Patrick,
That is the exact same one I gave gunner when this thread was first started. Actually I gave him the entire document for every last part to the gun. I believe it was around 50 pages, but I could be mistaken. It makes me wonder if me and weaponengineer got it from the same place, another forum that specializes in building weapons. Kind of funny anyhow. PM me your email address if you want the set too and I'll send it to you.
