@Justin Hell: I do have some Big 45 Metal Cleaner, totally forgot I even had it, and I have no use for the Ram-Line stock, willing to sell it if you want it, but I have not removed the hand guard from the gas tube, they are soaking in WD-40 at the moment.
@Phosphorus32: I do not see any import stamp on the receiver, and I don't see any on the barrel under the gas tube, but it might be painted over, if it is there............let me confirm if it has a import stamp and I will post it here.
