I am surprised that you said no stamping of the barrels. If you look at the front of the form 6, you will see in red ATF stamp. It clearly says that the barrels must be stamped. On the back of the from 6A The green form that must be sent in after the gun clears customs, it clearly says that you have or will comply with stamping of the barrels in 15 days. By signing this the dealer is certifying that this has been done or will be done in 15 days. This is a federal law that if he does not do it, well you know
