All, I am just getting into the AR world and have purchased my first AR, a Sig M400 Enhanced. I am looking for optics for it but don't want to spend a bunch of money until I know what I like on it. Right now, I would like to try a red dot scope that will give me accuracy out to around 100 yards, at least. I want to spend $200 or less. Once I determine if I like that, I may move it to my Mini 14 and then go the EOTECH, AIMPOINT route. Can any of you give me some suggestions from personal experience as to what brand of red dot to try? Thanks for all your help. I appreciate the availability of all you knowledgeable people.
