🔧 Mounting Compatibility Tips

• Glock MOS & P320 RX: Most models need an adapter plate for RMR footprint red dots unless you have a direct-cut slide.
• AR-15 Platforms: Use an RMR riser mount for co-witness or low-mount positioning on flat-top receivers.
• Compact Pistols: The RMR footprint is larger than RMSc — check slide cuts before ordering for micro carry guns.

❓ Frequently Asked Questions (FAQ)

What is an RMR footprint?

The RMR footprint is a mounting pattern developed by Trijicon. It uses two screws and two recoil lugs and has become a standard for reflex sights due to its strength and compatibility.

Can I mount an RMR footprint red dot to a Glock MOS?

Yes, most Glock MOS slides are compatible with RMR optics using an adapter plate — or directly if the slide is cut to match.

What’s the difference between RMR and RMSc?

RMR footprints are larger and used on full-size optics. RMSc is a micro footprint found on small, slim pistols like the Glock 43X or Springfield Hellcat.

Do I need a riser mount for AR-15 use?

Yes — an RMR riser mount is recommended to align the red dot with your iron sights or achieve proper eye-level height on AR platforms.
