Nobody really ever understood how it worked :D
I think he posted a few diagrams. I tried to do a shell ejecting but I think there are easier ways than how he did it...

Take a gander at JSR's hybrid and pneumatic cartridge prototype threads, as both contain a build prototype which offers shell extraction.

In IKM3T's design, the force of the spring ejected the shell, but there are certainly other ways to do it. his "bolt" had a coupling on the end, so it just slid over the front of his PVC shells
