Good scope for the price. The reviewer above (johnegadget) obviously does not know how to read. If he would have looked at the instruction manual the he would have known how to adjust the sights. They have dials at the bottom that lock them in place so they don't get changed accidently. There are better scopes out there but your going to pay for it. It is hard to see the ilimination in the day time but I don't use it anyway the black reticule is fine for me.
