SKS slam-fire / full-auto fix?

[twitcher]

Anybody have any experience with the SKS replacement firing pin / spring from Murray's that supposedly eliminates slam-fire and full-auto incidents?

Had both happen at the range today, so wondering if this would be a worthwhile investment. Or any other suggestions?
As an aside, I was shooting Wolf and Sellier & Bellot ammo, and both slam-fire and full-auto happened with S&B... But maybe that was just a coincidence.

Thanks!

The early russian SKS had a spring like this one from the factory. I've had several Yugo and Chinese SKSs over the years, but have never had this problem.

The modification is probably worthwhile, but I would first do a very good cleaning and check for burrs or something on the firing pin or firing pin hole on the bolt face causing the firing pin to get stuck.

You most likely either have a dirty firing pin and channel or a damaged firing pin. Take it apart and clean it very well, get all cosmo you can off of it and do NOT oil it upon reassembly!

Now... I got one of those pins and dropped it into my Yugo and it works fine.

I have never had this happen to me, but here are the things you can do:
1) Try shooting milsurp or Wolf ammo. The point is to use ammo with harder mil-spec primers. Some of the US made commercial grade ammo has softer primers.
2) Disassemble the bolt and check the firing pin. Clean all the crud out of it. On some of the SKS', it's nearly impossible to remove the firing pin from the assembly, but you can spray the cleaner into it and remove anything that may clog it. When you are done, the firing pin should shake inside the assembly easily.
Next time you are at the range, load just two rounds, test it, and if that's ok, try three and so on.
You could go with Murray's spring loaded pin, but if there isn't any damage - it's not necessary.

BTW, following the recent federal conviction of an individual with a malfunctioning AR, you should probably avoid lending the SKS until the problem is 100% fixed.

If you can't get the bolt disassembled to clean the pin gallery douche it out with automotive brake cleaner(wear safety glasses in case the spray goes wild) don't oil the pin after just spray it out really good.
As stated the pin should float free in the bolt.

I wouldn't worry much about a conviction. The guy with the AR in that story tampered with it heavily.
There's more to the story like the selector rotating all the way to the auto range, the M-16 hammer.....
The malfunctions were from messing where he hadn't oughta been.

Get the Murrays setup.

3 yugo's, I never had a problem with slam firing.
Have used wolf military classic --> BTW, these are awesome ammos, way cleaner than the black box wolf.
Also, thorough removal of cosmo. Fieldstrip your SKS and dis-assemble the bolt then clean the firing pin and the firing pin hole thoroughly. Spray some CLP and use a q-tip or something similar to remove all the gunk in there.
I've also found WD40 to be very effective on removing cosmo.

I got just the spring from Murray's and installed it in my type 56. Works like a charm and no slams since.
