Night Fision Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate and Backup Sight Combo is machined from 17-4 stainless steel and finished with a nitride coating for long term durability against recoil and daily carry wear. At 0.2 inches thick the plate adapts the Glock full size MOS footprint to accept a Trijicon RMR Holosun 507C or any other optic sharing that compatible mounting pattern. This gives shooters flexibility to run their optic of choice without being locked into a single brand footprint. The plate is purpose built to fit Glock MOS models such as the 17 19 45 and 47 excluding Slimline variants. Paired with the plate is a tritium front sight finished in yellow for fast visual acquisition alongside a black rear sight both designed to co witness through the optic window. This setup ensures a usable iron sight backup remains available if the mounted optic fails or runs out of battery. Each package includes extra mounting screws and an installation tool simplifying setup without needing separate hardware. The Night Fision Optic Plate and Backup Sight Combo delivers a complete precision fit mounting and co witness sighting solution for Glock MOS pistol owners running a red dot optic.
