I love the show, and this episode is no exception, but I'm really sick of Hollywood writers talking about unregistered weapons. Very few places in the US require rifles or shotguns to be registered, and only a few states require handguns to be registered. Pennsylvania is not one of them. Pennsylvania does NOT register weapons, at all. They have a law forbidding it.
And... except in Philadelphia, Pennsylvania allows unlicensed open carry of handguns, and licensed concealed/automobile carry.

The hand grenades the sheriff found in the basement are an entirely different matter. Those are illegal just about everywhere. And if those black rifles were fully-automatic, instead of semi-automatic, they WOULD need to be registered under federal law.
