I love my guns but you're wrong.
The constitution doesn't say must be armed with assualt weapons, and when it was written we didn't even have rifling in gun barrels.
What constitutes well armed is purely subjective. It could be shotguns and long rifles, or just pistols. Could be anything.
Make no mistake if they can have something bad enough happen where they can scare an assualt weapon ban out of people they will do it and it won't be unconstitutional because we will still have other guns.
Wrong.
All rifles always had rifled barrels.
The British were still using the smoothbore BrownBess musket, but the American Continental Army was mostly using rifled barrels, like the Kentucky Long Rifle, made in Pennsylvania.
The problem of rifling is that you had to ram the bullet down harder than with a smooth bore musket.
So to repeat, smoothbore is a musket, and a rifle has rifling.
And NO, what is protected by the 2nd amendment is what ever the best military grade is, because the whole point was to ensure the private citizens were ready to act as the Militia if an army was need to be quickly brought to bear.
The US was to have a volunteer citizen soldier military, and not paid, professional, mercenaries, who can not be trusted.
It is impossible to read the 2nd amendment and not see that any and all federal firearms laws are completely illegal.
We can argue about state laws, but not federal.
The 2nd amendment is a blanket prohibition on any and all federal jurisdiction over firearms.
