Byrna 88g CO2 Cylinders

88 GRAM CO2 CYLINDERS ARE ONLY COMPATIBLE WITH THE BYRNA MISSION-4 RIFLE. Our box of two 88g CO2 cylinders are a perfect fit for the Byrna Mission-4. Each cylinder (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 cylinders and leave an un-punctured cylinder inside the Mission-4 CO2 buttstock to avoid any compressed gas loss. *Actual 88g CO2 cylinder brand and packaging may vary depending on availability.
