Byrna 8-Gram CO2 Cartridge – 10 Pack

These 8g CO2 cartridges are a custom fit for the Byrna HD & SD. Each cartridge (new) will be good for 15-20 rounds (4 mags in a 5 round mag) 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 a compressed air loss. The Byrna HD & SD will puncture and fire the first round at the same time.
