No right is absolute, ever.

You have the right to "pursue happiness" but if you're happy being a rapist, well, sorry you don't have that right.

There's the obvious "You can't yell fire in a crowded theatre." argument, which is technically a "violation" of free speech but a reasonable one, in this case.

Just the same, there are weapon restrictions that are reasonable. I do think that most any type of total ban is unconstitutional however.

Just like in the theatre example it's not illegal to YELL, it's illegal to yell certain things in certain places. It is equally reasonable to restrict certain types of weapons to certain areas, uses and oversight. RPGs come to mind, along with "machine" guns.
