Well, I have a 4.5-22 X56 NXS,Zero stop scope. After I zeroed it at 100 meters,the windage knob was at 2 MOA to the right,I decided to put it to zero,I loosened the screw,and took the knob out OF THE SCOPE,when I put it back,it did not entered completly.It was 2 lines out,I tried hard to push it...
