Mike the "Q" is an inspectors mark at Augusta Arsenal.
Don't be thinking I'm an expert about this because I'm not. In fact I had to look this up.
I've been dinking with Springfields, Carbines and Garands for a good while but I'm not that knowledgeable about all of the details, which are nearly countless.
There may be someone who can even tell you who "Q" was, but not me.
