I bought a refurb Seneca Eagle Claw and within a few weeks it started leaking. Took it apart and the screw was missing from the check valve, I fixed it and it's working but I'd like a replacement. Pyramyd Air sent me a Sumatra check valve, which when you look at the part on their website it's correct, but it's not that part it's totally different. PA sux for trying to get a person on the line. I love the gun and want to keep it I just want a new check valve so does anyone know where I could buy one? I call Air Venturi direct and their phone system put me through to PA tech dept where I'd have to sit on hold again.
