Bill,

Thanks for the pointer. I found several references to these threads
and tracked several of them down. I had in fact found this list by
searching for other information on the Mark 15 on Google and so had
already read several of these threads. Very informative.

Looking them over again, I find reference to loose adjustment screws
but no reference to how to tighten them up a bit.

Maybe a general search on making screws tighter in a metal working
context would provide some good information.

Thanks for the input.
