I just got my ACR and had it apart and noticed that the gas regulator doesn't have a hole drilled in the S side and was wondering if that is a mistake. It has to go back for the recall anyway so figured i would ask now. Thanks
Nope, your good to go. The "S" side hole is actually on the opposite side. The gas relief port is on the front of the gas block, right above the barrel.
Bottom line, it's normal and good to go.
