FWIR from SAR article:
According to ?Higgins? of Hard Times Armory, the language is in the '86 FOPA to allow transfers. The FOPA gives exemptions to Military, LEO and "gov't approved" entities. According to ???, this should include EVERYONE, as Form 4's and 1's are gov't approved.
As I remember, he didn't make to SCOTUS, as money and will power gave out.
If the ATF decided, they could accept Form'4 as is for Post 86's. Then it would be up to HCI or who ever to sue to SCOTUS to stop it.
I understand it won't happen, but I can dream.
(I'll try to find the reference on Bardwell's site.)
