I don't really have an idea on the AR, but I do know that selling the Tac-16 is going to be a whole big thing. The tax stamp and the current 4 month wait make it hard, and there is not much of a market for used suppressors (especially the ones that are so inexpensive new), unless you give the person a very good deal.
I do agree that the suppresor will be the hang up but also, if I understand correctly,since it is private party transfer, the buying party gets the suppressor while they wait instead of after the paperwork is complete.
I'm no expert, but I would think that this is very incorrect and a good way to get some silver bracelets. But, I have been wrong before.
You are correct, you would have to hold onto the suppressor until the transfer is completed. Until the ATF finishes the paperwork, and gives the buyer his stamp, it is still considered the property of the sellers to the ATF.
Thanks for the clarification guys. Don't need or like those bracelets. That being said All NFA rules Apply...
