    lol, its the dimensions of the fill valve thread i have, it was in my boot, so i measured it...

    i have no idea what thread it is, only thing near the od (outer diameter) is no.10 ASF but the pitch and tpi is out... the id is only rough and is taken from the valve stem under the thread

    as i said, its easier to retap

    That sounds like a future gas powered fill valve missile. Fill valve missile to the testicles.

    It does indeed, but it's held gas for a week now

    Does anyone know of the PROPER valve that will fit these guns?

    Many people have them so someone
    Must know

    In the spirit of sharing, I can tell you that a Tokyo Marui M92 magazine fill valve will fit the ACM Mossberg 500 gas block. You just need to cut it down to the same length as the valve in the shotty. Now seeing as your gun didn't come with one, I'd say cut about half the valve away, then see if it fits, if not cut a bit more.

    You'll know if it fits as it will stick up out of the gas block if it doesn't fit.

    I did this to the gas block in my 8mm version last night and it works perfectly.

    *edit: Just to clarify, when you get the valve, take it apart by unscrewing the bottom, then you will have the valve and spring pieces separate and away from any cutting device you use. The bit you will be cutting will be the long tube piece.
    It will take less bullets to kill him now than if we wait for him to turn into a zombie.

    The elderly. They seem nice enough, but can they really be trusted ?
