Is this going to be a problem...or is it normal wear (large pic)

Yesterday while I was cleaning my M&P 15 I noticed a shiny spot on the rails in the upper receiver...there has always been a small shiny spot there...but it has grown some.

Is that normal wear or do I need to get it looked into?

What do you mean by " on the rails in the upper receiver" ???
That looks like you are pointing to the carrier itself, no?

;) Put your glasses on....:)

The bolt is back...that shiny spot is on the upper.

I have a STAG upper that is a little worse than that on both sides of the cutout after about 2K rounds. I had a Army Command Master Sargent friend who is a President's 100 winner look at it and he said "DAaaah! shoot it! I have seen the markings go way back much worse than that"

Relax .......

Yeah, guess I need the glasses. To the left of that white arrow looks like the circular, divot area on the carrier itself. My badzzzz....
