The Night Fision GLK-OPBS-RMR-MOS-YGZX is a direct-fit optic mounting plate and backup night sight combo, purpose-built for the Glock Full Size MOS platform, including the Glock 17, 19, and 47. The plate is cut to the popular Trijicon RMR / Holosun 507C footprint, allowing the shooter to mount a compact red dot on the factory MOS slide while still carrying co-witness-capable iron sights as backup.
Both the plate and the included night sights are precision-machined from 17-4 stainless steel and finished in a low-glare black nitride coating for excellent wear and corrosion resistance. The yellow tritium front sight is paired with a blacked-out rear, giving the shooter a fast, high-contrast aiming point in low light while the rear stays snag-free and visually unobtrusive.
Designed as a direct replacement for the factory MOS cover plate, this combo provides a secure, repeatable mounting platform for a Trijicon RMR, Holosun 507C, or any other red dot sharing the RMR footprint. The included night sights give the shooter an aiming fallback should the optic ever fail, making this a complete red-dot-ready solution for the Glock MOS pistol.
This is a brand-new, current-production accessory combo from Night Fision.
