Only the basic concept. The AK is a much simplified design. The German designs were more like our current ones, a bit on the complicated side, with precise tolerances required. The AK, and many other Soviet designs of the period, OTOH, explicitly recognized the inferiority of Soviet manufacturing processes. Many of these "Duds" were designed or built, or both, during the decade or two of upheaval that followed the (temporary?) End of the Evil Empire.
The AK was a stroke of luck. The previous mosin-nagant was a typical shoddy piece of work. Outside of the BMP, the Soviets had crappy equipment. What they did get right like the RPG 7 was stolen again from the Germans.
