I just bought my new Nightforce 5.5x22x56 NXS yesterday (Tuesday) and already have a problem. My focus on the scope was a little fuzzy so I opened the owners manual and was reading how to adjust the focus. It said to rotate the eye piece away from the locking ring. I tried to do that with no success. The two were one and the same as far as I could tell. Then I noticed a little screw on the magnification ring/dial. I then loosened that screw, barely backing it out. Well the screw came right out with my Allen Wrench. I still could not adjust the focus. That screw which stops the magnification ring at 5.5 and then 22 when turned the other direction will NOT go back in. I then kept rotating the magnification ring both ways, several complete rotations looking through the screw hole looking for a "screw receiver" inside the scope that the screw would screw into. There isn't one. Upon inspecting the screw hole, it looks like the threads are stripped out. I can "tighten" the screw all I want but it does not "bite". It just spins continuously. I haven't even had this scope 24 hours and I have already managed to mess it up. I am guessing that I am going to have to send it to the factory for repair.
