I give up on this Chinese SKS that won't work!
A friend gave me his Chinese SKS to shoot and see if I wanted to buy it. I bought a rear sight for it and took the scope off. I cleaned the ENTIRE gun and put it back together and it is a SINGLE shot. The bolt only comes back about half way which is not enough to eject the spent cartridge and load another one. I took it apart an cleaned the gas port again just in case, but that has not helped.
I have the orginal fixed mag and I also have tried one of the removeable high capacity mags and that didn't help either.
I guess it must be either the piston or the spring not working properly.
Can anyone help me figure out what to do next to get this thing to work?
My friend has now said he is giving it to me since it doesn't work. I'm going to throw it away if I can't get this thing fixed.
Sounds like it is missing a piston or OP rod?
Other than that if it cycles smooth by hand, IDK?
Throw it my way if you want. :)
I'd definitely be looking at the gas cylinder, piston, spring area. Can you find someone else in your area with a similar rifle, to swap out some parts , and see what you find?
Don't throw it out!
FTR, I am not an expert and haven't slept at Holiday Inn in years.
Does it have the grenade launcher? The gas valve may be bad.
I'd suggest asking about your problem over here at The SKS Survivor's Boards
BTW, I read some where that it is a bad idea to even dangerous to swap out SKS parts.
Going to be very basic here as I don't know how familiar you are with the SKS.
First try some different ammo. Some of the Wolf has been know to be under loaded and may not cycle correctly. MOST LIKELY CAUSE.
Second, as the other guy said, cycle by hand for any hang ups you can feel. Do this with the recoil spring out also for a better feel.
Third, does this gun have a gas port selector on it? This would be a valve at the gas block. If there is a valve, make sure it is correctly positioned to pass the gas. Check the port on the valve for carbon build up. Even if it does not have a valve, pass a rod or punch through the gas hole to the barrel and make sure there is no carbon build up.
Forth is to check that the gas piston is correctly positioned. Disassemble the gas tube and piston. The piston length should be flush (with a just a little play) at both ends between the gas block and secondary piston at the rear block.
Next is to check the block op rod. Use the gas piston or a punch to operate the spring loaded op rod in the rear block. Should have tension but operate freely. You can remove it and clean it by rotating the capture block arm all the way forward. Put your hand over it or it will hit the far wall being spring loaded.
That is the most likely stuff I can think of right now. Hope you can work it out.
Make sure the gas piston isn't bent and moves freely in the tube.
Make sure the operating rod isn't frozen or missing the spring. If that doesn't solve the problem run a gas port reamer through the gas port.
There's a reason the Chinese made those tools...
Hunter2003, your carbine is not supplying sufficient gas to operate.
Follow PolyPam's receipe above.
I suspect a previous owner shot some corrosive-primed ammo thru the rifle and failed to clean up effectively afterwards.
You should be able to ream out the gas port and get that axe working again. Keep it at, comrade.
My suggestion is to check the OP rod and make sure it moves like the previous person said. Take it out and make sure it isn't full of cosmoline. The other place to check is the recoil spring. I have sold many of SKS rifles and when they came back because they didn't work it was because the owner took the rifle apart and didn't put the recoil spring in correctly. Just make sure the curly/wavy part of the spring is inserted into the bolt carrier. If it is not in correctly you will have a single shot rifle.
Let us know what it is.
I have found a few problems with sks rifles not cycling over the years.
1: Remove the piston and spring that is under the rear sight and clean it if it has dried up cosmoline or thick grease on it on it.
2: Check the chamber for corrosion/pitting and if it does polish it
3: Check to see if the recoil spring is in Backwards
Yugo sks does not have a chrome lined bore and chamber and surplus rifles that look like they have been used a lot have corrosion from corrosive ammunition, I have had 2 polish the chambers on 2 of them to get them to cycle, once I did they worked as good as the other ones I have
I have also shortened a yugo to 16 inches, but you will need to drill the gas hole out larger to cycle the action as the gas dumps out to quick at 16 inches, drilling it out solves the problem, It works great now
