Of course any answer would be speculation, but what might happen to those forms that have already been sent and are being put into trusts? I sent one in a couple weeks ago, and did the same as I always have hoping it might get grandfathered, but I'm hoping worst case senario is I get it back as an error and I just have to get the sign off, photos, and fingerprints
Well, there's a strategy for transferring a NFA item via trust without actually transferring it. In the same neighborhood as you, Monterey, You can add another individual to your trust (giving them possession rights) then write yourself out, giving them sole possession rights without the 9+ month wait and associated paperwork.
I think in both cases, they would view it as "tax evasion" and would sic their IRS dogs on you. After burning down your house and shooting your own dog, of course.
