Hello all, got my first borescope and used it on a (new to me) AR10 and was told the rifle had less than 100 rounds on it. I know, everyone says that.

But i noticed what appears to be some voids, almost like some recesses in the chamber, seemingly where two metals meet. But i'm a complete novice on this, can i ask for some opinions, particularly starting around the :30 second mark

Does this chamber and barrel look consistent with a rifle with a sub-100 round count?

I'd love to hear people's opinions.
