Red Dots That Are Compatible With the Trijicon RMR Mounting Standard
Few sight configurations can compare to the accuracy and effectiveness guaranteed by fitting a Trijicon RMR optic on your pistol.
It comes with a rugged build, multi-coated lens, adjustable windage/ elevation, and is multi-platform ready for different primary applications.
There are benefits to other red dots that might draw you due to your own preferences and use, the price being one huge factor.
That’s why I’ve made a list of red dots compatible with the Trijicon RMR mounting standard so you can skip the hassle of scrolling through page after page to find your options.
Now, the top of the slide of a pistol only mounts the plates, and the plates are what mounts the optics.
That’s why you want red dots that will fit RMR cut aftermarket slides and adapter plates.
All these red dots are compatible with the RMR footprint and will secure the sight reliably.
So, with that said, here are the current RMR footprint optics that fit the Trijicon standard.
- ADE Advanced Optics RD3-020 Raptor
- ADE Advanced Optics RD3-019 Stingray
- Holosun 407C
- Holosun 507C
- Holosun 508T X2
- Riton X3 Tactix PRD
- Trijicon RMR
- Trijicon SRO
Trijicon RMR Footprint Dimensions
The Trijicon RMR footprint is the most popular and industry-standard footprint we currently have, and it’s an effective optic configuration for pistols.
Now, when we say footprint, we’re talking about the configuration of the mounting area. The dimensions of that mounting area, the screw positions – that’s the footprint.
It’s what affects the size and shape of the optic you can mount.
So it’s crucial to get it right…
This mounting standard has two sockets to pin on the front and two holes for screws in the middle of the sight.
Its compact nature is among the primary reasons for Trijicon’s RMR widespread popularity in the shooting community, with dimensions of 1.8 x 0.95 x 0.97 inches.

If what you’re after is the Trijicon Optics RMR, here’s more about it so you can make an informed decision and decide whether this may be better than the other options listed above.
You probably already know that the Trijicon Optics RMR is a famous red dot pistol sight that offers you more than what an average scope can.
