Here's my 2 cents worth. The bill of rights applies to all Citizens, whether they are crazy, criminals, or law abiding citizens. It doesn't say anything about not applying if you are nuts or are a criminal. If I'm armed, I can protect myself from the Nuts and Criminals. Next, I bumpfire my unmodified carbine all the time. I don't need a Bumpstock. As to the age thing, I think whoever came up with that one should whipped with blacksnake(another name for a bullwhip). You can join the Military at 17 with your parents signature, 18 without. So you can join the Military, be highly trained in weapons use, go fight in a combat zone, get your ass shot off, shoot somebody else's ass off, win the Congressional Medal of Honor, come home and can't buy a rifle? What the Hell kind of thinking is that? It makes me want to just slap the shit out of a Liberal.
