Night Force windage knob problem. Advise please.
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 back,at zero,and at 2 MOA where it used to be,but every thing was useless,so I tighten it,but it looks like it has 40 MOA of correction,and I am afraid that the gap may get dust into the scope.I can live with it,but I am really disapointe with my *mechanical hability*.
By the way I tried to take out the battery,but it is very tight and I´m afraid to use any tool. I cant send it to service,and now it is ilegal in my country to mail it abroad. Any thougts. Advise please.
Thank you for reading.
