Went and looked and while he is a member here he has very few posts and most are selling something--be careful here to make sure it is not a communication issue. If it is not then fry him.
I've bought a few things here, ranging from custom rifles to a Mark 4 scope to Jewell trigger and AR-500 plates, so far, all has been good and went very smoothly.
I think Boss has made a good point however, maybe we should screen the folks that are only here to sell something. Most are probably fine, but I'd rather buy from someone who is somewhat "known" and has contributed something to the site other than just selling their wares.
I really hope this turns out good for you, hopefully it's just bad timing and not fraudulent.
