From what I have read, these are all pretty much the same gun. Can someone key in on this and direct me to a website or discussion that goes more into depth regarding this?
From what I remember, I think the M4 can be semi-auto,select fire (3round burst.) or full auto. The AR15 can only be semi-auto, and the M16 was full auto, but much heavier.
I'm sure I will get flamed for this post, but hey, I gotta start somewhere right?
