They’re the same as far as I know except there is a fingerprint card for every transfer. Hell I had a Top Secret clearance in the Navy and a Secret with the FAA until I retired but they still want to waste time and money on every NFA transfer.For those that have gone through the waiting to get you tax stamp, what background check does the ATF run that differs from a gun purchase background check or to get your Concealed Carry Permit. I do not think that my background changes in any of those scenarios!
