Call your FFL and ask what they would charge to ship it. I sold a pistol and both UPS and FedEx wanted over $100 to ship it. I do not know about long guns but USPS will not ransport a handgun mailed by an individual, but FFL can mail them. I went to my FFL and he’s hopped the pistol for me for $25 plus the Priority mail fee. But do check USPS, I seem to remember you can ship a long gun, but could be wrong.
