We've already said that the AK can be butterflied away. We've also determined that there are several alternatives to the AK that can easily replace it. I've only proven that the Soviet adopting an AR wasn't reliant on german stamping tech. Said tech also did not originate in the MP44 that honor goes to the MG-42 which is still there no? So the soviet still have the stamping technology to adopt into small arms design.
I'm not quite sure what point you are trying to make here anymore?
The point I'm making is there would be no Soviet Assault weapon without contact with the STG44 during WW2, same as there would be no M16 without American contact equipped during Vietnam. MG 42, sure, but not the gas system in the stg 44. That is beside the point anway.
