A while back, I had trouble with one of March High Master 48’s. The reticle suddenly moved and was clocked about 20 degrees in the scope.
A fiend gave me this number. I called, got instructions where to ship it. The scope was gone for about two weeks. When it returned, it contained a very cordial letter from a Japanese man, opolgizing for the inconvenience.
I’m not sure if that number is still good, but worth a try.
