Ejection Chute
So, basically, they use a variation on the same kind of action that's used to load the next round from the magazine.
The only real difference being that, with the barrel pointed upward, any brass already in the ejection chute would slide back. What do they use to keep prior spent casings from interfering with the next one being ejected?
I mean, something in the chute that makes it easy for brass to slide forward by not back sounds good; I'm just not sure what material would do that without heat/fouling/other problems.
And then there's the follow-up on a failure-to-fire, with a complete cartridge being sent down the chute.
Many questions. Look forward to seeing one in person.
hksw:
How the system works is the extractor, after the bolt assembly is drawn back under recoil, tilts the empty case upward (inside of the gun unseen). At this point the empty case is pointed at a channel located above the barrel. You can see it on the posted tech data sheet of the gun on the first page of this thread. As the bolt goes forward to complete its cycle, the casing starts to enter the channel and the extractor gets push down to engage the next (live) round going into the chamber. When the extractor depresses, an extension in the bolt carrier (not sure if it is called that) pushes the empty casing further into the channel. The force of the bolt/bolt carrier going forward is what kicks the casing out of the chute.
