Before I got my FFL I used to buy shottys and rifles from out-of-staters all the time. No problem.
If you want to cover yourself, send it to an FFL. Then it has to be transfered(registered) to the new owner.
If something illegal occurs with a gun registered in your name, you will get a visit from LE.
For those that think that a rifle or handgun, that you bought from an FFL, isn't "registered" in tour name, you would be wrong.
Although Oregon is a "no registration" state. Your purchases are "registered"
