In New Jersey, it is illegal to own an air rifle if it in any way reduces noise. That would make it a weapon with a silencer. Such weapons are illegal in New Jersey.
The police did not bother with this in the past, but now they do. The thought of an air rifle with a silencer is just too scary in the world we live in.
This may sound silly to Americans who live outside of the Garden State. It may even sound silly to most citizens inside the Garden State. The idea that criminals are going to threaten victims with air rifles equipped with silencers is bizarre. But in the world of bureaucracy, North’s law of bureaucracy reigns supreme: “In any bureaucracy, some bureaucrat will eventually enforce the letter of the law to the point of absurdity.” This is an example of the law in action.
So, if you intend to hunt squirrels in New Jersey, you must not use an air rifle with noise suppression. It would not be sporting. It would also be illegal.
I don’t know how gun owners are supposed to comply. Must they sell their guns to New Yorkers? How are they to transport their guns across the state’s border?
