I was recently looking a red dot for my AR. I did tons of research online and watching videos. I had a budget so some of the higher end models were out of the question. If you're looking a good red dot for less than $200...I think this is a good choice. This video was a darn good review and torture test of it: And this kinda put the nail in the coffin and made my decision more confirmed.
