The Tank
Air systems are an essential part of every setup for Paintball or HPA Airsoft as they enable you to store the compressed air needed while you are out on the field. These CGE Tanks come pre-fitted with a first stage (or bottle) regulator which features a pressure gauge and filtered input fitting alongside a standard output thread on the top which is compatible with most HPA Airsoft regulators and any Paintball Marker.
 
These 13CI Air Systems are ideal for those who do not need the larger capacity of the bigger 48CI Air Systems or for those who utilise Air-In-Stock systems.
