    I have a Daystate Mk4iS that has air leaking out the barrel. The leak seems most severe when the air reservoir is at a low pressure. I’d sure appreciate any information on which o-ring needs replaced.

    I personally would just go ahead and replace them all, see what happens, go from there.

    It’s your delrin Seal on you valve or the oring around the metal seat, that’s the only 2 seals that prevent it from leaking out the muzzle.

    After more research it seems I will need a special tool to access the valve on the Daystate. Anyone know where to get one?

    Dirte:
    I’m not sure. I haven’t gone through the trouble of taking apart the gun since I know I need a “special” tool. Thanks for the link. I’ll look into it.

    aa_limited:
    It is difficult to tell. It probably starts leaking long before I realize it. I filled it up to a full 230 BAR a few days ago and it was down to 180 the next day. This was after the gun emptied on me. Maybe the air settled that much after filling it form empty? I shot it a bit down to 140 BAR and it seemed to hold air for a couple days. I shot the pressure down an unknown amount further and then started hearing air leak out the breach and barrel. As the pressure dropped the leak got stronger.

    Dirte: I believe that is a wrench to remove the 12 FPE limits for non FAC airguns. I found a video of someone taking apart their gun on YouTube use the tool. It is a long bar (at least a foot) with what appears to be a pronged end. The end is not clear and I could be mistaken.

I came across it and bought one just in case I ever needed one. I could not tell you where it’s used either. I just hear others reference it.
