Debating what is and isn't an "assault rifle" is irrelevant. 2A confirms a liberty, it does not define a privilege.
At all points in history, being an armed individual has meant being equipped in the same fashion as the government, i.e. military/individual soldier.
The overwhelming majority of weapon designs are founded in military usage, from muskets forward, and this is ALWAYS what the citizen has chosen for arms.
If dumbass Leftists existed in 1873, would they have insisted that citizens must use flintlocks, and could never have the Colt SAA?
Yea, that "SAA" means "single action ARMY", moron.
