The Second Amendment only covers Muskets

As an early type of multiple barrel firearm, the ribauldequin is sometimes considered the predecessor of the 19th century mitrailleuse.[1]

The first known ribauldequin was used by the army of Edward III of England in 1339 in France during the Hundred Years’ War


Over 400 years BEFORE the Constitution was even drafted, there were rapid firing, multi-barrel weapons.

And I've yet to have any Anti-Rightist's to explain if we were only intended to use muskets, how can they justify using anything more advanced than movable type and messengers.
