I'm going to crosspost this here as everyone seems to be a big help!
I have this old Macdev asa from an '06 Cyborg that I need some help with. I'll post some pictures below but here's the issue. The pin that depresses the valve on the tank is missing and I'm trying to find a replacement, or something that can serve as one. I have pulled the thing apart and the diameter of the internal o-ring fits snugly around a cocker's 3-way arm that leads to the trigger. Does anyone have experience with this asa, or know where I might get a replacement part, or hell, can tell me the diameter of the internal o-ring so I can ghetto something together?
Here are some pics:
Internal o-ring is the one shown
Internal assembly. Can see the size of the 3-way arm in the background. Thought of cutting off a nail and seeing if it would work, but it wont seal so it would just bleed.
Don't want to leave people hanging who might find this thread later. Bourke emailed me through tech support with the following response:
No worries, that ASA takes a simple 3mm diameter pin in a 40mm length. We have the pins here, so you can get one from us in Australia, or you can user anything the same size if you like.
