Hi. I'm stupid so bear with me. I have a Glock 17 slide with the rmr cut and I need an adapter plate so I can mount a mos optic to the gun. I'm going to give Gidion Optics granite red dot a shot and the red dot is set up for mos. All I'm finding is mos to rmr

Just stop.

Buy a Holosun 407C (or any RMR footprint optic) and mount it directly to your slide.

No one makes an RMR to MOS adapter plate...why would anyone want to convert the most ubiquitous optic footprint (RMR) to a proprietary Glock footprint, that was designed to use adapter plates?

You know they make the Granite in RMR footprint as well.

Granite Comp, but not carry. Although maybe he already has the MOS version?
