This sight in a word SUCKS... Jerkface11 bought one and like him I tought a 2 power red dot would be cool, NOT! Looking through the sight you have a terrible "fish eye" effect on top of the fact that 2x isn'e enough magnifacation to notice. That is if you can keep from getting sick from looking through the sight too long.
You'll be a lot happier with a conventonal 30mm red dot
