Lots of great arguments, lots of unequivocal proof that the ATF is acting outside of its authority, and still, at the end of the day, nothing will be done to prevent the ATF from doing whatever it wants. There are no repercussions for breaking the rules, whether you’re a criminal or a gov employee/rep/lackey. If you’re a good citizen who is not breaking any laws, though, you’re screwed, because they’ll just make a new rule that says you are, and there’s nothing you can do about it.
Funny thing is..no one is going to register their ARs that have braces with the ATF. The turnout will be about as much as the NYers that registered their ARs under the unSAFE act.
