Does your 9mm Forged A4 Upper Receiver Assembly (9MM0052BASY) have the area inside the receiver where the bolt cam pin rotates machined? I understand that the gas tube hole is missing.

It sure does. You are also correct in that the 9mm uppers made inthe past 5-6 years have not had the gas tube passage (the first batches from '01 and early '02 did have the passage, so there are some out there). Steve/RRA
