Is this a damaged crown?

I can't imagine how it possibly could........................? Other than the tiny rub/ding has there been any effects (such as your POI has changed and you've been searching for a cause and this is the only thing you've found?) Really, I don't know how you even noticed it.....................
It's the inner edge of the chamfer that will effect accuracy, you should be fine. Unless the ding is deep enough to deform the edge into the bore, but doesn't look like it does in your case.
I just bought it, its used and has about 200 rds though it.
At what point does it affect accuracy?
ETA: just read above post.
Is there any way to check for a damaged crown?
Yeah, just look at it. But if it shoots good it doesn't matter. EX: If I had a 1/4MOA rifle with a crazy looking crown I wouldprobably leave it alone.
Hope it shoots good for you. Is that the AAC SPS?

Got a Vortex 5-20 and a KRG Xray stock. Just waiting on the rings.
I would think it would depend on a couple things.
How good it shoots to begin with, and if what we're seeing is raised.
If the rifle shot MOA groups before, it probably still would as any increase would hardly be noticeable.
If it shot .24 MOA groups before, it might noticeably affect it, because.......
If that is a raised bur or a portion of it is raised, it does not have to be on the inside edge to affect bullet flight if gasses are being disrupted or deflected back at the base of the bullet while exiting the bore.
If it is just indented, probably no effect to accuracy.
Bottom line, as others have said, just shoot it and see how it does.
If it bothers you, it should dress up easily.

It is not raised, it looks pressed in or missing some material. not sure if this is from the factory or not.
I agree with that. If it's not a burr over the opening, I would ignore it. If the rifle shoots like a dream, I would DEFIANTLY not touch it.

I have read multiple reports of a damaged crown NOT affecting accuracy. The solution is to shoot something BEFORE complaining about the accuracy.
