Nowhere did I claim it was a reversed engineered anything. People who like to point at Schmeisser, who I clearly eliminated, are the ones that treat the AK as an "updated MP44." Didn't do that. It isn't. It's generation 3.Ignoring earlier developments:
Generation 1: MP44.
Generation 2: Großfuß Sturmgewehr, Gustloff-Werke Sturmgewehr, Mauser StG 45(M).
Generation 3: AK-47.
I'll cover that and the information on the generation 2 guns in the rewrite as it's significant.
I didn't do my normal level of research but that doesn't mean I didn't do any.
