| I was looking at the upper i just bought from ya'll and noticed on the barrell feedramps that there are copper looking strikes on them, it is not black like the rest. Is this normal? |
I thought that, but then I looked at all of my other uppers and none of them have the marks there. I'm really not to worried about it, just thought it was kind of odd as I have never see that before. |
