A friend of mine back in the day, a mechanical engineer, and a couple of his friends pre-ordered the XGI. After waiting patiently for some time, He called the Ruger plant at lunch one day and just asked the guy who answered the phone about it. The guy who answered the phone knew a lot about it and talked to my friend at great length about the problems they were having. My friend thanked the guy for being so informative and honest about their problems and asked the guy's name. It seems that Bill, himself, had happened to walk through the office that day during lunch when most everyone was gone to lunch, and had answered the phone.
As I said, I'm no expert on the Mini-30 but I'll never forget that story. I know it to be true but I know you don't know me so, take it for what it's worth.
I bought a blued rifle as soon as they hit the LGS and traded it in for a stainless version as soon as it was released. Still have it.
Flipflop as found an ad for the XGI. Very cool. http://www.rugertalk.com/forum/f13/xgi-308-a-700/
