I have a friend who may be moving to New Jersey soon. He has a CCW here in Oklahoma and we know NJ does not recognize reciprocity w/Oklahoma. He owns a couple of pistols, an AOW Remington 870, a Browning shotgun, and an AR-15. Here are my questions: 1. Can he own his AOW 870 in NJ? If so, are there any restrictions? 2. Can he own an AR-15 in NJ? If so are there any restrictions? 3. Can he obtain a CCW in NJ? 4. Is there any type of NJ registering he will have to do with his guns?
