View Full Version : Where Do You Mount Your RMR On A Carbine?

Started running a Trijicon RMR on a carbine with 1/3 lower cowit located far forward on the receiver. Only because I've always run AP RDS that way. Then just now placed it far back.

Feels a bit faster as the window is closer/larger that way but have not run any live fire comparisons. Anyone else experiment with this?

First you have to find someone using a RMR on an M4. There are probably only a handful doing it. Half of those are sponsored shooters. Do what works best for your application.

If I had to mount one, it would be on a 45 degree mount combined with a fixed power scope. As a primary optic? No thanks.

I wouldn't run anything with an exposed projector as the main optic.

Your experiences with the RMR are different than my own.

During Tropical Storm Cindy, despite torrents of rain, I had no issues with either the RM07 or RM09. If anything, I had a harder time seeing the target itself than the dot.

Thanks that's valuable information
What waterproofing did you do to your RMRs?
I just have the sealing plate

I’ve only shot the RMR in heavy rain once, and it wasn’t as bad as the Internet led me to believe, but it still wasn’t great.

No secret sauce here. The only thing I can chalk it up to is going with the larger-diameter reticles (6.5/9.0 MOA).

Running optics in the rain sucks, period.

That’s probably true, I wouldn’t be surprised if that weather caused just about every other optic to at least fog up.
