On the AK issue, your typical AK-47 has maybe 3 or so represented manufacturers in this mod, based on the color of the wood.
IIRC ,just based off today what I have seen:
47
AK
AKM
AKMS
74
AKS
AK
AK:
101
103
102
107
105
RK 95 TP ( You ought to recognize that'n)
and a few others.
It's mostly a case of accuracy but some do a wee bit more damage than others (even within the same caliber)
