Night Fision GLK-OPBS-509T-MOS Optic Adapter Plate with Backup Sight Combo Black Nitride 17-4 Stainless Steel - Fits Full Size Glock MOS

The Night Fision Optic Adapter Plate with Backup Sight Combo drops onto Full Size Glock MOS pistols to give you a precision mounting surface for red dot optics using the Holosun 509T footprint. CNC-machined from premium 17-4 stainless steel and finished in corrosion-resistant black nitride, the plate holds up to hard use and harsh recoil without warping or shifting zero.

Built specifically for Glock 17 MOS, Glock 19 MOS, and Glock 47 MOS pistols equipped with the factory Modular Optic System cut, the plate is machined to Night Fision's tight tolerances for a secure, repeatable fit. The low-glare black nitride surface blends cleanly with factory and aftermarket slide finishes, and the included black backup sights give you a dependable aiming option whenever the primary optic is removed or goes down.

Whether you are setting up a duty pistol, building a competition rig, or just want a clean factory-style optic mount, this plate and sight combo delivers a ready-to-install foundation for any 509T-footprint red dot straight out of the box.
