Need help on my 10 22 takedown. Please advise

[steelfingers]

Below are two pictures. I noticed yesterday, I had a couple of stove pipes that I blamed on the ammo and the federal ammo.
I broke it down and was looking in the receiver and found this spot. It's rough and I think I need to address it. Its at the top of the pictures center. You can see the shiny wear and its barbed and rough.
Wanted input before I take a dremel to it to smooth it out.
Opinions PLEASE!
I've seen YT vids on things like this but not exactly this.

You talking about here? I'll get my takedown and compare.

I've noticed the "newer" 10/22s can use a good "polish" on the inside of the receivers...I've done it to each of mine.

Yes. Should I dremel that smooth. It's burred and rough. I need your suggestion on how much to take off. I'll screw this up on my own.

Mine looks worse than that in the same area...so I dont think thats your issue. I polished the flat surfaces in the rest but appear to have not done this one yet.

Those receivers will respond very well to a good file set and some 400-1000 grit oiled paper.
