An awesome buddy of mind came across the website of Stephen Ricciardelli. Stephen has gone to the trouble of putting up almost every manual that I could ever want for any of my guns, rifles, shotguns, etc… as PDF’s. Stephen makes it a point to mention that you shouldn’t download all of the manuals to conserve his bandwidth, which is expensive. I think this collection is an invaluable resource and should be used as needed. I downloaded a Heckler and Koch G3 Armorers Manual for my PTR-91. I uploaded the PDF to my site just in case anyone wants to grab a copy.
