I purchased a brand new Colt EPR AR and took it to the range a few weeks ago. I shot about a hundred rounds through it. When I went to clean it after the range I ran a bore scope through it and noticed what appeared to be scratches or dings in the lands... I've attached pictures of some of the spots... This had me concerned, but recently I took some pictures with a flash light shining through the muzzle thus acting as a backlight. I discovered that those portions that at fist appeared to be scratches or dings now look like RAISED areas... These marking are mainly focused toward the beginning of the barrel before the gas port. Do these markings look concerning to yall? What do you think they are? Is it super heavy copper fouling??? If so, I haven't ever seen it act like this before... I've ran a bunch of hoppes and boretech copper remover through it, and have done tones of brushstrokes through it, but its still the same...
here are the pictures

The rifle I bought has the "Davidsons life time guarantee" Do yall think I should try to send it in to get replaced?
