Freeing up an sks bolt

[ThusEver2Tyrants]

Hey guys

I have a yugo sks that I bought un issued in cosmoline a few years back. Ive shot it a little bit but the past year it has sat in the safe so im considering selling it. Only problem is, the bolt seems to be seized up. What I mean by this is the firing pin is stuck in the out position, im guessing due to cosmoline still in the bolt? Odd bc it wasnt always stuck as ive fired it on a number of occasions and didnt get a slam fire. I want to remedy this issue before I sell it. Any ideas??? Ive tried to get the bolt apart by tapping the side peice out but it too is stuck I belirve from the cosmoline.

Soak it in gun cleaning solvent or mineral spirits paint thinner over night.

Soak. Then pound it with a hammer. The retaining pins are in there tight. You may want to throw it in a baggie and leave it in the freezer overnight, as well and the shrinkage might help you get one or both out. The pin and or the pin hole in the bolt face might be hosed though, recommend you look at Murray's spring-loaded kits.

PLEASE do no use this rifle until you free up that FP. Like rc said, soak in solvent until you can free it up enough to disassemble. Set the bolt on two 2"x4" with the bolt pin in the void between the tow boards. You'lll hafta whack it perty hard. Once the pin is out, disassembly is easy. Clean that bugger good, apply a LIGHT film of oil, reassemble.

And if you haven't already, get all that cosmo out of your gas tube.

Did you clean it the last time you shot corrosive ammo? Had a friend who didn't and his firing pin froze in "go" mode.

Mineral spirits for a few hours, wipe the bolt off and then drive out the FP retaining pin. Use brake cleaner to clean the FP channel and reassemble.

The firing pin channel needs to be completely free of grease or oil that can cause it to gum up like that in the extended postiion, where it can slam-fire a cartridge when the bolt goes forward. Use mineral spirits or some other grease solvent to clean it out completely before trying to fire it again, it's very dangerous in its current condition.
