Most of you have heard the oft-repeated lefty comment that the Founding Fathers, in writing the 2nd Amendment, did NOT intend for civilians have automatic weapons. Or, they claim (again falsely) that the FFs could not have anticipated the technological advancements in firearms.
Well, now you can tell those antis to "stuff it" as there was a "machine gun" developed and patented in 1718 by a British lawyer and inventor. Named after him, it was called the "Puckle" gun.
The Puckle gun (also known as the Defence gun) was a primitive crew-served, manually-operated flintlock revolver patented in 1718 by James Puckle (1667–1724) a British inventor, lawyer and writer. It was one of the earliest weapons to be referred to as a "machine gun", being called such in a 1722 shipping manifest, though its operation does not match the modern use of the term. However, the Puckle gun was never used during any combat operation or war. Production was highly limited and may have been as few as two guns.
