I found it when I was looking for a Regent BR9. They showed one in stock at $479. That one was believable. I called, got the message, hung up, and got the call back. I didn't bother looking at the rest of the site.
These guys are posing as a gun shop in Marietta, GA. The site is fake. This business doesn't exist. When you call them, you get a message from Google voice. After that, the number will call you back, and some foreign guy, claiming his name is James, will repeatedly ask you if you can hear him...
