Bought new AK Opap, found this muzzle damage. Opinions wanted.

Well I was cleaning up the new OPAP I just received. Everything was going fine until I found what looked like a little booger of cosmoline just barely into the muzzle, maybe a few milimeters. So Im thinking that I'm getting it off with a q-tip but cant seem to get the whole thing. I ended up putting on the screw on muzzle cleaning protector and running a 7.62 brush through it with some hoppes......

Found out that the "cosmoline" must have actually have been rust, because what I have now are either two tiny scratches that were under the rust or pitting. Both marks, whatever they are are about 1-2mm and on either side of one of the rifling grooves. When I take a dry q-tip over them the q-tip doesn't snag its cotton on them at all.


I haven't shot this rifle yet but am concerned that this is going to ruin the accuracy. This is my replacement OPAP and I'm starting to get annoyed at my luck. The way I see it I have these options:

--Send it back (again, either to J&G--again, or just directly to century)
--See if a gunsmith can smooth it out
--Just Shoot the thing and see how good/bad the accuracy is
--I guess an extreme way to deal with it would be to have the barrel re cut, which I'm sure is expensive.

Would like some opinions here (attached an image on next post)
