Night Fision Optic Adapter Plate Holosun 509T Footprint Black Nitride Stainless Steel - Fits Glock Full Size/Compact MOS

The Night Fision GLK-OP-509T-FSMOS is a precision optic adapter plate that lets a shooter mount a Holosun 509T red dot (or any optic sharing the same mounting footprint) directly to a Glock Modular Optics System (MOS) pistol slide. Precision-machined from 17-4 stainless steel and finished with a rugged black nitride coating, this plate offers serious wear and corrosion resistance for hard-use defensive, duty, and competition applications.

Built specifically for the Glock Full Size and Compact MOS line, the plate drops into the factory MOS cutout on the Glock 17 MOS, 19 MOS, and 47 MOS and provides a secure, precision-fit mounting surface that holds your zero round after round. It is not compatible with Slimline/43X/48 MOS slides. The 509T footprint pattern also accepts a range of other enclosed-emitter and open-reflex red dots built to the same mounting spec, giving you flexibility as your optic choice evolves.

Whether you are building a duty pistol, a defensive carry setup, or a competition rig, the Night Fision 509T optic plate delivers a precise fit and a tough finish that keep your mounted optic locked in shot after shot.
