You are just that simple-minded. Franklin and Jefferson were engineers among other things and understood the progression of the hand cannon 1300AD, to the firelock, the matchlock (think 3 Musketeers), the wheel lock, the shaphance and then the flintlock. Some lived to see the percussion lock. BTW, we had BREECH LOADING rifles in the Revolution on the British side invented by Maj. Ferguson.
If you want the tech argument then the 1st Amendment only applies to hand cranked presses not TV,Radio, Cable or Internet. Bite me!!
