Here is what I have: I have box and all manuals, paperwork that came with it. It was fired for... 20 rounds. What I'm looking for is one that's a little lower profile. Basically dot being lower towards center of barrel. Something similar to: Notice that it's allen screws on the side. I can't deal with huge knobs. I would really prefer one with a circle pattern, as this is all for quick acqusition of a target.
