Some parts may be mil-spec, but not everything is. Really the point was that since it was not a Colt or other high fashion brand thats overly mil spec it was automatically written off as crap. There are a lot of DPMS, S&W and countless other brands of guns that work just fine.Very nice "up grade". And nice review. I thought that it stated in the nomenclature that the rifle was "Mil-spec"?
