So I am new to air guns but not new to shooting. I got very used to using a non-magnified red dot while in the Army. I would like to use at least a 4x powered red dot as I am very comfortable with them. What are the pros and cons of them on air guns and what is a good one to consider? I have a ruger impact max so seems mounting wont be a issue with the weaver rail on it. I will be using it for hunting and plinking.
