Hello, I'm new to this forum and was wondering if someone could help me out. I purchased a reproduction M84 from James River Armory to put on my 1903Afaux. I like the original M84 I have on my M1D so I proceded to zero it out my repro just like my original. However it didn't work. Every time I loosen the outer screw the inner screw turns and when I adjust the range know and tight it back up I'm not where I wanted to be. Am I doing somthing wrong or is this a problem with the reproductions. If so is there anyway around this?

I called James River and the owner was not able to help me and I was rather annoyed that he was selling somthing that he knew nothing about. He said he gets them from Gibbs so Im awaiting to here back from them.
