Looking for a replacement piston for the Gas Valve

The skinny part of the shaft appears straight and I've clean the piston and the chamber, but it still wants to stick.
The head of the piston with the threads appears to have some scuffs, so this is what I suspect is causing the problems.

Contacted CNC Warrior, but he's not sure his Yugo replacement would work.

I think buymilsurp.com has what you are looking for.

Get with me tomorrow afternoon(after 6). I'm going to the gun bash from 11-6 but I hve both prts in a drawer. A new piston and a yugo replacement valve( although I think I agree with cnc warrior). I'll pm you my number. If you bring your gun over I'll see if I see anything odd.

Here's another option for a replacement piston, but OldCarJunkie's offer sounds better! These may be Chinese piston, though.

PM'd you a thanks, but you certainly deserve a public Thanks for you generous offer.
Your offer actually woke me up to just pulling the piston out of my YUGO 59/66 and seeing how that fit. It falls right out of the Yugo, but sticks in the Chinese, so it looks like either I wasn't thorough in my cleaning or may need a new gas tube not a piston

Thank you Machodoc and CasualObserver for those sites.

Depending on where the burrs are on your piston, and how severe they are, you might just be able to gently dress them down with a jeweler's file or fine oil stone. There are three "rings" (bands) on the head of the piston, so if one of them just has a small place on it that you had to dress down a bit, it won't make any real difference.

Check for crud inside the gas tube. A little bit of corrosion or dried (cooked on) grease can create a bunch of problems. Put a bore light down in the tube and give it a good looking over ... then run a bronze bore brush down in it (I think .410 shotgun fits, but not sure) and clean it with that and solvent.

You can also roll the rod end of the piston on a sheet of glass or lucite to see if it's bent. That's a real possibility with a rifle that may have been fired without proper cleaning (before you got it, of course!).

Any chance the gas tube got knocked and dented? Should be a fairly simple problem to fix yourself. Even if you have to take a small file to something.

I remember Dawson's small arms in VA had some Chinese sks parts about 2 months ago. Could make a trip out of it if its not too far.
