Cleaning SKS bolt

Although I have yet to have any slamfires, I noticed that my SKS' firing seemed a bit sticky inside the bolt. After removing the bolt from the gun I'd turn it over and the back. About nine times out of ten gravity would move the firing pin, but that other one time it'd stay where it was previously.

Unfortunately, I don't have many tools so I went out and bought a 1/8" punch today -- this is just the right size for those of you who are curious, even slightly larger would be too big, one could make do with a smaller punch though. I was expecting to see large amount of gunk on the parts of the firing pin that were covered by the bolt, but when I opened it up everything looked pretty clean. Nevertheless, I took the four separate parts and soaked them in hot water for about ten minutes. Then I thoroughly dried them and put a bit of Outers gun oil on the inside of the bolt such that it would lubricate the firing pin. Now that I've put everything back together I'm not really sure if the firing pin is more movable now or if it was better before. What do you guys do to prevent slamfires? Should I have done anything differently?
 
Check out 3w.murrysguns.com who have improved firing pins & return spring kits to eliminate slam fires, and they ship to Canada. I replaced mine a few years ago and have had no problems.
 
that and when the bolt is slammed back there is a bit more than just the force of gravity pushing the pin back ;)

Yes, that bit more is called Inertia and due to the mass of the firing pin it may put a deep dimple on commercial ammunition primers that may result in slamfire when the bolt returns to battery.
If one has the means, a replacement firing pin machined from Titanium is a fix as the specific gravity of Ti is much less than steel resulting in a reduced mass of the pin.

Or just trade your SKS in for a 1950 SKS like mine, and it should have a spring loaded firing pin already. :p:D:D

BTW, I think what you did was perfect. Now you know its squeaky clean.
 
I just oil the pin every time I clean the Rifle. I only take it apart about once or twice a year when it needs it.

I don't think your supposed to oil the pin. I was always under the impression that you wanted the pin totaly dry so it did not get gummed up with powder residue.
