After the positive feedback I received in my previous thread, I think I'm going to take the plunge on a M203. I just had a quick question on the transfer, which will dictate which FFL I use. I plan to buy the title 1 receiver, and then the barrel after I form 1 it. When my FFL receives the M203 receiver, how will they classify it? Is it a pistol....rifle? I assume it's not listed as a DD yet, correct? Thanks.
