I've worked in the firearms industry for 10 years. We manufacture NFA items and this has been asked of the ATF in similar setup for YEARS. The $200 tax you pay goes to US General Funds and $0 goes to the ATF budget to pay toward transfer processing. The whole NFA branch is a waste of time and resources. In my experience they're inept, lazy, power hungry morons wasting agency funds while interpreting laws with zero oversight to fit pump up their ego.
