Default Barreled Receiver will not pass tilt test

Looking for advice before I give up and part it out.

I purchased an HRA barrel receiver in Feb 2016 from somebody on this form who had purchased it from the CMP years prior. It sat around for a while before I collected all the parts to put it together. After I finally got around to it, it will not pass the tilt test with the lower band installed. I have tried with a couple different lower bands including a brand new one off a CMP stock set. I have tried several different op-rods to include a couple off perfectly functioning rifles. I have also tried it will three different gas cylinders.

No lower band, it passes the tilt test. With lower band it fails.

I am hoping I am missing something obvious, but I am beginning to believe the barrel might be slightly bent.
