🧠 FAQs – RMR Footprint Optics
Q: What red dot sights use the RMR footprint?
A: Optics like the Trijicon RMR, SRO, Holosun 507C, 508T, and Viridian RFX35 all use the standard RMR mounting pattern.
Q: Can I use these optics on my Glock MOS?
A: Yes — with the correct adapter plate or slide cut, RMR footprint red dots will mount directly to Glock MOS slides.
Q: What’s the difference between RMR and RMSc footprints?
A: RMR is a larger footprint used for full-size optics, while RMSc is smaller and fits micro red dots for subcompacts like the Glock 43x/48.
Q: What’s the best green dot RMR optic?
A: The Holosun 507C-GR and Viridian RFX35 are top-rated for daylight visibility and motion-activated auto-on functionality.
Q: Can I co-witness these optics with iron sights?
A: Yes. With suppressor-height sights, you can achieve lower 1/3 or absolute co-witness depending on your setup.
