I'm not saying the laws make sense. I think the second should be banned, as well. I have difficulty believing that there is a legitimate use for the PCR -- if you need one as a hunter (which is the only explanation for having one I've ever heard), you suck... find a new hobby. I don't think using that kind of weapon for hunting is much different than dynamiting for fish.
