Byrna's twin pack of 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 60 rounds (or 3x 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.
 
It is recommended to keep an unpunctured cylinder in your launcher at all times for self-defense purposes.  Punctured cylinders within your Byrna Launcher will leak over time.
