With regards to that "biker guy" that bought those handguns, I was told that was Hugh King. I figured the show was staging stuff at that point, and I lost all interest.
Hugh "The Chopper" King is the co-executive producer and master of ceremonies of Discovery Channel's reality television series Biker Build-Off.
A buddy and me actually wandered in there a few weeks ago, after two of the other gun stores we wanted to go to were closed that day. I didn't know anything about them or the show, but was kind of turned off by the guy behind the counter. He came off kind of arrogant; don't even recall of it was the main guy or not. We just left, seeing a bunch of people sitting around not working, wondering how they afford to pay all these people to do nothing. Guess I know now. The only reason we wandered in there in the first place, is because I typed "gun" into Google Maps on my phone, looking for local shops to browse. I literally work less than 5 minutes away, never knew they were there.
