It is hitting the brass deflector on the way out of the weapon. You can trim 1 or 2 coils off of the ejector spring should alleviate this.

Post a photo if you can.

If the brass is tagging the deflector, it's kind of normal.

If the brass is hitting the back of the ejection port, this is not normal, and the recever extension is not screwed all the way in to prevent the back of the bolt from going past the rear of the ejection port (read bolt face should stop about 1/8" to 1/4" in front of the ejection port with the charging handle pulled all the way back).

it is hiting right where the  ejection port and brass deflector meet...another guy at the range had an out of box bushmaster his was doing the exact same thing except his brass was dented even more than mine

if you were to stand the brass right up (primer on table top)it would look as if you were carving a minus sign right near the middle

Dented brass is what you want to see, and that's a good thing... It shows you that everything is working properly... With that said, you will not have failure to extract or dropped extraction issues...

I don't recommend tampering with the extractor or ejector springs, that will only lead to problems...
