What are some of the likely causes of a Chinese SKS to stove pipe? Thank you.

Never.  Although I have only shot mine about a 1000 times, a friend regularly abused them and never had a Stove pipe.  He didn't see the need in cleaning them.

I am curious as to why you ask this question.  Did yours stovepipe?  The bottleneck design of the cartridge should limit this.  Do you use the 10 round original magazine or an aftermarket 30 rounder?

Do you clean the gas system well?  If it gets dirty enough, it may cause short-cycling.  Also, check the recoil spring - kinky end forwards!   8)

If its stove piping it maybe short cycling I would clean and lube the gas tube and clean the gas port to the barrel.  I would also check for old cosmoline since some of the used chinese sks's I've purchased still had cosmoline in them.  I've even bought brand new looking sks's with stuck gas pistons from the cosmoline not being all cleaned out it melted and glued the gas piston.  I like to put a little moly on the gas piston as well inside the reciever on the bolt carrier and bolt too it will keep your sks tickin.                                                                 BigBill

I'm going to add the wear factor in too. Since most of these guns were abused and the gas systems were run dry I'm wondering now what wears first the gas tube or the piston since some of them aren't chromed(yugo). I would check the play of the piston inside the bore too.  I did replace a piston in one of my used albanian sks's because it felt really loose in the tube.  Most of my chinese and russian sks's are unissued so their tight fitting yet and their chromed too(piston).

Sometimes one of the aftermarket add-on recoil buffers can cause this.If you have one installed,remove it and see if your problem goes away.

The only stovepipes I have ever had with an sks were due to shooting reduced loads. If your ammo is OK looking at the gas system as stated above is probably a good idea. Give the gun a good cleaning.

Check the area where the tube of your gas system attaches near the front gas ports on the top of the barrel.  Sometimes the gas piston tube can have a very small gap in it allowing some gasses to escape before the piston has a chance to stroke the bolt back.  Check for power residue.  I know several folks who have had this problem with Yugo SKS's (myself included). A buddy of mine took a small circle of brass (from a 45 ACP case), annealed it and lined the inside of the gas piston tube where it connects to the front gas port.  This created a tighter seal and his misfeeds stopped.

The front of the gas tube gets egg shaped from raising it too high when you remove it from the gun.  It actually prys the bore egg shaped in the process.  Its better to keep the gas tube as close to the rear site as possible to remove it from the gun.  This is why the bore opens up and gets loose.  I haven't tried it yet but i think it can be peined back to the orginal size very carefully.   I have heard of some putting "o" rings on the front too to seal the gas again too but its a temporary fix to see if thats the problem.                                                        BigBill
