Just in case anyone was wondering, the ATF last month did a press release on 80% lowers, other wise know as blanks. Here is the

Nothing new in the release, but it was good that they were showing a 80% AR15 Lower and what they are and are not looking for when they determine what is and isn't a firearm. Just as info.
