High quality precision cartridges 12g Co2 capsules by Umarex.
Umarex CO₂ capsules are distinguished by constant high pressure and uniform quality.
The constant pressure ensures that each shot is the same as the previous one.
Pack of 10

In order to extend the durability of the valve and to avoid any jamming or malfunction of your airgun, we recommend you exclusively use Umarex or Walther Co2 capsules.
Other manufacturers have different size tolerances which might cause blocking of your airgun or their capsules have a burr at the top end which could destroy the seal.
Additionally not all manufacturers have the Co2 gas filtered before filling it into the capsules.
This will cause an increased soiling of the valve which could also lead to a dysfunction of the airgun.
