-is with no warranty; you use this at your own risk. Prices are approximate street-price bands from September 2026. Torque and fitment figures come from manufacturer documentation; confirm against the current manuals for your pistol, optic and plate before installing.
