So, I am considering a rmr for my Q5, I know the base plates are for doctor, Leopold and trijicon, what other rmr's, if any, will fit these plates?
Thank you, that's the info I was looking for.Vortex, Burris, and Doctor all use the same plate. Trijicon is Trijicon. Leupold uses the other plate included with the Q5. An FTP Alpha 3 and the Sig MAX both use the C-more plate which is the RTS-2 plate that you can get from Alpha Dynamics. The issue with the FTP Alpha 3 and the Sig Max is that you'll need to mill a tiny bit off the slide to accommodate for their longer length, or use a shim of some kind to build up the RTS 2 plate so it will clear the front of the slide. I had my slide milled.
