Does anyone here know the details of the XGI? I know it was an attempt to scale up the Mini-14 to handle the .308. I also know there were major fatigue problems and it was not put into production in .308. I read once that it was rechambered in 7.62x39 and marketed as the Mini Thirty. In another forum, there were posts indicating that the Mini Thirty was NOT the XGI and that the XGI is still under development. Anyone know the facts?
