I will provide a couple links when I locate them but I seem to recall an inquiry where the ATF director was grilled about the implications and legal ramifications for anybody who is in possession of a braced firearm and I distinctly recall the director saying that all anybody had to do to be in compliance with the recent rule flip was to remove the brace from the buffer tube/reciever and the director was quoted as saying "all anybody with a braced firearm would have to do to be in compliance would be to remove the brace device from the buffer tube extension". Pretty much verbatim.
Now, it seems that the most recent, as of yesterday I think, there is a new letter that says that the brace must be removed and destroyed, or altered so that it cannot be re-attached.
It's very bad communication and typical of a government agency, but it's also very irresponsible to flip flop back and fourth on an issue time and time again such that anybody who was listening to the directions straight from the director as to how to be in compliance last month, but didn't keep apprised of the issue could potentially face a felony charge, prison and massive fines.
Is anybody holding out for an injunction or yet another rule change or is everybody basically resigned to the grim reality that these government agencies are basically free to impose laws and regulations totally absent of congress.
I will post links shortly, apparently a new letter came out this week that would contradict the directors claims from April. It's frustrating, I know of alot of simple folks who aren't going to comply or even know they are in violation because they just don't keep up and don't have their noses buried in their phones or talk guns or politics, it just isn't reasonable imo.
