Call Alan he charges 0$ if you buy it from him, problem solved.
He did charge me $150 for the transfer of my sear (I did not buy it from him). However I have purchased 3 more NFA items from him and it cost me nothing. So in the end if I used a C3 dealer that charges for every damn transfer I would have spent more money.
It's simple he has to make a living and anybody in the C3 world should know it is not easy it is a very small market.
The predator can I bought from Alan he charged me $150 I found it on line for $120. If you do the math I don't care what dealer you use the $30 dollar difference would never amount to the transfer fees another dealer would have charged me.
That is just my .02
