Opened up in the same shop TTI is in near/at Ashland, Va. I've had some rifle work done by TTI. Great work, no issues.
As far as Predator goes all I can tell you is the people setting up the displays/filling the racks, etc. when I was up there to pick up my last work/carbine Rick worked on used to be (may still be) at the local gun shows.
Don't know their names. The lady (wife? partner?) is short, dark haired and has a teeny tiny dog so small you don't think it's real till it moves, barks, or something. If you've been to any of the Richmond or Doswell gun shows you may remember seeing their tables or talking to them.
I don't remember if I ever bought anything from them or not but I did make a remark or to about that tiny little dog at one show.
I've had Rick work on a couple guns for me (yeah, I know, said that already) and I don't think he'd be working with people he didn't think were good people.
