I came across this looking for CAD drawings of the SKS FSB...
https://grabcad.com/library/sks-59-66a1
It features several images of a Yugo that are quite remarkable, and at the end of the series is a fully rendered gun that you can toggle in any position...which can in and of itself provide hours of entertainment. I would love a colored version of it fed into a nice screensaver. I never did find what I was looking for. If anyone here knows CAD...please chime in. I have a wonderful awful idea.
Some guys can really make them look real! Amazing
