I like to compare various red dot sights and all of my rifles except for my ancient 182-series Mini 14 are equipped with a Red Dot Sight. Lately I have been playing with the Aimpoint CompC3 on my Mini 15 Ranch Rifle. This has worked out superlatively well using the GG&G rail system on the Ranch Rifle. Holds zero great and no loosening of any of the screws even not using Loc Tight.
Here is the rig:
The CompC3 is a very good optic for the Ranch Rifle. Just as high quality as an H-1 (although larger) it is great for applications where size is not critical, as on a Mini. I've put about 200 rounds through the rifle with it and the results have been extremely satisfactory; limited only by my own limited skills.
Anyway, if you are trying to decide what kind of non-magnified optic to go with on your Ranch Rifle, this setup has worked well for me.
