Night Fision Optic Adapter Plate 507K/407K for Glock 43X/48 MOS - 17-4 Stainless Steel Black Nitride

The Night Fision Optic Adapter Plate is a precision-machined mounting solution that lets you mount a Holosun 407K or 507K footprint red dot directly to the slide of a Glock 43X MOS or Glock 48 MOS pistol. The plate drops onto the factory Slimline MOS cut, giving you a secure, repeatable interface for your K-footprint optic with no custom machining required.

Each plate is precision-machined from 17-4 stainless steel for excellent strength and dimensional stability, then finished with a wear and corrosion-resistant black nitride coating. At roughly 0.2" thick, the plate keeps a low profile while providing a rigid mounting surface for the optic. Mounting hardware is included for a complete, ready-to-install setup.

In addition to the Holosun 407K and 507K, the plate is compatible with any red dot optic that shares the standard K-series mounting footprint. Whether you're running a compact reflex sight for defensive carry or range use, this Night Fision adapter plate offers a reliable, no-gunsmith mounting solution for your Glock Slimline MOS platform.
