The STG-44 and Ak-47 are both gas operated and piston driven. I was wondering if anybody could find and post the schematic diagrams for each, as I believe we would find that they are rather dissimilar in most other aspects.
From what I understand Kalashnikov used a rotating bolt, the idea for which he got from the Garand/Carbine line.
Ooohh BigBob, I'm afraid you've opened a can of worms now.

Awesome thread though.
