Sorry for the delay. I tested the magazine with a couple of snap caps. It works quite well though I can see it jamming pretty easy. Still, a very neat mechanism from a design standpoint.
Here's some pics of the bolt disassembly.
Step 1: Make sure the magazine disconnect is in the forward position.
Step 2: With a really thin blade screwdriver, get under this little lever.
Step 3: With the release lever in the upright position, the connector can be lifted up.
Step 4: With the connector lifted up, the extractor can be lifted off the bolt and out of the magazine bar.
Step 5: Withdraw the bolt from the rifle completely by holding the trigger down and pulling the bolt out.
That's all there is to it. The Forgotten Weapons video on this firearm says he found some directions for disassembly and he referred to them as "scary."
The only thing even a little scary about this is the fact you're working on a $3,000 rifle...of which maybe only a few hundred exist. Other than that, this is no more complicated than any other rifle.
