Well brother, you can do one of a couple of things.
1) You can order a custom gun from a custom shop, like Larue or Sabre Defense
2) You can go to a couple of competition shoots, even if they are bench rest competitions, and ask around who makes the shooters sticks...
or you can shop around the internet for quality gunsmiths who build a good product for a good price and deliver as ordered.
I happen to know a guy who does that, and he has made plenty of weapons for me - but you should do your own research and see what YOU think as opposed to some guy on an internet forum, even if it's me.
