Squished Rifling?

I got this new barrel. It is nitrided.

The start of the rifling (is there a word for that) looks uneven as if it was squished down. https://i.imgur.com/u3cQl3B.png

For reference this is my criterion. https://i.imgur.com/Ri9MlNG.png

That does not look good. The land/groove goes flat, and then there appears to be a high burr too.

It does not "go flat" it it the start of the rifling you are seeing. Right by the chamber. But the burr does concern me.

Gotcha. Hard to tell with the scope view the orientation. Normally the only burrs you can live with are from the port reaming. And with the nitride, that burr might be tough to shoot smooth. Can you see that with the naked eye looking into the bore??
