OK, for someone who's not overly into AR's, how do you know if it's a pre-ban or not.
I've got an AR that I purchased in the late 1980's - early 1990's that I have wondered if it is a pre-ban or not. It came with a threaded barrel but no bayonet lug. The box(which I still have, by the way) has a blue label.
So, what do I have?
