I have a question about the upper receiver, What are the markings on the front of the upper before the dust cover?

I have one more question does this lighten up my barrel? haha I remember 9 or 10 years ago seeing this marking and couldn't refuse not to buy.

Your barrel is drunk.

The barrel marks were made by someone who stuttered. Don't make fun of stutterers.
