Byrna HD 12 Gram CO2 Cartridges (10pk)

Our box of ten 12g CO₂ cartridges are custom fit for the Byrna Launcher (requires the Byrna Boost add-on or the Byrna XL Launcher) to add a larger CO2 capacity than the standard 8g cartridges.

It is recommended to swap out punctured CO₂ cartridges and leave an un-punctured cartridge inside the Byrna HD to avoid any compressed air loss. The Byrna HD will puncture and fire the first round at the same time.
