I can say as a dealer, many dealers dont know the law. I sell on the internet and get buyers that have dealers refusing to send me an FFL unitl I send them a copy of mine. When asked why, they say that they want to make sure I am an FFL before they send theirs. I guess they think someone will do ?????
I have had other dealers try to tell me that a mauser reciever doesnt require an FFL. "its not a comeplet gun" they say.
I could go on. Same for UPS, Post office etc. too many people dont know the law.
I sell and ship to C&R all the time any gun that meets the criteria.
Very frustrating at times.
