Need help with SKS gas tube/piston

Took my SKS apart last night to clean and took the gas piston out of the gas tube. Didn't pay a lot of attetion at the time, but after I cleaned it and the tube, then oiled it up, it seemed like it went in harder.The head of the piston drops in flush with the tube, but when I take a smaller rod and push on the head to simulate the normal movement during cycling, it's not smooth. Kind of like there's one spot hanging it up or the tube isn't completely round. I don't have to push very hard but a little none the less. When I actually fire the weapon its going to have a lot more force so it's certainly not going to be a problem. But should this be a concern?Thanks,GL

    Not too sure about your piston problem, but I read or was told some time ago not to oil the piston or gas tube. Should be cleaned and replaced dry. So thats how Iv'e done it. Maybe someone can confirm this.

    According to the two manuals I have it says to 'lightly oil'.Like I mentioned, I wasn't paying too much attention when I took it out so it may have been a little tight to begin with. I've since taken the pistol out of one of my other sks's and tried it for fit and that one fit like a glove. So I'm beginning to think it's just the way this piston happens to fit in my rifle.

    Usually there isn't a lot of play in the piston and the tube. As for oiling, I wouldn't. I have no idea what the manual says, all I know is what I've learned from dealing with SKS's for the last 15 years. I've taken several hundred SKS's apart, I've never oiled the piston. It is however a good idea to run a brush through the tube. It removes some of the fouling left from shooting. I usually use a bigger one for the front and a smaller one for the rear. Again it isn't uncommon for the piston to ride in the tube with some stiffness. To get a good seal, there can't be a whole lot of play room in there. The best way is to reassemble the gun and try shootin it. If everything works the way its supposed to, it isn't a problem.
