Nuke Road Warrior on Unfortunately his opinion (or mine) doesn’t matter. Only the ATF’s opinion matters. As we’ve seen before their opinion can and has changed at a whim (bump stocks any one?). With a probable Biden administration that advocates a total “Assault Weapons” ban, there will be no restraint on the ATF. If anything this will be used to propagandize the claim that any semi-auto can be “readily converted” to a machine gun. With Roberts defecting to the left, and the SCOTUS’s historic unwillingness to directly overturn ATF regulations, coupled with the fact that this is a new device and therefore not “in common use” I wouldn’t expect judicial relief.
