i dont believe there are any banned uppers. nothing they can do about uppers that would cause a rifle to be banned until its installed on a lower. according to the atf uppers are just parts until they are installed on a lower, as far as i know. if not someone enlighten me.
not a dig, just trying to figure this out for myself.
Yeah, I changed my wording to "pre-ban" to avoid confusion. We can buy whatever uppers we want, NFA aside. It's just illegal to put non-HBAR (pre-ban) uppers on a post-ban lower within MD boundaries.
