has anyone ever removed the gas plug and how do you do it? i put my gas tube back on but used the wrong piston and now i can't budge it to remove. i have tried prying it up but it won't move so the only option i can see is to remove the gas plug. i see there is a pin holding it in place but what i don't know is how to take it off after that. do you know a gunsmith near Winnipeg that could do it if i need one?

Oil it then smack the small opening end on a board to get it moving, then the big end. Get it moving and it'll come out.
Or use a punch down the small end

It is possible that you don't have the gas tube removal lever in the correct position, the stickies can provide photos. Or it is possible that it is jammed
in there because of rust, in which case check that the operating rod is not sticking out into the reciever as if it were pushing on the bolt carrier. If it is,
push it back into the hole and that should allow the gas piston rod to lift clear. Or it is possible that the gas tube removal lever and catch are rusted
and preventing the tube to slide up and out. I would not try to remove the gas block or plug as you called it, that is a whole lot of risky work.

this rifle has not been shot. there is no rust anywhere. i have turned the the gas tube removal lever all the way and i still can't get the tube out. the only solution i can see is to pop the gas block pin and slide the gas block towards the muzzle. the only thing i don't know is if the block is a press fit or just tight.
 
I'm still not understanding the issue. OP, are you referring to the long gas piston or the short one?

If the gas tube can come off the rifle, then a small dowel should be enough to tap the long piston loose. If it's the short gas piston, then it's likely you don't have the gas piston lever in the right position. When disassembling the rifle, that lever turns a block which is the only thing holding that short piston in place. Be careful when you turn the lever as that piston can come flying out with spring pressure. If the lever is in the proper position and the short piston is stuck, it may be due to cosmoline holding the piston in place. If that's the case, take a small dowel and tap the piston out from the breech side. Again, be careful as the piston may come flying out under spring pressure - folding a small shop towel over the muzzle side of the block should catch the piston if it does come flying out.

The Russians were, shall we say, overly generous with cosmoline when they put those rifles into storage......

edit: after re-reading your last post, you may be turning the gas piston lever too far. Try turning it until the gas piston lever is at the first detent - that should be about 45 degrees from flat on the top. That will make the block vertical, which is how you have to get the gas tube off the rifle.
 
If the upper handguard is still on the rifle you need to flip the lever at the rear sight up to the first notch, you'll feel it click into the dimple. That will allow the handguard and piston inside the handguard to be removed, you might need to pry gently with a flathead screwdriver if it's tightly between the gas port and rear sight block.

Once it's out you flip the gas block lever further forward to release the small piston and spring from inside the rear sight block, it will shoot out if you don't hold a finger over it while flipping the lever forward. It's very simple if you haven't already done this. Big gas piston should come out of the handguard tube with a smack or just slide out.
 
i have 2 sks's and i had them both apart. one 1951r and the other is 1952r. without thinking i reversed the gas tubes but used the right piston. i know how to remove the gas tube as i have done it countless times. but this time i can't even get it to budge. the only way i can see to remove it is to push out the pin on the gas plug (block) and then move it towards the muzzle.that is the part you first push the gas tube in then lower the backend by the rear sight.
 
If your in Winnipeg and want to meet up I could try to help you. I have worked on many. Sounds to me like a combination of finding the sweet spot with the lever and gently prying up on the hand gaurd. Some are a very tight fit. There are things to try before resorting to remove the gas port.
 
if it went in without a hammer, it'll come out without a hammer. As above, keep moving the lever, sometimes it has to go a lot farther than you think it should.
 
one thing to look at is maybe the second pin is forward because the piston stuck so take your bolt carrier apart and gently tap the secondary charging rod, the one that goes under the sights make sure it is as far back as it goes with the spring tension and this will ensure your piston is as far back as it can go as it may be hanging up in there do you know what i mean?
 
problem solved. boy do i feel stupid. i have never done this before. i didn't realize i forgot to put in the piston and spring so the gas piston went into that hole and blocked me from removing the gas tube. thank you all for your help and offers to meet me to try and correct the problem. once again thank you.

It was fun for us and it benefits everyone because we avoid making the same mistakes. Unless you are getting up there like me and you forget things.:wave:
