In practice, yes, but not in the laws themselves. There are a lot of local attorneys that use that "weapons of mass destruction" clause in the law against us. I don't have NFA items myself (would love to), but have a good friend with SBR's and suppressors, so I've heard stories.
I've also been to Perry's. The head guy there is a moron.
Really. I've had good experiences at Perry's guns, and have bought a lot of ammo there. What happened with the head guy?
Without going into detail, the store owner is one of those people who, because he already knows everything, has no reason to listen to you.
