Mossberg Model 46M, S102 elevation screw needed.
Yes, I have a screw loose, actually missing. I have corresponded with Vic at Havlin and they have someone who can make one (thanks Vic) but I was hoping someone had a spare original lying about. (I could also use a pound of $20s.)
If no one has one I will follow Vic's suggestion.
Have I mentioned how much I like this site?
