Case not ejecting on a fired round

[Stugotz]

I believe I found the root problem. I measured the distance between the edge of where the hole was bored through the barrel allowing the gas to vent into the gas block and to port in the gas block. If I seat the gas block against the the shoulder of where the gas block seats against the barrel the gas block port extends beyond the barrel port by approx. 1mm. (Please see the attached pix.) I tightened down the gas block 1mm prior to where it engages the shoulder of the barrel and it centers over the port on the barrel perfectly. So who is at fault? The gas block manufacturer for incorrectly drilling the port in the block, or the barrel manufactured for incorrectly drilling the gas port in the barrel 1mm further down the barrel (closer to the muzzle of the barrel?!?[ATTACH=CONFIG]18346[/ATTACH]
