We sell them where I work. The ones we have in stock are not blued, but have a coating. Don't know if they changed it or what. Just to make sure, I will check it again tomorrow when I go back to work. If I am wrong, I am wrong, but I have looked at those guns several times and would almost swear they are coated. But you have me doubting myself, so I will check again.
And, we may be disagreeing on what "blued steel" is. My 580 series Mini 14 is blue, but it is not what I think of when I think of "blued steel". That is, the real bluing that all gun makers used to put on all their blue guns. My Mini 14 I can touch the barrel all day long, and it will not leave any fingerprints or rust. So, yes, it is blue, and it is steel, but it aint the old time blue.
