extremely easy to instll.
I thought you can directly install the Trijicon RMR on to the rail but you still need the mount(RM 33 or 34 for Picatinny rail). Ignorance on my part but just in case any of you are considering similar setup.
It would be great if it came in a quick detach version.
I went with it because it's cheaper than the trijicon one and it works just as well
Pros: easy to install
