Hey guys..
I'm noticing on one of my SKS's (a number matching, mint condition, 1952 Tula) that when I finish the clip, the spring and rod thats inside the front leaf sight there remains stuck out. If you rack the action hard it will lock forward normally and push it back in...

It has affected cycling while firing a few times, as the bolt doesnt always hit forward fully...

It almost seems like it gets stuck there, as if it were forced back too hard (from too much gas pressure) or something?

I don't remember it doing this before.. so I was wondering if maybe I need to oil it a bit more, or if its a known issue...

All I've done to the rifle is put it in an aftermarket stock and add a tactical rail (wartek).. havent touched the rest...
 
Take it right out, clean and lightly oil. You can also inspect it for a bend or burr at the same time. Likely just crudded up.
 
close inspection shows no damage to the perfect black paint/bluing on the piston rod or the other little rod, and the spring looks mint as well.

Also super clean, but i wiped it down with hoppes elite, dried it, and applied light oil just to be safe.

will report back after firing
 
I had a similar problem;
The answer in my case was to replace the piston return spring that is around the piston extension.
It wasn't perfectly cylindrical, and was binding on the extension, and inside the housing.

Also be sure the piston extension is very smooth, and the spring compresses without any resistance.
 
It is true the SKS's manufacturers were not big on springs, that's why you see the ones that look like braids or all twisted together.
 
where can i get replacement parts? i'm not seeing any on hical or westrifle..
*update* nevermind, found everything on lever arms.
Just sucks that they dont accept online payment, you have to call in your credit card.


Anyways I hope thats it.
 
i have/had the same issue,, stripped and totally cleaned the piston and tube.. have not fired it yet.. but
strange it just started happening ..
thanks for the info...
 
Is it possible that old grease has glazed the inside the tube on the rear sight assembly? You could try putting an appropriately sized brass bore brush on an old section of cleaning rod if you have one. Chuck it up in your drill, and dip it in barbeque starter, kerosene, or some such thing, insert, and whirl away. Do it from both ends, because a sticky patina on the walls where the spring is might catch it while the spring is compressed, and thus slightly bigger in diameter.
