Okay, to answer my own question with a Philips screwdriver:

THERE ISN'T ONE.

The mag is upside-down from how a removable traditional box mag would work. You fill it with darts from the bottom, and pull the darts back out by hand one at a time to breech-load them when the priming handle is at the rearward position.

The wiki page for this thing isn't very helpful, I think I'll be rephrasing some parts of it and throwing some internals pics on there too.

Sure LOOKS cool... a little like a P90 back before Stargate SG-1 made P90s uncool. But it's not. It's the clunky core of an underpowered single-shot sniper rifle that only a left-handed nearsighted sniper would want to use.
