If you Form 1 an AOW, does it come back with a blue stamp?
I don't know. I think mine is red.
This^^^^^^You find a dealer or person with one that you want to buy. You pay the dealer or person for it. You submit the Form 4 to ATF. When the Form 4 is approved, you can take the gun home. If you build one yourself, you must first start with a "pistol grip only" shotgun. You submit a Form 1 to the ATF. When that Form 1 is approved, you can build it to your liking. The difference is that a Form 4 for transfering an AOW is $5 and a Form 1 to make it yourself is $200.
