Night Fision Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate and Backup Sight Combo is built specifically for Glock MOS Slimline models giving the Glock 43X and 48 MOS a precise mounting surface for a Holosun 507K or another optic sharing that footprint. Machined from 17-4 stainless steel and built to tight tolerances the plate is engineered to withstand harsh recoil cycles without loosening or shifting zero over time. A nitride coating adds further corrosion resistance and wear protection extending the plate s service life under daily carry conditions. The package includes extra screws and an installation tool simplifying the mounting process for the end user. Because the included black sights are designed to co-witness with most optics sharing this mounting footprint the shooter retains a reliable backup sighting option if the red dot ever fails or runs out of battery. This co-witness capability is especially valuable for a concealed carry pistol where consistent sight availability matters in a self-defense scenario. Pairing the optic plate and sights in one package also simplifies the upgrade process letting the owner install both components together rather than sourcing them separately. The Night Fision Optic Plate and Backup Sight Combo for the Glock 43X/48 MOS is available for sale at GrabAGun for shooters adding red dot capability to their everyday carry pistol.
