If a forum member has been unable to sell his Used suppressor for who knows how long. What would a NFA TP section do the ones already in place do differently.

There's also the people not familiar how to sell an IN state NFA item person to person. No matter how many times someone ask (again) in every forum besides the correct one.
Which relates to my first sentence, considering the OP of that For Sale item Had no clue how to do an In state Person - Person sale.

Just put NFA in the subject line and call it good.
