i pressed out my barrel today and noticed that it was chewed up, it looks like it was from the barrel being pressed in, and not when i pressed it out, due to the way the metal is pushed, you can see it in the pics, any ways doesnt look like it will have any serious impact besides just being ugly. but what do you guys think?

Ewwwwww.... us in the tool & die industry call that galling. You've got it really, really bad. I've never built an AK and don't know enough to comment on weather or not it will hurt anything, but clean that up and lube it with some Lubriplate or something before you go to press it back in.

Chances are, it was pressed in by machine originally and there was a bur on the trunnion. You'd be amazed at the amount of damage a tiny little burr or shard of metal can do when it has no place to go.

If it was shooting good before you took it out, then smooth it and put it back.

It happened when you pressed it out. Use a belt sander to dress up the part that would be seen on the chamber side. It will be fine.

To help prevent that I started using anti-sieze once the pin is out and it's almost always not left a mark. I think it is usually from the sharp edge from when they drill the barrel pin. Just a td of A.S. on a q-tip in the hole and all is good. Be sure to use it when you install the barrel.

I'll give you 50$ bucks, tops.

I slept at home last night, not HI Express.
