Night Fision Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate + Backup Sight Combo is machined from premium 17-4 stainless steel which means it is built to the tight tolerances needed to withstand harsh recoil while ensuring a secure accurate fit on the slide. A nitride coating is applied over the plate for extra protection adding wear and corrosion resistance beyond what bare stainless steel offers on its own. The plate is specifically designed for the Aimpoint ACRO footprint so it mounts a compatible red dot directly to the slide without requiring an adapter. Because the sights are designed to co-witness with most optics that share this footprint shooters retain a fast backup aiming reference even if the red dot fails or runs out of battery. This combo pairs the optic plate with a tritium front night sight finished in yellow alongside a black rear sight giving shooters a visible aiming reference in both bright daylight and low light conditions. It is built to fit full size Glock MOS models including the 19 17 45 and 47 though it excludes Slimline variants due to differing slide dimensions. Each package includes extra mounting screws along with an installation tool so users have everything needed to complete the swap without sourcing separate hardware. For Glock MOS owners who want a durable co-witnessing sight and optic plate combination Night Fision delivers precision and reliability in one package.
