Sks fte

[rifleman1377]

So my sks has been having some FTE recently. All of them are stove pipes. Any ideas on how to fix it?

Is it a Yugo? Check the fittings on the gas tube. Most likely a leak. Weak ammo can also cause a poor push on the gas tube. My bet is on the valve itself. Are you using a recoil buffer? Those can cause nightmares as well as they limit travel.

Make sure the chamber is clean. Surplus ammo or the non corrosive ammo like the Barnaul stuff has the shellac on it which can be deposited in the chamber after a while making it sticky and harder to eject. But as asked, not knowing which make of SKS you have it could help us narrow it down some more.

 

[rifleman1377]

No its just a 1956 russian SKS with no modification. I have been only using copper washed Chinese/Romanian.

Gas port is clear?

 

[6MT]

Have you cleaned the gas port and piston? If there's wear in the tube, you'll get escaping gas that won't drive that piston back hard enough.

Check that your extractor claw is clean and sharp. It may be that the empty shell isn't being gripped well enough to fling it clear before the bolt closes.

Look at how your mag is pinned. I had to use a dremel on a few mags that were poorly pinned.

FTE on an sks!? Mine flings them 25 feet!

Check your gas system, especially the gas block (where gas goes from the barrel up to the piston) and make sure everything is nice and clean. Do not oil the piston either.

I am hearing alot of recommendations on the piston and that is a area I am not too sure about

Here are some pictures




Also the extractor is fine and the mag is well pinned.

The critical areas are the OD of the piston and ID of the tube. Too loose and you get too much blowby to properly drive the piston. I don't know if the specs are out there and its not an eyeball procedure to diagnose. On another note, is the squiggly end of the recoil spring assembly inserted into the bolt carrier? Installing it backwards can cause cycling issues with the SKS. If the spring is installed correctly then I would try a different gas tube and piston.

My sks will eject the round just fine, but it won't feed the next one properly and crush the casing of the new round, with the bullet pointed up and out of the chamber

Something amiss with the mag, is it pinned internally, if so is the follower able to swivel easily, some pinning jobs have caused the follower to be stiff or not swivel at all and that may cause you improper feeding!

My buddy is having the same problem. I think it's a magazine issue, but i haven't been able to take a good look at it yet... every 10-20 shots a round fails to chamber, with the exact same results...

One of my SKS does this ^^ as well, there does not seem to be any detectable reason but every 10-20 shots, it stovepipes a live round.
It has the pin on the follower but I have others pinned in exactly the same way with same freeness of movement without the Fail to Feed.

Possible gummed up chamber, from lacquered ammo or old Cosmo! Clean the chamber really well !

probably follower doesn't go freely all the way or magazine bent.
