A new upper on a new LMT lower. second time shooting it. when i went to clean it for the second time i noticed this. I did a google and site search but i did not know what to look for so i had no luck.

totally normal. like almost all wear, its not uncommon to see what seems like drastic wear in a relatively short time.

See that shiney spot on the bolt carrier just above the clearance channel for the buffer retainer? Stone it down and that wear pattern will stop.
My brother saw Deliverance and bought a Bow. I saw Deliverance and bought an AR-15.
Yep.
I lap the rear of my carriers in a figure eight pattern using oil and an Arkansas Stone.
Take a jewelers file and some emery cloth or fine sand paper, and slightly chamfer the edge of the milled buffer detent channel in the bottom of the carrier as well.
Eliminate the burrs and you’ll eliminate the buffer damage.
ETA: Better pic of another carrier.

Here’s another shot of the carrier shown in that last pic above.
This is after refinishing with G96 cold blue, and about 1000 rds. Take note of the areas indicated by the arrows, and how I chamfered and rounded those sharp edges.
