Don't expect a written response from BATFE NFA branch for 12-24 months.
Do you think it would be safe to sell the original 5.56 upper before receiving a written response.

I do not even have the rifle yet. There was a problem with my trust and the NFA agent in charge of my application said it was a minor error where my name and trust name were both filled in and it only needed one or the other. She said it would take about a week for them to send it to my dealer, the dealer to correct it and send it back. That was about 1 month ago.
