The last two deals I've done, the buyer asked if a BGC was required. I have no problem with the question and both buyers had no problem meeting me at an ffl to do the bgc after I told them a bcg was requires. He later told me that he has traded a few firearms and he doesn't care about the current law. Btw, he was from armslist, and yes he passed the bgc.
I hope one day they reverse the law but for now it's too easy to pay the transfer fee and $10 for CBI. I do find it funny that in a few months I'll be moving to a state where you can private party transfer rifles but not handguns.
