I found this on MeWe posted by a friend.
Reinterpreting regulations in such a way as to make possession of an item a felony is the modus operandi of the BATFE. They did it with bump stocks and they are doing it now with pistol braces.
It is now up to the courts to push back on this. The 5th Circuit Court of Appeals did it with Cargill v. Garland. There are now at least four cases before US District Courts challenging the BATFE on their new pistol brace rule. Fingers crossed that the judges will do the right thing.
