SKS Mystery Spring - Where Does it Go?

General Firearms Other Semi-Automatic Rifles

I was stripping down my Dad’s new-to-him Russian SKS [don’t ask, must be nostalgia] in order to clean it, and in the middle of the prosses I notice the sping [attached at bottom of post] laying on the counter. It did not shoot out of anything, I did not even hear it drop out. Just appeared there.

I looked through the dissasembly manual I printed off the internet, never pictured. Looked online at countless exploded diagrams, can’t find it. Hopefully one of you guys can help me out.

I finished cleaning the rifle and put it back together. Eeverything went back just fine.

Functionality check went fine too. Pull the trigger - click. Cycle the action, pull the trigger - click. Put an spend/empty 7.62x39 case in, close the bolt, pressed the trigger - click. Pulled the bolt handle, casing goes flying hald way across the room, bolt locks back on empty mag.

I have no idea where it came from. Asked my Dad, but the last time he field stripped an SKS was in the mid 70’s when he was in basic training for the Soviet Airforce lol, so he has no idea either.

HELP!

Sorry for the poos quality of the pic, it was taken with my old a$$ iPhone. I put a quarter in there to show scale.

:smiley: Thanks guys!

Firing pin spring?

I think only Chinese and Russian rifles had them.

I was thinking the same thing… but I saw no are where a spring can be inserted into the bolt with the firing pin… The firing pin looks like its detained by a tapered pin through the bolt, I did not remove that pin.

I was also thinking the magazine release spring [this is the SKS type that loads with a stripper clip from above not with a detchable magazine] but the mad release moves normaly locking and unlocking the box below the action.

Im going to have to take it apart again and seach every opening for where thing thing may possibly go…

Figured it out!

Yay me!

The spring goes inside the extractor and holds it tight to the bolt!

Yay!

Funny how the extractor still worked without the spring… freakin’ odd
