Does anyone have any experience with the C-more Scout on a fixed handle AR? I haven't been to the eye doctor, but it's apparent that my 36 year old eyes aren't seeing 20/10 anymore. Is the Scout a decent option for optics on my current upper, or am I better off buying a new upper first? I'll be using it for lunch hour 200 yard plinking at steel gongs, and occassional 3 gun matches.
