I'm looking to sell a pistol to a friend who is a resident alien. We are both residents of Oregon and he has been here for at LEAST 8 years. I will be making up a bill of sale because he is naturally paranoid about owning a gun without some sort of "papers" to prove he acquired it legally. I KNOW that resident aliens can own firearms if they go through an FFL. My question is, Can he legally purchase one FTF from a private seller without doing a bg check like a citizen can? Thanks in advance for any help.
