Adapter Plate for Glock MOS, Holosun 407K | 507K | EPS Carry | EPS

Adapter Plate for Glock MOS, Holosun 407K | 507K | EPS Carry | EPS

This CNC-machined adapter plate by Holosun allows micro red dots with the Holosun K footprint to be mounted directly on the factory Glock MOS interface. The plate replaces the original MOS mounting plates and creates a low, stable connection between slide and sight – without additional intermediate adapters.

The plate is made of high-strength 7075 aluminum with a black hard-anodized surface. The one-piece design with raised rear locating pins ensures a reliable fit of the sight and consistent point of impact (zero hold). Mounting screws in two lengths and a matching wrench are included.

Key features:

• Sturdy aluminum construction: CNC-machined from high-strength 7075 aluminum, black hard-anodized for a scratch- and corrosion-resistant surface.
• One-piece design: Low profile and reliable fit of the sight (zero hold), raised rear locating pins for additional stability.
• Easy installation: Screws in two lengths and wrench included, no gunsmith required.
