Ever seen these before (case dimpling)?

Ever seen indentations like these before? These are out of a brand new upper, and are Lake City 2014 stamped. Ejection was to 3 o’clock and everything else seemed normal and functioned as expected.

I’ve seen brass banged in that area, but not perfect circles. Strange. Tagging to learn.

Never seen that shape before, interested in an answer though.

Would like to see a couple close up pics of the case deflector on the upper.

Looks to me like the brass is smacking that front corner pretty hard. I don't have one of those new uppers, but is that corner sitting further out from the dust cover than a normal upper?
