I have a Romanian WASR and am trying to disassemble the bolt in order to clean it and check the components for wear. The punch in the cleaning kit is too large to fit in the hole for the firing pin retaining pin. Wat do?

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.

For future reference, WD40 kinda sucks at everything. If you want to bust some rust check out penetrating oils like Liquid Wrench, PB Blaster, and Kroil.

I'd probably spray the parts down with penetrating oil and then wrap it in a rag and let it sit for a day or two. Even better if you can submerse the parts.
