The biggest issue I have had with using a red dot, is that they don't gather any ambient light. I had a situation this year hunting deer where I could clearly see the buck I wanted to shoot with the naked eye and could have taken him easily with the cheapest rifle scope you could buy, however, I couldn't make him out at all with my ultradot 30! He was a nice one and was close enough to take with open sights. I've got a couple of 2x Leupolds I'd like to try now just to see if they will gather some amount of light.
