As said, they are low-end scopes, but having said that, the Monarchs I've got, which are 3-12, do not have tunneling. Nikon is supposed to have good warranty service. Call them... On second thought, I suppose you have adjusted your eye relief to try to get rid of the tunneling?

+1 Tunneling on all powers would probably be the eye relief isn't set right. Move the scope back or forward and see if it disappears. If not then call Nikon.
Thanks guys, I have it on a CVA Pro and I am out of room to come back any further. I had it on a Savage .17 at 1 time and had the same trouble no matter how close I got to it. Other than that the scope is very good. I guess it time to call them. Thanks again Brian
