The tax stamp process has been greatly reduced from many month to less than a week if you are interested.
I saw a recent interview with a former ATF employee, he said that the NFA crew validating paperwork went through a complete cultural overhaul.
A new head dude was installed and he started getting death threats from employees that didn't appreciate being prodded to doing actual work.
Grind through the government process of relocating them elsewhere or letting them go, eventually productivity was restored.
He also pointed out that trusts take longer because they have to have the legal team verify it is a valid trust. Too many were "pulled from internet" and wouldn't hold up in court if it came to that.
