    Unhappy Yugo AK gas leak... Fix?

    I think I've finally pinned down the cause of the failure to eject problem of my fixed stock Yugo AK. I noticed a huge amount of carbon build up around the gas block today, after firing less then 2 magazines. The gun had been well cleaned the day before.

    I figure enough gas is escaping that the bolt carrier doesnt have enough energy to fully reciprocate, the shell casing not hitting the ejector hard enough to eject it fully. When the bolt carrier begins to shoot forward, picking a round up off the magazine, it gets stuck between the chamber and the spent shell casing.

    The problem now is, how do I fix this? Any suggestions?

    Someone took one apart once and there was a half-cut pin IIRC that was how it works. Sounds like maybe yours is corroded to the point that it is venting to the outside instead of down the gas tube...?

    Wonder if you can drill out the pin and insert a new one?

    I had the same problem. Scroll about half way down this thread.

    Oh, and be careful. The one that I had would spit high speed particles back into my face.

    It is a DCI receiver. Great buy, BTW.

    Thanks for the offer, but for me it was a time consuming job. I would have to charge way too much. You might give the Hotbarrel a try. Or get a replacement GB from SRH. If your block isnt too corroded, you might even get away with replacing only the pin. That would be the easiest and least expensive fix.
