Byrna 8 Gram CO2 Cartridges are sold in boxes of 10, one of which includes oil for basic maintenance. They are custom fit for the Byrna HD and SD Launchers and each new cartridge is good for between 15-20 projectiles in rapid succession.
NOTE: Punctured CO2 cartridges within the Byrna launchers will leak over time.
It is recommended to swap out punctured CO2 cartridges and leave an un-punctured cartridge inside the Byrna launcher to avoid any compressed gas loss. The Byrna launcher will puncture and fire the first round at the same time.
