🔧 What Is an RMR Conversion Plate?

An RMR conversion plate is a mounting adapter that allows you to install non-RMR optics (like Holosun 507K, EPS, DeltaPoint Pro, etc.) onto a slide, mount, or base that's already cut for the Trijicon RMR footprint.

This means you can switch optics without changing your slide — saving time, money, and gunsmithing costs.

❓ Frequently Asked Questions (FAQ)

What is the RMR footprint?

The RMR footprint refers to the bolt pattern used by the Trijicon RMR red dot sight. It's one of the most widely used footprints on modern pistols and mounts.

Which optics can I use with an RMR conversion plate?

Depending on the plate, you can adapt the RMR footprint to fit red dots like Holosun 407K / 507K / EPS, Leupold DeltaPoint Pro, Shield RMS, and others.

Is gunsmithing required to use a conversion plate?

No. These are drop-in adapter plates — simply mount them to your slide or base using the included hardware.

Are screws and mounting hardware included?

Yes. Every adapter plate listed includes the necessary screws and, in most cases, alignment posts or T-nuts for secure mounting.

Can I co-witness with iron sights after installing an adapter plate?

It depends on the optic and sight height, but many of these plates are low-profile enough to allow co-witness with standard suppressor-height sights.
