What is the worlds fastest single barrel machine gun?

Answer 1

Either the FA-MAS or the UZI but the uzi has terrible Accuracy so the FA-MAS is the way to go

Ummm... Sorry but you're wrong

Although I don't know the answer, I do know that firstly the UZI only has a rate of fire of about 600 rpm and the FA-MAS at about 1100 rpm. The MG-42 maxes out at about 1500 rpm.

However it is worth saying that smaller variants of the UZI have a higher rate of fire to the point that the micro-UZI fires at 1200 rpm
