So this question came up today. I'm curious as to what everybody has to say. It's been my understanding that an M14 is selective fire. An M1A is the semi auto version of the M14, but I am told that no; there is such a thing as an M14 semi auto, and that M1A is actually a designation of a Springfield Armory M14 semi auto. So what say you all? Is a semi auto only M14 correctly called an M1A or what?
