AR brace swapping?

[Drifter27]

I have an off the shelf ar pistol. Id like to change the brace it comes with but dont want the Angry Taco Ferrets (or whoever they are) to deem it something it isnt. I understand with something like a shockwave even having a spare buttock makes it bad news and can be considered intent.

Is there something in writing somewhere saying all braces are equal?

Even if such letter existed, which I doubt, it could be superseded tomorrow.

I put an SB4 slide over pistol tube ( not military OD) one on my Noveske Diplomat Pistol lower at my known favorite fighting LOP for an AR with GLUE ! One less thing to fool with if I need it and adjustable m4 types only save a couple inches. It was $70 , but SB tactical is top quality, well researched legally and works great. Back when I bought the Diplomat pistol from John Noveske he would only sell it with a "pistol" buffer tube that would not accept a military type stock without a tax stamp . If the ruling is changed I could cut off the SB slide on brace with a knife in a minute thus destroying it.

If it says pistol brace I’m good with it. To heck with them.

I'm leery of AR/AK pistols, because you're dealing with an agency that that both doesn't set or respect precedence, nor put out clear established guidelines. Take the Q pistol for example- if you happened to buy one, it was marketed and sold as a pistol, and the maker, dealer and buyer were all engaged with what they understood to be a legal activity. They sold it brand-new in the box and unmodified, you filled out the 4473, you passed the background check... to the casual public buyer, every requirement was satisfied. There may be some folks out there that don't follow this stuff online that own one, that don't even know of the issue. They might have, oh, a burglary 15 years from now, and when things get evaluated and submitted in the police report, you find out you have an illegal weapon. "Wait up, I have the receipt. I bought this at Buds's (or somewhere). What the heck?"

I guess ultimately, they DO have guidelines; 16" barrel and 26" overall length for "a rifle" that can be shouldered.
Same thing with the bump stock issue, you can't own “any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger.” Not without the correct license, and it can't be new production (has to be made before 1986).
Neither the pistol brace, nor the bump stock, technically violate the letter of the law, but the ATF gets to decide if they violate the spirit of the law. I get that it makes for fun hypothetical legal arguments, but the truth is, nobody wants to be the guy fighting that in court.
