Ak47
STG44

Russians stole the plans from WWII when then raided a bunch of munition factories. LOOK AT IT!

Actually, the maker of the Ak-47, Mikhail Kalashnikov (the AK-47 is also called a Kalashnikov due to the maker) was inspired by the Russian PPS, yet I don't know whether the PPS was inspired by the Stg44

Strictly speaking I think the Avtomat Federova was the first assault rifle in history, because it had the basic definition of an assault rifle; automatic fire, and a shortened rifle cartridge.

But from what I've read, it was rather underveloped, unreliable, and it tended to jam. I think it does deserve credit as a first attempt, but I still think that the St44 was the first PRACTICAL, soldier proof, assault rifle.

I'm going to have to say, the earlier one doesn't count, the Ariska wasn't a shortened cartridge, it was a full powered rifle cartridge, just on the weaker end of the spectrum, I say that doesn't count, cause it's not, from what I can gather, a deliberately smaller version of a "full powered" rifle round.

Even if the first one may have been produced 40 years earlier the Stg.44 is in my opinion worlds first assault rifle for a simple reason, it was the first produced and used in large scale with success (they lost the war, but wth? all their gear was years ahead of the enemies)
