Lets say i want to buy an AR from out of state and of course it has to go to an FFL here. The seller wants to throw in a "spare" adj stock and the rifle already has a mounted A2 on it Technically the FFL could not let me take home the adj stock as that would put me in constructive possession. Is that correct?

edit- dont want the adj, was going to sell it, if I could

Assuming you had it shipped to an FFL, the FFL could pin the stock for you then your ok.

 

An AR falls under long guns, so you could drive out of state and buy one then drive it back into NJ. I know some shops in PA, Cabelas being one of them, won't sell a NJ resident anything with the "evil features". Not trying to stir the pot here over legalities or moralities.

Must buy from a dealer, not face to Face out of state

To answer the original question, have the out of state FFL ship the rifle with the A2 on it to your NJ FFL.

Have him ship the extra adjustable stock directly to you. It's only a part, not a gun.

All 100% legal

Yes, it's legal as long as the rifle sits at the FFL until he sells the stock or pins it. Otherwise, as he stated, that's constructive possession.
