I recently picked up the SW22 and want to run an optic on it. To start my budget needs to stay at or below $100. I'm open to either style of red dot but my son who is part owner prefers the reflex style. I would love to hear any and all opinions on what style and brand of optic you are running. It also doesn't have to be on the SW22. If you are running one on the Ruger MK series that's fine too. The more the merrier. TIA for your help.
