BB guns aren't covered under the second amendment?
They are not considered arms suitable for militia use according to U.S. v. Miller, 307 U.S. 174 (1939)
The case also made clear that the militia consisted of "all males physically capable of acting in concert for the common defense" and that "when called for service these men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time." In setting forth this definition of the militia, the Court implicitly rejected the view that the Second Amendment guarantees a right only to those individuals who are members of the militia. Had the Court viewed the Second Amendment as guaranteeing the right to keep and bear arms only to "all males physically capable of acting in concert for the common defense," it would certainly have discussed whether, on remand, there should also be evidence that the defendants met the qualifications for inclusion in the militia, much as it did with regard to the militia use of a short-barrelled shotgun.
