If you don't mind the size. I have good luck with the Tasco and BSA red dot. I think they are 30mm. I have a couple of them on .22's and have never had any problem. Except maybe killing a battery. I am not too crazy about the multi color ones you cant turn the brightness down enough. I also have one of the small Dr. Optics or something like that it is hard to adjust and mine wont stay put It cost around 200 bucks I'm sure they are better now mine is several years old. I like the 30 dollar one better. Not sure if you can still buy it for that at wally world or not. Been a few years since I bought mine. Besides its wally world,if you don't like it take it back.
