Helpful Positive Review Can't be beat with the RMR by Darren Hill, Verified Owner, July 21, 2017
This setup will turn any head. I took for granted having an ACOG when I was in the service and I'm glad to have one of these and it's especially nice with the RMR. Went with the red reticle and it's easy to see in full sunlight and low light conditi...
