Help with SKS

[rk3006]

I have a Norinco SKS that I'm having a problem with and I need help. After a range session last fall I was taking my SKS apart to clean it and not paying attention to what I was doing, when I went to take the gas piston off I raised the take down lever too high and released the small piston under the sight and now the whole gas tube is locked up because the small piston went forward and there is no way to raise the gas tube. I tried to punch the pin out holding the front gas housing to move it forward but the pin is frozen. Anyone have any ideas?

P.S. They have some great SKS parts, also.

I'm not in the shop just now but wonder that the gas piston extension was small enough to move forward enough to enter the gas xylinder assembly. It should have had a head that precludes that from happening..? Is the rar tail of the gas piston extension visible at the rear where it exits the housing to impact the carrier assembly? The small end should be roughly flush where it exits.

I remember having to make a note in the disassembly book I have about that small spring loaded piston in my Chinese SKS's.  It was totally overlooked!  Sorry, but I'm not in a position to check out your problem right now.

Thanks Guys for all your help. I feel so stupid, I finally fixed my SKS but the problem was not what I thought it was. When I striped my SKS last fall I inadvertently forgot to put back the small piston and spring that I accidently released, When I fired the rifle the main piston got stuck in the space the small piston should have occupied. I used the cleaning rod from my SKS to push it back into the tube and was able to raise the piston housing. The only thind is I can't find the small piston and spring. I have a stripped Yugo for parts and it had the small piston and spring, I don't know if there is any difference between the Yugo and Chinease but it fit so I hope it works? Thanks again for the help, rk3006

Fit around the diameter is not too important as this is not a gas retaining part just an energy transfer device. The length is the important measurement. If the extension is flush at the rear with the takedown lever in it's retension position it should work just fine.
