Actually, there’s still no EO published.
But the ATF has released new “guidance”. Sort of.
DO I NEED A LICENSE TO BUY AND SELL FIREARMS?
Guidance to help you understand when a Federal Firearms License is required under federal law
The guidance set forth herein has no regulatory effect and is not intended to create or confer any rights, privileges, or benefits in any matter, case, or proceeding, see United States v. Caceres, 440 U.S. 741 (1979).
That translates from the Bureaucratese as, “Follow these instructions, and when we bust you anyway, you can’t use us as an excuse. Eff you.”
From what I can tell, nothing has changed. My guess is that someone pointed out that federal law already is very specific as to what constitutes being engaged in the business of selling firearms. But Barrycade had already spouted off so much that they released something “new” to cover his ignorant ass.
Behind the scenes you can expect the ATF to run more gun show stings, bust people who clearly are not engaged in the business, and simply destroy them financially with malicious prosecution. It happened before, and seemed to have tapered off. Expect a major ramp up again. Jarret and Lynch gave the tip off when they said selling even one gun can make you a dealer despite the clear language of 18USC912: “repetitive purchase and resale of firearms”. Be careful out there. They don’t have to win in court; just destroy you. And that appears to be the plan.
