HK VP9 OR Mounting Plate for Holosun 407K/507K/EPS - Black

The HK Mounting Plate is a factory optic adapter plate from Heckler & Koch (MPN 51000381), designed to mount Holosun "K" series red dot optics - including the 407K, 507K, and EPS - directly onto the slide of an HK VP9 OR (Optic Ready) pistol.

Cut to interface with the VP9 OR's factory-milled optic-cut slide, this 6.30" long, black plate provides the correct footprint and screw pattern so a Holosun K-series optic seats securely with proper sight alignment and a clean co-witness with the pistol's factory iron sights.

This dedicated HK adapter lets you run a modern micro red dot on your VP9 OR without resorting to universal-fit plates or aftermarket slide milling. New condition, ready to install with your Holosun K-series optic.
