This is a papercraft AKM model I originally made for /po/. It's rather large (1:1 scale), and can take a while to build because a lot of the parts have walls on the inside, for sturdiness. The safety and bolt are moveable. If you want, there's space to put a spring to push the bolt forward, though the strength of the spring vs. the strength of the parts would be your concern.Download Link (Mediafire)
As of November 2013, the V2 iteration of this model
is now available, offering a greater level of detail.
