I went ahead and submitted a claim with GB about this guy. I included the GunsAmerica post in it. Hopefully GB responds accordingly before someone falls for this BS.
I went ahead and offered the scammer douche a pickup in Jacksonville for it. Let's see if he bites :-P
GB's response. Although it appears too late as the pistol is marked sold now.
Looks like GB has killed his account. I hope they were able to contact the buyer before he sent money.
