At this moment the internals are all in, the regs are built (and running fantastic), the gun is fully assembled except for the updated switch.
We had one part we decided up upgrade before we showed off the first 10. That is the switch that does the transferring of air to cycle the piston. We had some bits made by a third party but they were substandard.
We have an upgrade that works, and we just finalized it this morning. I was about to make a FB post on the parts being ran. After that we have 1 more bit to produce on the switch. Then they are a go.
