Hello all,

I was cleaning my DPMS upper when I noticed that there are small "spider-web" like cracks when you look at the bolt carrier from the rear (where the firing pin sits).

Is this normal? The upper is fairly new with only 150 rounds are so put through it. Thanks for your help.

Atleast its only the carrier, doesn't sound normal. Need more to go on post a picture.

I hope it's just carbon deposits. I was cleaning with every tool I had for about 45 min with no luck. I will try to borrow a friends camera, mine wouldn't focus on the area. Thanks again.
