it's on a upper.  I see some on the carrier too.

It's hard to see the top two in your picture but they look like to-be-expected wear from the CAM PIN.  The bottom arrow looks like machining marks to me, not wear marks from use.

If you haven't experienced any functioning problems don't worry about it.  They will wear to a point and stop.

I'm having a real hard time seeing what I need in that picture, I think part of it is my monitor too.

Those wear marks seem normal to my untrained eye.

Its eventually going to wear a little more than that, but don't worry about it.

Mail that old upper to me and go buy you a new one !   ...You can expect a little wear !

reason i saw this is, because on my BM lower, i've used twice the amount of ammo, and it's not as worn down as that LMT upper.

Just making sure it looks fine.

Looks normal to me. Metal on metal will make marks. Doesn't matter what lube you use, friction can be a good thing....(insert punch line here )
