Can a stock be worked on by a non-FFL guy if you eliminate the shipping part of the equation and deal in person? I can sell a gun from private individual to private individual with out legal trouble. Why can't my Brother-in-law "Otis" make me a new stock for my Stevens 311? I could see the requirement of FFL for someone doing this as a business (one that pays taxes on the income), but the woodworking hobbyist... seems like they should get a pass if dealing in person. That's probably not the way it works in real life.....
