Private citizens in most places
can sell short guns to each other as long as they both have a residence in the same state. (notice how I wrote that) Most internet sales are between folks from different states and that's where the law gets crossed and an FFL at one or both ends is needed. In most states if you find an internet sale in your own state then yes you can do the sale with out an FFL. The only potential problem is with the shipping of the gun... often when you declair it with Fed-x they are going to want it shipped to an FFL, and then sometimes they want it shipped by an FFl. Then again, FFL's can just mail the gun using the U.S. postal service. Problem with using an FFL is not so much the paper work on the recieving end but that they all are going to charge $15-$50 for their time. I don't blame them for this, but it kind of changes the end price of the gun.
