So, I bought a fairly cheap RDS for my 15-22 and I have been having some trouble sighting it in. Effectively, it seems that the adjustment knobs don't seem to do anything at all (tried it with the irons on, in grip, with my eye in one place, and the dot wouldn't move relative to the front sight at all).
Any suggestions? I am getting the feeling that this RDS might be a dud..
