A 28-year-old felon was arrested in Portland for trying to sell firearms on Facebook.
Police say an undercover officer arranged to buy the guns.
Four guns were seized in a raid Wednesday, and Kyle Quinn Cully was arrested as a felon in possession of a gun. He has previous convictions for kidnapping and coercion.
KGW reports Cully said he was trying to sell the guns for a roommate.
