The Trijicon RMR footprint is the most widely adopted mounting standard for pistol red dot sights — used across countless optics-ready slides, adapter plates and airsoft replicas. If your slide cut or optic plate is RMR-pattern, these sights drop straight on. At Xtreme Tactical we stock RMR-footprint red dots from Holosun and Trijicon, dispatched tracked from the UK.
This collection covers full-size optics including the Holosun 507C/407C series, the competition 507COMP, and the Trijicon SRO. Running a slim slide instead? See our RMSc footprint red dot sights. Browse all pistol dot sights, sealed enclosed red dot sights, or shop by brand in Holosun and Trijicon. Need to put one on a rifle or a shotgun? See red dot sight mounts, offset red dot sights and shotgun red dot sights.
Frequently Asked Questions
What is the RMR footprint?
It's the mounting pattern of the Trijicon RMR — two screws and a recoil-lug profile that has become an industry standard. Many pistols are cut for it directly, and most adapter-plate systems offer an RMR plate.
Will an RMR-footprint optic fit my host?
If the slide is milled for the RMR, or your optics-ready pistol includes an RMR plate, yes. Footprint compatibility is exact, so confirm the cut before ordering — our footprint compatibility chart lists what fits what, and mounting plates bridge the gap where it does not.
RMR or RMSc — which do I need?
RMR suits full-size pistols and competition guns; the smaller RMSc footprint suits slim and micro-compact slides. Check the cut to be sure, or read the RMR vs RMSc guide.
Does an RMR-footprint dot suit a rifle?
Yes — on a Picatinny mount an RMR-pattern optic makes a compact primary for a straight-pull or PCC, and an excellent 45-degree offset sight next to a magnified optic.
