Description
Night Fision’s Optic Plate and Backup Sight Combo is built for Glock full-size MOS pistols — specifically the shooter who wants to mount an Aimpoint ACRO without losing a functional set of irons in the process. The problem with most red dot conversions on MOS-cut slides is that the optic footprint swallows the rear sight channel entirely, leaving you with a front sight and nothing behind it. This combo addresses that directly by integrating blacked-out backup sights into the plate itself, so your irons remain co-witnessed and usable even when the optic is in place.
The plate is cut to the ACRO footprint and drops into the MOS adapter system the way the factory plates do, using the existing mounting hardware arrangement in the slide. Blacked-out sights are a deliberate choice for a backup role — tritium or fiber on a rear sight behind an optic creates visual clutter in the sight picture, while a clean black notch stays out of the way until you actually need it. If the optic fails or you transition to irons intentionally, the reference points are there.
This is a practical solution for carry or duty use where you want optics-primary capability without accepting a degraded fallback. It avoids the common workaround of suppressor-height sights that co-witness at an awkward height, since the sights are designed around the plate geometry from the start. Night Fision manufactures this as a matched set rather than two separate components adapted together, which matters for alignment consistency between the optic mount and the sight plane.
