Well, this was fun.
>determined that the proper size for this specific bolt is 1.7mm or 1/16"
>went to Harbor Freight
>got punches
>repurposed roll of electrical tape as machinist's block
>broke two steel punches while beating on them with a three pound dead blow mallet
>soaked bolt in WD40 for 72 hours
>tried again
>this time just bent two steel punches
Found rust inside the firing pin channel inside the bolt, and severe rust/corrosion in the extractor recess, as well as in the spring slot inside the extractor itself, which was clogged with rust. Extractor spring was caked with rust. Lacking spares, I scrubbed all the rust out, cleaned them, gave all parts a very light coat of oil, and reassembled the bolt. It went back together a lot easier than it came apart and may eventually wear in to the point where it comes apart and back together with finger pressure if I do this a few hundred times. I am astounded that the rifle ran at all in this condition, and am disappoint but not surprised to find a more or less new rifle like this.
I think part of the problem is that the bolt and components were given a hot caustic dip blue finish rather than something more corrosion-resistant, and the corrosion I found was in places where bluing salts could have been left behind after finishing, if they had not been rinsed properly. I expected Cugir to have their shit together, but maybe not. At least it runs.
