Issue with Murrays Firing PIn - SKS !! Anyone else had this happen?

Why is it that the SKS's seem to get the most paranoia about the free floating firing pin? Is it just a lack of proper cleaning and maintenance that created a faux slam fire problem that got out of control? I rarely hear of people worrying about free floating in other similar rifles.

I thinks its due to surplus ammo causeing rust really fast and people don't clean things because they're so cheap. It can also rust in the closed position so rust by it self might not do it has to be out when it gets stuck if it gets stuck in it just won't fire at all.
 
Its unreal how worked up people get. Considering to properly clean it only adds another maybe 10-15 minutes. I pull my gun apart, and throw all the parts in a pot that is on the stove warming the water to run through the bore. Once it starts boiling I pull out the bolt, carrier, piston, op rod and spring and set them on a shop rag. They are dry in about a minute cause they are hot from the water. Take the receiver/ barrel and dump water down the bore through the gas system, and run the brush through it followed by a few patches. While that is drying, I pound out the retaining pin on the bolt and clean out the bolt, and clean the firing pin and re assemble. Now clean the gun as if you were not shooting corrosive. Total extra time about 10 minutes....If you clean your c=guns properly =, you will NEVER have an issue. I take the bolt apart every time and make sure its clean, it only takes a couple minutes more, and I am ensured that I will have trouble free operation when I go shooting..... SIMPLE. Ditch the Murray's pin and keep your gun clean. No Problem!!
 
Murrays firing pins are designed for people shooting non-corrosive, modern, non surplus ammo. It lets you put a quick spray of G96
on the firing pin and it won't rust or gum up, and is safer with the spring. It's not designed for the hard dirty surplus primers.
 
If you want to get the most ammo flexibility out of your SKS, you need two separate fire system sets. Keep the original bolt and trigger group unmodified for surplus or berdan primed ammo. Then acquire another bolt/carrier and trigger group modified with a Murry's firing pin and lighter hammer spring for the boxer primed ammo. Getting the proper head space will be an issue so you will have to buy a few stripped bolts to be sure. A tuned recoil spring wouldn't hurt either.

Yeah, it looks to be allot of work, but this way you can get the most out of your SKS. I would a agree that most accuracy/reliability issues with the SKS are attributed to improper care and maintenance. It is a great gun, I see no problem spending money on a "cheap" gun.

I agree completely! I worked on the trigger until it's smooth and light, polished everything, changed springs, and put in a Murray's pin.
I only shoot Boxer primed non-corrosive and the rifle is great to shoot...albeit more expensive than if I were shooting the dirty surplus stuff.
If I have the burning need to fire off a ton of rounds in one day I'll bring my 10/22...lol...
