I'm pretty sure you're suppose to drill it out and then replace it with a new one. This is what I heard from Sniper69... Might want to send him a PM.

If you look at the front of the carrier there is a pin that has to be removed. Looking closely at approximately the 3 or 9 oclock position, you should see a real faint circular mark where the pin is located. Drill out the pin. After the old gas piston is removed and you are installing the new one, snug it down and then back it out almost a 1/4 of a turn. The gas piston isn't supposed to be tight but have some slight play in it (that's why you back out about a 1/4 of a turn). Using the existing hole in the bolt carrier drill through it and the new gas piston so that you can install a new pin. Then reinstall a pin that is a press fit, or use your vise. Then peen the ends and smooth the area. Also if you use an 1/8" drill bit to drill the hole when the new gas piston is installed you can use an 1/8" roll pin. If you are looking for the actual pins that go into the gas piston, k-var and aa-ok sell them. I have heard where some use a drill bit or a piece of rod the size of the hole. Hope this helps.Deadeye said:

No, you didn't screw up. I find it easier to punch the old one out. If you're careful, you can save the pin and reuse it. Like has been said, use the bolt carrier to locate and drill the new hole. I then take the gas piston and open the hole in the piston itself about .010" or so larger because the gas piston isn't supposed to be a tight fit in the AK. With a little slop, the stress is on the threads instead of the pin. Reinsert the pin in the hole, back it up on something solid and then use a punch to peen the end of the pin over. Easier to do than explain.
