So far I have not heard much at all about the internals, other than its a FASOR designThis new patented technology sounds interesting. I think this may be a nice contender, pending some on-paper information.
For those who wonder what a Fasor is..
Fasor or Forward Air Spring Operated Return - bastically means that instead of using air from the solanoid on the ram to push the bolt forward and return it to the 'ready' position, it uses a spring to return the bolt. - (Some spool valves have attempted to apply this principle like the Shocker Spring mod, or the Ion Lucky Stage 2 Bolts with return Spring - which helps reduce dwell)
this is considered to be of an older design ala Rex Type-R, RX, R3 - but it has its advantages such as being easier to manufacture and maintain by the end-user, and some would argue as being more air effecient.
But i dont know much else about them - I hope that description is right/useful
