Cmore rts2r - C-MORE RTS2R Red Dot Sight

I like a larger sight window, but I do not like the tube effect with the aimpoints, and did not want the length associated with the CMore Rail (I own aim points, etch and CMore rails, all great optic as well), so I decided to try the RTS2R. It is very compact and has a large sight window for it's size. I have mounted this on a Marlin Guide Gun in .45-70 and it is working out great. I have given it 4 stars instead of 5 stars only because I have not wrung it out over many range trips yet, so I am cannot verify it's durability yet. If it is anything like the rest of the CMore product line, it should be good to go.
