Our box of ten 8 gram CO2 cartridges are custom fit for the Byrna HD/SD & the new EP. Includes 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 will leak over time.
It is recommended to swap out punctured CO2 cartridges and leave an un-punctured cartridge inside the Byrna HD/SD to avoid any compressed air loss. The Byrna HD will puncture and fire the first round at the same time.
Please Note: No discount codes can be used for Byrna Launchers or Byrna accessories.
