This site is dedicated to archiving and making available the scattered material around the Internet on Heckler and Koch firearms, and bringing it together in one place as a community resource. There are currently 506 PDF files in the library, listed below. You can also view the image gallery, and the MG-42.Net Mirror.
There is also a audio/video presentation on various HK firearms available in the HK Multimedia tour. The materials from that presentation have been made available for view in the links of the gun names. I hope to add in more quality images as I can find them.
