Night Fision Precision Optic Mounting Plate: 507k/407k to Glock 43x/48 MOS

The Night Fision Precision Optic Mounting Plate bridges one of the most popular modern carry guns with compact red dot optics. If you run a Glock 43X or 48 MOS and want to mount a Holosun 507K, 407K, or other optic with that footprint, this plate gives you the precision fit and durability that separates a solid carry gun from a truly capable one. Night Fision built this plate from 17-4 stainless steel—the same material used in aerospace and high-stress applications—and applied a nitride coating for corrosion resistance and longevity in the field.

Machined to tight tolerances and 0.2 inches thick, the plate handles the recoil impulses of 9mm carry loads without flex or drift. Installation is straightforward: the package includes extra screws and a dedicated installation tool, so you're not hunting for the right hardware or jerry-rigging a mount on your nightstand. This is the kind of detail that makes the difference between a setup that holds zero and one that frustrates you at 3 a.m.

Glock MOS (Modular Optic System) slides have become the standard for compact defensive pistols, and red dots on carry guns are no longer exotic—they're practical. A quality mounting plate is the foundation of that setup, and this plate delivers without compromise.

Frequently Asked Questions

Will this plate work with my Holosun 507K on a Glock 43X MOS?

Yes. The Night Fision plate is designed specifically to mount 507K and 407K optics to Glock 43X and 48 MOS slides. As long as your red dot uses the 507K/407K footprint, you're good to go.

What's included, and do I need any additional tools?

The package includes the mounting plate, an installation tool, and extra screws. You don't need to source additional hardware.

Why does the plate thickness matter?

A 0.2-inch plate thickness provides rigid support and resists flexing under recoil, ensuring your optic holds zero reliably. Thinner plates can deflect and cause point-of-aim shifts over time.

How durable is the nitride coating?

Nitride coating is hard and corrosion-resistant, protecting the stainless steel underneath from wear and environmental exposure. It's the same finish used on precision firearms components.
