This was a taxing authority case.
However, as more of these items are purchased and kept, they can will become “in common use by Americans for lawful purposes,” which will enhance a second amendment element in the future.
I am not a lawyer.
this affects federal law, not municipal or state law, so you could get in trouble for shorties, or suppressors from local LEO.
this is primarily about what amounts to abdication of NFA, and effort likewise for GCA.
this doesnt apply for machine guns [automatic] or destructive devices.
so FEDERALLY no taxes on short barrel or suppressor, non-prohibited persons can possess these things, manufacture for own personal use. gunsmiths may transfer these items[sell+paperwork] to any non-prohibited person, and perhaps maybe in a while you may be able to cut down a rifle to pistol size.
LOCALLY make sure you are extremely clear, on what your state or muni, will allow. this is only a step back by the feds, not others.
I am not a lawyer, but I am generally interested in firearms and firearms law.
A reasonably good source is Mark Smith on YouTube. He is an attorney.
Hope this helps.
Unfortunately much like "rag with chloroform" or "killer with a black glove" became stock images in movies, "Gun with a silencer means a PROFESSIONAL KILLER" is a pure invention.
So the cops find a gun they can't trace, a dead body, no other physical evidence and frankly that sort of murder isn't typically solved.
take note, both styles require a team, this is not a solo venture if your in business you need cover and extraction, and supports, like a stage magician.
