- 12g CO₂ Power Capsule by Borner, designed for air pistols and rifles. These CO₂ cartridges propel pellets using compressed carbon dioxide. A single capsule provides enough power for approximately 60 shots.

12g CO₂ Capsule by Borner is a high-performance power cartridge designed for air rifles, ASG pistols, and RAM guns using rubber balls. Thanks to the unique properties of compressed carbon dioxide (CO₂), Borner capsules deliver consistent pressure and excellent efficiency throughout the discharge cycle until most of the gas is depleted.
Each capsule enables up to 60 shots, making it an ideal choice for CO₂-powered pistols, revolvers, and carbines. For a standard 500-round pellet pack, it is recommended to purchase at least 10 CO₂ capsules, each with a 12g capacity.
The Borner 12g capsule is fully compatible with all major CO₂-powered airgun brands, including Ekol Voltran, Niksan, Borner, WinGun, Umarex, and more.
This product is widely used not only in air rifles, but also in:
- ASG replicas (Air Soft Guns),
- RAM guns (Real Action Markers),
- select paintball markers.
Note: Once the capsule is punctured, it should be removed within 48 hours to prevent damage or wear to the seals. Gas efficiency may decrease in lower temperatures.
