Thanks Vascar! Lots to chew on in your response, but that's what I'm looking for. I'll start the process of elimination now. I did assemble the upper. I trued the receiver and bedded the barrel with sleeve retaining compound. It was properly torqued when assembled, but I'll double check that. I'm running a standard flash hider and ASC 10 round mags.
