I’ll bet that caused an uproar. Mind you, the AK-47 was replaced years and years ago. First by the AKM, then in the late 70s/early 80s by the AK-74. The big difference between an AK-47 and the AK-74 was the round each fired. The original AK fired the 7.62mm x 39 round, an “intermediate” round midway between a full length rifle round and a pistol cartridge.
The AK-74 fired the 5.45mm x 39mm cartridge, which is very similar to the US 5.56mm round.
Still, the basic design of the action is over 60 years old.
