Since it's a lower receiver for a rifle, it's a long gun. You can ship long guns via USPS.

Just put it in a non identifiable box and make sure you don't say what's in it and you will be fine.
They dont look for "minor mistakes and then pounce". Dont lie, fill out the forms correctly. It is not rocket science. If you have been arrested before it will show up. Get any record expunged before you apply. Put down every address where you received mail. NJ gun owners information is private.
I've been reading around the site and others and I was hoping someone could clarify on what my best option would be.
I've sold off most of the collection and I'm really just planning on moving over with a compliant lower and then buying a compliant upper once I'm settled in. I'm flying into Newark in the next few weeks and I was thinking I could just check the lower but I'm flying in on a Sunday and staying at a hotel that night before getting the keys to my new place on Monday. It seems like the hotel wouldn't be covered under the exemptions so I'm not sure if this would work.
I thought about shipping it to myself through USPS but I don't think I can do the lower because it falls under "other firearms capable of being concealed on the person" under the USPS rules. UPS & FedEx are out because they only allow FFL to FFL.
Do you think staying at the hotel for one night would cause an issue? If so, would my best bet be to just buy the compliant upper now and ship the entire rifle through USPS to avoid any issues?
Thanks in advance!
