So my brand new Stag model 2 seems to have chrome coming out on patches when I cleaned the barrel after shooting 200rds through it. Is this common and should I be worried about it? I looked in the barrel with a good light and it seems there is a dull look maybe lack of chrome at the start of the barrel riffling.(In a very small area) Not sure but that's what I thought. I ran a bore brush through it then patches used CLP to clean it.
