I'm a resident of Washington and have been thinking about buying a used carbine, either in Washington or Oregon. At least I think that I will be able to buy one in Oregon, if I'm not a resident, let me know if this isn't true. Anyway, buying a used carbine from a private party, during the transfer is a sales tax collected in the State of Washington at the FFL? I would imagine if you were to buy it from a LGS they would charge you the tax. Then if I were to buy a carbine from a private party in Oregon, can it be transferred to me in Oregon at a FFL, if I am not a resident?
