This is the fruit of the "bump [fire] stocks are just toys" stuff. ATF is once again abusing its regulatory power to piss all over the Constitution and your right to keep and bear arms.
What these regulations essentially do is allow ATF to make criteria it can use to define certain braced AR pistols as SBRs (Short Barreled Rifles). Thus, if your "pistol" is too much like a rifle (say it's an 10.5", 11.5", or 14.5" barrel) they will say it's too long and heavy to be a handgun. The worst part is that this criteria is likely to be fairly arbitrary and subject to ATF's ever-changing whims.
Nevermind the fact that the entire reason short-barrel rifles and shotguns are NFA items is because the National Firearms Act originally intended to ban handguns and thus sawed-off long guns had to be banned too. The NRA just didn't push to remove the barrel length restrictions from the NFA. There is no reason at all that these weapons should be regulated at all.
The ATF is only doing it because governments by their very nature hate armed citizens and regulatory bureaucracies have to regulate. Literally because SBRs are regulated, the ATF feels it "has to" regulate the AR pistols. I don't even need to start in on the leftist and Biden/Harris plans for total civilian disarmament.
If the ATF offers amnesty SBR registration for your braced AR pistol, don't take it. You are asking the ATF "eat me last." If you give a mouse a cookie, he'll keep coming back for more.
Registration will require dong mountains of paperwork, getting fingerprinted, and asking permission from the ATF (sending in another form) any time you want to take your SBR'd-AR pistol out of state, if you move, or want to change calibers.
Second, Biden/Harris have already floated a $200 tax on semi-autos; why tell the goverment what you own? What's to stop them from passing a new tax law that you aren't exempt from or them making that $200 tax annual?
On top of that, then they definitively know you have a firearm in a database that is instantly searchable. As it stands, if the ATF wants to know if you own a non-NFA firearm, they must do significant legwork to find the ATF Form 4473. ATF would have to get Congress to erase the anti-computerized gun registry law and then manually scan and catalog all the 4473s before they could easily search out who owns what. With the NFA registry, this is a quick computer search.
But hey, you want to keep shooting your gun at a public range or whatever and don't want your dog shot, because you are a "law abiding citizen" so some of you will probably do it.
We need to draw a line in the sand and show the government that we will not comply. Remember that very few people turned in their bump fire stocks. The only large numbers were from manufactuerers and distributors. They can't arrest us all and massive non-compliance denies them any legitimacy in the eyes of the public and other gun owners. Raids on gun owners (especially if they go bad like the ATF's abortions in Waco and Ruby Ridge) will only turn local cops against gun control.
Don't count on the Supreme Court to save you. The rule of law is dead in America. You are on your own. There is no voting your way out of this. "We must, indeed, all hang together or, most assuredly, we shall all hang separately."
To start, when the interim ruling is posted in the Federal Register, comment on it. NRA and GOA will likely have easy forms to fill out to register your objections.
Because I write these statements, I fully expect that the government will try to make an example out of me. When gun confiscation starts in earnest, "tall nails" who are outspoken about gun rights, anti-tyranny, Trump supporters, etc. will probably be jailed on trumped up charges to silence them and terrorize others. "Show me the man and I'll show you the crime," once boasted Lavrentiy Beria, a rapist who headed the Soviet predecessor to the KGB, the NKVD.
And how we burned in the camps later, thinking: What would things have been like if every Security operative, when he went out at night to make an arrest, had been uncertain whether he would return alive and had to say good-bye to his family? Or if, during periods of mass arrests, as for example in Leningrad, when they arrested a quarter of the entire city, people had not simply sat there in their lairs, paling with terror at every bang of the downstairs door and at every step on the staircase, but had understood they had nothing left to lose and had boldly set up in the downstairs hall an ambush of half a dozen people with axes, hammers, pokers, or whatever else was at hand?... The Organs would very quickly have suffered a shortage of officers and transport and, notwithstanding all of Stalin's thirst, the cursed machine would have ground to a halt! If...if...We didn't love freedom enough. And even more – we had no awareness of the real situation.... We purely and simply deserved everything that happened afterward.—Aleksandr Solzhenitsyn
