Mossberg 590 abnormal wear?

[u/MacAttack109]

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.

just looks like finish got scratched off. That part should be lightly lubed anyways so its no big deal, i would think.
