Prevents liquid Co2 from entering the marker, you wont need one because you are getting CA

Expansion chambers are kind of a rip off. They work to some degree, but in no way keep all liquid out. Only buy a expansion chamber if you want a foregrip. The only thing that really prevens liquid is a anti siphon tube... unless you run it on a remote.

It makes everyshot shoot with the same amount of air pressure. Every shot it consistant. If you gun doesn't move, your shot will hit pretty close to the same spot.
