That is the upside to the Norinco/Chinese SKS's; they haven't been used in battle for the most part, less worn.

Honestly, if my firearm failed due to a nasty firing pin, i wouldn't even admit it to my cat.

Russian, designed as the first assault rifle chambered in the new soviet M1945 ammo now more commonly known an the 7.62x39. It was based off of the SVT40 but was simplified and smaller. It was used for two years post WWII until the AK47 was introduced and finished its testing. It was then relegated to reserve duty until around 1974 when the AK74 came into service. However before that it was produced under liscense by nearly all Soviet bloc countries. It was used as a primary infantry rifle until the AK47 variants were either shipped in or manufactured. Again it was relegated to reserve duty until the early 90s when the cold war finally wound down.

Never Forget.

I asked about the nationality of the SKS's that malfunctioned, not the design as a whole. Mine was made in China; i'm betting the faulty ones were battle-worn units from Yugoslavia (I think Russia is a bit East of there ).

The Ruskies used springs in their F/Pins from 1949 -early 1951. You may not have a spring. Reason is i had a 1951 Tula and it did not have a spring.

Strange, I was under the impression an SKS was a scaled down PTRS41

anti-tank gun which Simonov designed, because we all know

an SVT40 is a Tokarev designed weapon with a box mag...

So three people you know and trust ALL had worn SKS firing pins,

yet none of us ever experienced it, after thousands of rounds through

all of our used SKS relics. OKAY...

^^^ Could've been a bad batch in that area?

Here is another angle on the "issue"...The SKS's in the US were commonly preserved with cosmoline prior to being shipped here. Cosmoline is a preservative, not a lubricant. If the internals are not cleaned thoroughly prior to use, the cosmoline will bake in and harden. Hardened/gummed up cosmoline in the bolt of an SKS can cause the firing pin to stick. A stuck firing pin can and does cause a condition called a "slam fire" This can cause the newly chambered round to fire as the bolt locks up. In extreme circumstances the gun can go full auto.

The other problem is that the firing pins are crudely machined with rough edges and burrs. This can cause a similar condition. My Norinco was rough when I got it. I removed the firing pin and deburred it. I polished the surfaces with crocus cloth so it moved freely. I shoot mainly domestic ammo and reloads with domestic primers (CCI and Winchester). I have NEVER had a slam fire.
