I just bought a CZ 858, I noticed there is a stain or something in the barrel, breach end. I have added these pics, taken from the mag. side looking into the barrel. What could this be from? It did not remove with cleaning, I don't believe it is rust. What could it be?
( I hope these pics turn out- first attempt)
