I have two. One is the 4-16x56 buck gold the other is a 6-25x56. I love mine. Both shoot great in low light conditions, both hold zero well, and both track well. I don't know how much adjustment is in the scope, but I have plenty for the 300 meter shooting that I do where I live. I don't have a further range to go out on. If I need more adjustment, Ill just get a 20 moa base.
