SKS Problem

gnprts
I purchased a 20 round fixed magazine for the Russian SKS and I had lots of trouble with feeding. After looking the magazine over I found the pin was loose and repeended it and it cycled ok. I took it to the range today and I had some stove pipes and some double feeds. Anyone got any ideas were I may adjust this magazine to take care of this problem.

I was using the old steel core ammo and a friend gave some new wolf ammo to try in the rifle same result, one or two jams or double feed per twenty rounds. The rifle had only about 50 round through it prior to this firing.

Thank, you

    Have a Yugo SKS that won't cycle. At first it was firing a shot and then stovepiping. I cleaned it real good and now it just fires one shot at a time, no noticeable bolt movement at all.

    I believe the gas valve is in the correct position (down) as this allows the gas into the gas tube, thereby causing the action to cycle. I admit I didn't try it with the valve in the up position, but it appears that would block the gas escape hole. I cleaned it well before firing it.

    Also, it's very difficult pulling the bolt back by hand after firing.

    ..might not want to proclaim to the world too loudly about this, a better way to put it would be IN THEORY what may make an sks go full auto.[;)]

    as to the question im not sure but i would think the sear would have taken care of it. since you changed the firing pin..slamfire maybe??
    did it start after the firing pin was changed?

    There have been issues with replacement SKS firing pins being a bit too long and causing the problem you described. If the rifle was imported by Century Arms there have been reports of some rifles with bad trigger groups but if the problem started when you switched firing pins I'd say that is where you problem is.

    The problem was there before changing the firing pin which was changed because of previous issues (slam fires) with the SKS rifles. I thought the sear would possibly clear it up although the exchange shows that it is not be the problem. This appears to be a disconnector trigger group problem.

    If the rifle was imported by Century Arms then the problem is known and they should be contacted to arrange for you to return the rifle. If it is not a Century Arms SKS then you most likely still have a trigger group problem but you'll be paying for the replacement parts yourself.

    I edited your original post so that it no longer mentions your actual problem, since that is not something that needs to be seen floating around on the net long after this thread is finished and locked.

    gnprts it sounds like a disconnector problem. If random occurance, mil spec CCI small rifle primers would solve the problem.

    Mark .... Thanks for the edit. I did a Google search and found some ideas that may work. One clue worth noting is that the hammer is in the fired position when the last round has been fired which I suspected.

    guprts sure sounds like the disconnector is not doing its job. Are you sure the disconnector isn't broken or "modified"?

    5mmgunguy.... The disconnector does not appear to have been modified and is not broken. It is doing its job by catching the hammer when the trigger is pulled with the trigger group out of the rifle. I became involved with this problem after the firing pin change did not work for the owner. I am inclined to think the sear is not holding the hammer in the cocked position. If this is true the disconnector is holding the hammer until the closing bolt trips the disconnector.
    Thanks again...

    So the hammer will not stay in the cocked position ever?

    To make this more difficult I only have the trigger group but plan to get the complete rifle today. Since I had two trigger groups I decided not to keep the rest of the rifle...( my mistake) by comparing the two triggers and having them both working alike on the bench should have cleared the problem up... Not in this case! Yes the hammer will stay in the cocked position. All parts appear to be near new.... [?]
