Rick emails to point out this guy who has collected an astonishing number of manuals. Hundreds of them. He generously is hosting these PDFs for our benefit, but asks that if you have one that he doesn't, to please send it to him.
Firearms manuals and stuff (like Maglite and Surefire)
Reloading stuff (scroll down)
The series of tubes, helping your shoulder thing go up. Well done.
