My experience with red dots is to get one that uses either red or green because you can't see sh*t in bright sunlight using the red dot. Use the green during bright sunlight and red in dimmer light. Other than that, after having two different ones from big name manufacturers, I say get a riflescope and bypass the "dot" scopes altogether. They (most) don't have to depend on batteries and it's easy to forget and leave this thing on. If you are shooting close, get a compact 4x scope, that's my suggestion.
