Is autoweapons.com Safe?

The site autoweapons.com does not provide any technical information on their products such as has the part been heat treated, staked,MP mag particle tested and the list goes on. When I politely asked for some help via ***** I was told to f*** off and get lost. After getting that reply from them, I wrote back complaining about the first reply. They replied they had turned my email address over to the ATF (should have sid BATFE). I wasn't asking about any FFL parts and even if I was they shouldn't have said that I need an FFL to ask about the bore of a barrel. I called the corporate headquarters and was told by the the payroll lady " Tuff luck but we don't care what happened. My advice is to avoid autoweapons.com at all cost. They are probably involved in something illegal. Why else would they be so paranoid, rude and unprofessional. Maybe the BATFE should take a look at them. It's your money so it's your decision but with so many good suppliers available autoweapons.com doesn't sell anything you can't get at at least four other sites.
