out of curiosity what is your price range? that makes a huge difference with the range of optics available.
as you already know, i can't help you much. do you have a big sporting goods store (cabelas, bass pro) where you can get the opportunity to look through several different models?
i always try to narrow it down to a half dozen scopes/red dots through research and reviews, then i do my best to get my mitts on as many as i can. you can never really
know till you look through them & handle them yourself.
sorry, best advice i can offer with my limited experience with red dots/reflex sights. it is a mess out there with so many models/brands to chose from. its really overload sometimes.
