Where are you getting your stats? NFA tracker?
I laugh because thats user submitted data and not at all accurate.
And Form 1's, half don't understand the difference between eform and paper form.
I did over a hundred NFA transfers in 2019, Single Shot Trust F4's were processed every bit as fast as Individual and most of the time faster. Traditional gun trusts with multiple members took much longer.
Payment (the checks) are stripped out before ATF ever sees the Form 1 or 4.
More to it? Sounds like you believe in those NFA Branch conspiracy theories.
