NJgunowner,..Are you sure about needing a FID card to purchase a long gun in PA? I bought a 22 a few years ago at a gun show from a dealer (they did a NICS check) before getting my card and there wasn't an issue.
Then both of you broke NJ state law. You CANNOT under any circumstances buy a gun while living in NJ without a FID. If you LIVED out of state and brought it with you when you moved here that would be fine. If you inherited it, that would be fine. But as a resident of the state buying a gun without a FID is a no no.
