Misc Mossberg 590 abnormal wear?

Would you consider this to be abnormal wear? This is the first 590 and Mossberg shotgun I’ve owned so I’m not sure what the typical wear looks like. About 150 shells and this mark has appeared on the ceiling of the receiver.

My 590A1 looks the same. Receiver is aluminum, bolt is steel. When it wears in, it'll rub a bit. Just lightly oil that area.

Thanks for the response. I just wanted to get an idea of this is normal.
