Correct me if I am wrong, but the only things that make an upper pre-ban (even if it was manufactured yesterday) is if it has a threaded barrel, flash hidder, bayo lug, or a combo of the above. Now I'm just learning about AR's, but I got confused by a guy at a show selling a pre-ban bolt carrier. Does such a thing exist, and even if it does, is it important?
I was under the impression that even if you have a pre-ban upper, you could make it post-ban by just changing the barrel. Or am I the one who's wrong?
Thanks!
