took it to Rob at bowers today he glanced at it while replacing the gas rings and extractor on the BCG from the used upper and noticed right off the bat the entire DPMS lower is machined off center. right side of the entire thing is thicker than the left by a good 1/16th of an inch I am going to measure exactly at work tomorrow.
Damn, that is not a good thing. I wonder if this was a problem that they had or if it was just a one off. Either way not good.

Good luck with getting it fixed up
