In Heller and Bruen, the Court has already expounded on the definitions of every word of the Second Amendment and add a term that trumps your asinine "assault rifle" definition: "IN COMMON USE". If a weapon of any kind is IN COMMON USE for ANY lawful purpose by the citizens of the United States, government at every level under the US Constitution has ZERO AUTHORITY to ban said weapon. The definition in play for the term IN COMMON USE was set on the USSC ruling barring Massive-Two-Shits from banning stun guns amongst their citizenry: ~200,000 to 250,000 in private hands.
Given how many millions of AR platform rifles alone are out there, you stand absolutely ZERO chance of getting an AR ban to pass legal muster, DUm'Rat.
