I went back to the OP and I still think this is early unlock.
An additional detail dawned on me when researching the barrel itself... I can't seem to find it sold and not include an adjustable gas block. This seems to reinforce my suspicion of early unlock since the port diameter may be oversized with an expectation that the gas system would be appropriately adjusted.
