since I didn't install the cup that's for guiding the shell for eject function, also I've found there is a bit tie between bolt and the end cap when shell is in the chamber, for the shell sits and holds better in the bolt within the chamber being ejected, grinding the front of the bolt a bit (like a cup shape to let the end cap sit in) could improve it. This idea I learned from the bolt design for Tanaka M870. So far it's working okay for short period of time, need to see the long run tho.
The video link I've seen it already, good idea if, 1, you have the compressor, 2, you don't mind to charge 10-12 second each shell, 3, you like the high power. But I don't have a compressor, I don't want to take so long to recharge, and I don't even need that higher power! So I keep the co2 charger is fine for me
