Not Your Average Flintlock

When our Constitution and the Second Amendment to it were written, the most widely-used form of armament was the single-ball flintlock musket.  Even the most practiced marksmen of the time could get off only a few rounds per minute.  That's because the weapon had to be manually loaded, one gunpowder cartridge at a time,  one ball at a time, then aimed, then fired, then reloaded ... you get the idea.

One can, therefore, easily make a case that the Second Amendment could not have conceived of, let alone supported, weapons like a Kalashnikov.  A well-regulated militia, and the rights of citizens to keep and bear arms, doesn't mandate a gun that can spit out 41 bullets in 31 seconds, or one that can support  100-round magazine.

Or any magazine at all, for that matter.
