Air cartridge, Refillable, Proton-X2
HPA capsules (High Pressure Air) are the latest innovation in the Airgun industry. Using a container similar in size and shape to a CO2 capsule, the HPA capsule is a cost efficient tool in your Airgun and Airsoft arsenal. The refillable valve featured on the capsule allows for easy refilling. An air pump conveniently stored at home can for example be used to refill the capsule.
Using this system also means the capsule pressure can be adjusted making the muzzle velocity in the Airgun adjustable.
Our HPA capsule adapter is required for refilling.
Note that results may vary depending on the internal CO2 system and build quality.
