I called the NRA legal department and they said there is NO need to have a FFL to work on guns. I seem to have a lot of shotguns coming to me so I was concerned. They also said "You must have a FFL to recieve a gun to work on from out of state." So don't ship or recieve work out of state and you are good. There was no charge from the NRA legal staff and I believe that they are on top of gun law so check with them.
