So the pressure ramps up as the bolt traverses forward. I'll assume the patents are already filed, can you tell us any kind of details just yet?
Specifically-
1) Is it a two-stage design, where the surface area is drasticly increased after the bolt has travelled X distance (like the two-stage ram I designed) Or is it a gradual increased based on some kind of flow-throttling.
Hey Curt, I do remember those images and discussion. And although I haven't yet actually had a level 10 in my hands I think that is kinda how it works. ;) I'm not sure you even need a second larger surface area... Although the level 10 may have one, if you just reduce the area on the bolt stem, then with the current operating pressure the force will be much lower and then at a certain point open up the transer path to allow the normal firing burst of air.
You needn't open up the path until the bolt is almost closed so you will have a low bolt force on most of it's travel and at least enough of the travel to cover any chances of chopping a ball.
I expect the bolt has to get almost all the way forward until the full gas blast is released. I have no idea if this will help with the blowback issue but it might do... I remember some of the blowback issue being related to a small diameter bolt in the mag fitting into larger diameter barrels.
