Air cartridge, Refillable, Proton-X2 17947
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-effective 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 adaptor Ref. 18321 is required for refilling.
Note that results may vary depending on the internal CO2 system and build quality.
