I bought a Tasco ProPoint that I was planning on mounting to my 10/22, but I decided to try it out on my AR since I had it with me when I made my purchase. Also, I found a QD knock off that came in a plain white box with no label or markings of any kind. The mount came with a couple of different height risers and one gave me good cowitness. So far, it works pretty well. The QD grabs tight and seems to hold a zero. The Tasco is plenty bright and although the dot is 5moa, I had no problem getting really tight groups at distance. I still plan on getting either an Aimpoint + magnifier or an ACOG eventually, but for now, this little set up was well under 200 bucks and is working pretty well. I found that I like the sight mounted all the way to the rear for now. Next time at the range I will try it forward, back just feels more like a traditional rifle scope.
