In a slight tangent, the worst fuddlore out there about AKs is that the selector goes from semi to full auto and then semi, and that the reason would be because Russian doctrine has the full auto as the main tactic when using the weapon. Anyone handling an AK in any situation outside of a static range quickly realizes that the reason for that order is actually because when you disengage the safety under duress, you hit it quite hard and thus you go to semi, rather than full auto.
