I bought a Copper John Deadnuts to put on my new Mighty Mite. I was loving the sight, until today. The screw that adjust the windage on the sight has already gotten rounded on the inside (it's a hex). I emailed Copper John Corp. to see if they'll send me another screw b/c this sight is useless if I can't adjust it. Anyone else ever have this happen? I believe I was using the proper size to adjust the screw, but I slipped a couple times trying to loosen it, as this thing tends to need to be pretty tight to hold the sight window in place.

Now I need to figure out how to remove the screw if they do send me another.
