Belton “Repeating” flintlock

The idea of a repeating firearm (a gun that does not need to be manually loaded after each shot) goes back to at least the 1500’s. But more-or-less practical “repeaters” were produced in time for the American Revolutionary War. Such weapons were proposed to Congress, but even though they worked they were very expensive. As well as complex, heavy and likely unreliable in field conditions. but the important thing to note is that they existed, well in advance of the adoption of the Constitution. So anyone who suggests that the Second Amendment only supports ownership of single shot muzzle-loading muskets because that was all that was available… well, they’re (charitably) wrong, or (not unlikely) outright lying.
