That’s like saying cars can’t come with steering wheels.
but.. if a supressor is ruled to be NOT a firearm...
I think a lot of the ATF’s and gov’s view of things gets quickly tossed out the window.
Up to now.. MANY items have been ruled as guns or bombs by ATF. a bent piece of metal, by itself, unconnected to anything per ATF IS a Machine gun. That crap under your kitchen sink, used to clean that sink, IS legally a bomb/ unregistered destructive device..
If that “solvent trap” or muffler pipe is NOT a firearm, but an accessory. Then constructive posession becomes a lot more difficult. constructive posession, to make. a fire arm accessory? And as parts/ accessories, not guns. It could give a lot more leeway to states to handle regulation.
