So I had someone ask me this "NFA question if you know the answer. I have a SBR thinking about selling it. If I send a letter the the NFA making them aware that i am taking the stock off and putting it back in it's original pistol form and seeing if it can be removed or declassified as a NFA item. Would I then be able to polish out my NFA engraving and sell it as a pistol or do I have to keep the engraving?. It's a Arsenal SAM7K" Since this is an AK I am not aware of any other option. I know it is a waste of a stamp. Does he have any other options???
