Just nullifying the approved amnesty Form 1s would also create a bunch of actual criminals. I’m betting the vast majority of people who get Form 1s approved quickly replace the brace with a real stock since the gun is now a registered SBR and braces suck for shooting. You nullify those Form 1s and now those people ACTUALLY have unregistered SBRs. They’d be creating the very problem they claimed the rule was meant to address.
