All I can say is that I tried in multiple emails over a couple of weeks to buy a CA M15A4 rifle from him and I never received any reply to any of my emails to date, and this was from mid-November. I had the cash and was ready to buy, but never heard back. So I just ponied up and went to A&A instead, where at least I was being acknowledged. The gun cost about $25 more there, but the fact that I actually got service made it all worthwhile to me.
Other than that, I have no personal experience in dealing with 007. But people here seem to speak very highly of him as a straight-up guy. And I've learned to trust the opinion of veteran members of this forum.
