I've sold several guns on-line in a person to person sale. All i did was go to the local post office and make sure i could ship the gun before i tried to sell it. After finding out i could they told me that i had to package it so that there was nothing on the outside the package revealing it was a firearm. I had to leave the package open until the postal worker checked the gun to insure it wasn't loaded and there was no ammo in the package. After i recieved the person's money order i shipped it insured straight to the person's house who bought it and had no problems at all and there was no FFL required. I've also bought several firearms on-line but the person i bought them from was a dealer with an FFL so i had to have it shipped to the local gun shop who also had an FFL. Good Luck!
