The MPS fits any optic-ready pistol that accepts an ACRO-footprint mounting plate. It does not fit RMR-cut slides directly; you need an ACRO-compatible adapter plate from manufacturers such as APEX Tactical, Dawson Precision, Reptilia, or Unity Tactical. Check your pistol's slide cut and confirm the plate manufacturer offers an ACRO pattern before purchasing.

The MPS battery lasts approximately 13,000 hours at medium brightness. Yes, you can replace the CR1632 battery without removing the sight from your pistol. The top-mounted battery compartment cover unscrews with the included T-handle tool, letting you swap the cell and keep your zero intact every time.

The ACRO and RMR are two distinct mounting standards with different hole-pattern dimensions and profiles. An RMR-footprint sight seats directly into an RMR-cut slide, while an ACRO-footprint sight like the MPS requires an ACRO-cut slide or an RMR-to-ACRO adapter plate. Using the wrong footprint without a correct adapter will result in an improperly seated optic, zero shift under recoil, and potential equipment damage. Always confirm your slide cut before selecting a mounting plate.

Yes, the MPS includes two dedicated night-vision-compatible brightness modes alongside six standard day/night settings, for a total of eight brightness levels. Use the + or - button on the right side of the housing to cycle through them. To lock the current setting and prevent accidental changes, press both buttons at the same time.

Zero the MPS using the included hex wrench on the labeled adjustment turrets. The elevation turret is on top of the housing and the windage turret is on the right side, with directional rotation markings on each. One click equals 1 MOA, which moves your point of impact approximately 1 inch at 100 yards. The parallax is fixed at 25 meters and the sight is parallax-free from 10 to 150 meters, which covers all practical pistol engagement distances.
