Got my upper today. Its cardinal forge marked. The only issues I can see are the T marks are a little "squiggly" and the finish behind brass deflector is a little rippled. I don't have a problem with either. This is going to be a total beater rifle. It might even get a coat of krylon. I'm debating a 5.45 or going with one of the cheap unfinished $70 5.56 barrels that are out there. I'll see how it fits one of the DM blemish lowers from Rguns later tonight.
