SKS Firing Problem - The Firearms Forum

TXHILLBILLY85 · 05-21-2011, 11:41 AM

I have a Norinco SKS I have been having issues with the rifle firing every other shell. I cock it back to fire it and it shoots but after I shoot the 1st round I go to fire again and it clicks. So I take out the magazine eject out the shell that is in the chamber put the magazine back in, cock it back and it shoots. So when I manually cock it it fires but when it automatically goes back it just clicks and puts a small dent on the primer. Im guessing its a firing pin problem but not sure. Please somebody help me Im confused. Because It was working fine.

Strip the bolt assembly and get after it with a can of carb cleaner. Do the recoil spring area also.
Check here for info; also Murray makes a replacement firing pin that can't be beat and removes any danger of slam-fire:

Also, pull the gas piston and check for hardened oil build up in the gas cylinder. If the piston hangs up, it may not be cocking the hammer all the way back (which you do by hand).
There may be some crap built around the hammer pivot, also. One of the most common problems encountered with SKSs is improper removal of all the caked on preservative that they soaked the guns in before shipping to the US.

Welcome to the forum.

My guess? Crud in the gas system somewhere, which is causing the gun to
short stroke.

The old original SKS tool kit had a gas port reamer in it---for a reason.

Its caked with cosmo. Strip it and put everything you can into a pot of boiling soapy water. The trigger group and bolt especially. The firing pin is cushioned in a sleeve of cosmo within its hollow in the bolt and its slowing the firing pin down and causing light strikes. Carb cleaner and hot boiling water are just about the only ways to get that crap out...

I prefer to boil them, and then set them out of the pot on a dry towel, they will dry very quickly because they will be very hot. Then just soak em with gun oil.
