Um... one problem with that. There is no paperwork required presently unless the firearm falls under NFA restrictions. Heck, there is no requirement to notify the ATF at all if you want to build a title 1 firearm.

However these notices are not required to be filed by convicted felons, as that would violate their 5th. Amendment right against self-incrimination.
Well, crap! Then it is a casse of "creeping crud". Thanks for the correction.
