I really appreciate the offer and the help RARGUNS. I am gonna take you up on that offer if DPMS isn't willing to help. It will be after the new year however. And jim, I am who you think. You can look at it as well. Multiple opinions doesn't hurt.

Is this a factory complete DPMS rifle? From the grouping and erratic nature it appears the barrel may dancing around. FWIW I have pulled barrels off of DPMS rifles and the barrel nut was finger tight!
Check the simple things before you get too crazy. Holding the rifle very firmly(a helper is a nice thing) grab the FSB and try to rotate/twist it. If you detect any movement check the bbl nut. It should be torqued to 40 ft lbs and if needed tighten additionally to line up for the gas tube. Do not exceed 80 ft lbs.
I would re-install the barrel, checking fit of barrel to receiver and the square of the mating surface on the front of the receiver to barrel.
I would also pull the FH and check condition of the muzzle/crown. If it is the least but questionable I would re-crown it.
If you want I am about a 25 minute drive and for me to check it out and correct the issues I mentioned it would cost you less than shipping it to DPMS.

The rifle is a DPMS complete upper on a Rock River complete lower. Here is a pic of the rifle with iron sights:
How does one check the barrel nut? I know nothing about taking apart AR15's beyond what is required to clean them. The muzzle crown has been checked by a gunsmith at Rocky Montain Shooters supply. It was in good condition. I'll let you all know what DPMS has to say and whether they will ship it back on their dime. I know Springfield would pay to ship their firearms back under warranty.
