Foxtail Adapter Plate Fox 100010 Red Dot Adptr Glkmos 407K 507K

The Foxtail Precision adapter plate is a precision-machined solution for mounting red dot sights to Glock MOS-pattern slides. If you're running a Holosun 407K, 507K, or EPS Carry optic on a Glock platform, this aluminum adapter plate bridges the gap between your slide and your optic's footprint, ensuring a solid, repeatable mount. Built from black anodized aluminum, it's engineered to handle the recoil and daily carry use that Glock shooters demand.

Glock MOS slides opened up a whole category of carry guns that could take modern compact red dots, but not every optic footprint aligns perfectly with the factory pattern. That's where a quality adapter plate earns its place in your setup. The Foxtail 100010 is designed specifically to make popular Holosun models work seamlessly on MOS platforms, so you get the sight picture and reliability you chose without compromise.

Whether you're building a duty gun, a competition rig, or a carry piece, having the right adapter plate is the foundation. Black anodized finish resists corrosion and plays well with modern pistol aesthetics. This isn't a workaround—it's the right way to mount your optic to your slide.

Frequently Asked Questions

Will this adapter plate work with my Glock MOS and Holosun 507K?

Yes. The Foxtail 100010 is specifically engineered for Glock MOS slides and is compatible with the Holosun 407K, 507K, and EPS Carry pattern footprints.

What material is this adapter plate made from?

The adapter plate is machined from aluminum and finished with black anodizing for durability and corrosion resistance.

Is this the same as a mounting base or do I need both?

The adapter plate serves as the interface between your Glock MOS slide and your red dot sight. It replaces the need for a separate base by aligning your optic's footprint with the MOS pattern on your slide.
