88 GRAM CO₂ CARTRIDGES ARE ONLY COMPATIBLE WITH THE BYRNA MISSION-4 RIFLE.

Our box of two 88g CO₂ cartridges are a perfect fit for the Byrna Mission-4. Each cartridge (new) will be good for approximately 100 rounds (or 5x Mission-4 19-round magazines) at full speed. Punctured cartridges within the Mission-4 CO₂ buttstock will leak over time.

It is recommended to swap out punctured CO₂ cartridges and leave an un-punctured cartridge inside the Mission-4 CO₂ buttstock to avoid any compressed gas loss.

*Actual 88g CO₂ cartridge brand and packaging may vary depending on availability.
