Got a bunch of work finished tonight, thanks to adam45 for hosting.
The air passages are tapped for cocker barbs, the bolt and dump chamber valve now have manual control out the back. I'll still need to make some kind of oringed assembly to keep the dump chamber valve sealed while the cocking rod goes out the back, but that should be simple. Had to turn down an Automag ASA so that the pump rod can clear it.
LPR will go to a pneumatic trigger which will directly open the valve. There will be a backblock that will be attached to the bolt and cock the cocking rod and open the dump chamber to allow it to fill. :gunsfiring:
Here's my original concept video on YouTube if you didn't see it.
