All that "new rules" are dump and unconstitutional.
If all those contraptions, we call pistol braces, if the ATF said they are legal, then of a sudden became illegal.
That means:
1) ATF passed a law to outlaw the ownership of said contraptions.
Or,
2) The ATF was committing "something" and deceiving the people of the USA that said contraptions were legal.

Both cases should not fly in a court of law.

On the other hand, if an "accessory" for a firearm was being introduced to the market and the Co. behind the device requested a classification for the new the accessory, the initial classification might be considered to be under the jurisdiction of BATFE.

The rule says, the owner can remove the Brace. It does not say the user has to destroy the brace.
