BYRNA 8 GRAM CO2 CARTRIDGES

8 GRAM CO2 CARTRIDGES ARE ONLY COMPATIBLE WITH THE BYRNA HD AND BYRNA SD.

*Not compatible with Byrna SDXL or HDXL or Launchers with Byrna Boost Installed

Our box of ten 8g CO₂ cartridges are custom fit for the Byrna SD and HD Launchers. Now including 1 CO₂ cartridge with oil for simple maintenance every 10 CO₂ cartridges used. Each cartridge (new) will be good for 15-20 rounds (4 mags in a 5 round magazine) at full speed. Punctured cartridges within the Byrna HD will leak over time.

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.
