Got my new PSA upper, put it on my PSA lower and hit the range. I ran 60 rounds through it and afterwards at home noticed a shiny spot on the uper part of the ejection port. What do you guys think?

I was really hoping that I wasn't missing something.  I looked at the pictures a few times each, wondering what I missed.

Looks like a serious case of AR15 scratchanddentitus. Symptoms include small nicks around ejection port, brass colored marks on shell deflector and scratches on the area where the charging handle locks into the upper reciever. The only cure is to remove the upper and send it to me for immediate quarantine!!!  

Just kidding... Looks good!!!

And before you ask, the wear to the inner surface of the upper (near the space for the bolt cam pin) is also normal.  I can see it forming in pic #1 and #2.  It looks like a small divot in the metal.  It will continue growing for awhile.
