Boy, these people are ignorant. You still have to submit paperwork to BATFE for the tax stamp. BATFE does the background check and takes several months, at least, to give approval or reject the applicant.
They basically run the trust document past the legal staffers to make sure that it is drawn up properly for your state of residence. The actual paperwork is tricky and requires you use an attorney who has done this before. Don't try to squeak by with legal zoom dot com, it will come back to haunt you. Plan on spending about $1000. Of course it will last for a lifetime. I've got one as well as a revocable trust to hold all my assets (including my non NFA items). So sue me, I don't own a damn thing!
