I got a pretty nice Romainian SKS w/(short)scope. I shot it a little bit today (30 rounds) and still didn't get the scope completly sighted in yet. but I did notice it has a problem. I don't think its ejecting the spent cases correctly, when I fire it it catches the spent case in the bolt and or bolt carrier. I don't know why, I'm thinking maybe the case is bounceing off the scope but i don't know it is a short scope, going back twords the action and geeting caught by the bolt a/o bolt carrier. so I have only been shooting it single shot because it keeps jamming like that (even with only shooting it single shot)(although I was able to shoot 2 or 3 shots in a row once, and it caught the 3rd case in the bolt). does anyone have an idea why it is doing this? I really would like to shoot a whole 10 round mag out of this thing (continuaously, not haveing to un-jam the spent case after each shot)
whats up with my SKS?

no maybe i should try that but i almost have it sighted in i dont really wanna take it off but that would confirm if its the scope thats causing the problem.

GunGeek,
I would think you have fired enough rounds that, if the casings were hitting the scope, there would be some evidence/marks on the scope to indicate that.
I would think that if your situation was the result of premature recycling and closing of the bolt before the spent cartridge had been fully ejected the bolt would also pick up a new round and thereby cause a jam. But, you didn't mention that.
Although, it is possible for premature recycling to begin again before the bolt is far enough back to catch the next round. But that is a fairly rare occurence.
It almost sounds like the bolt isn't traveling far enough back to give time and clearance to make a clean ejection.
Have you checked the gas tube and rod for free movement or problems?

Possible problems:
The gas system isn't clean. They can gunk up quickly. Check the gas port in the barrel, too.
The recoil spring might have been installed backwards, causing binding.
The ejector may be worn/faulty. Most Romanian SKS's down here are very well worn.

when i would load the mag wit more than 1 shot it normaly would pick up a new round but it would still catch the spent case so i only loaded 1 shot into the mag at a time, ill look at the scope but i dont kanow if it will be niked i have flip up scpe coves on it. thanx for all the help and sugestions guys
Regarding the recoil spring-
Make sure the Spring Retaining Cap is facing forward(it's the "cap"that holds the recoil spring together with the spring guide.
But, also check the Little Piston and the accompanying Spring. This is being held in place by the gas tube takedown latch on the gas block(the little piston is inside the gas block). It's possible that the little spring is weak or broken. Use a finger to hold the piston in place(it's under spring tension), and then swing the takedown latch all the way up, counterclockwise. Clean the interior and the sping and piston.

I got to examine GunGeek's SKS and I think I may know the problem. The piston seems to be pretty loose in the tube, with more clearance around the outside than my Norinco, which is pretty tight. I think the gasses may be going around the piston more than they should, and not applying the full impulse necessary to cycle the action.
Does it sound like a good idea to try my Norinco gas system on it to see if it fixes it? If so, Gungeek could get a new tube and/or piston, such as Tapco's American made combo.
