How Many Shots Per Cartridge?
A new, fully charged 88g CO₂ cartridge delivers approximately 60 rounds at full velocity in the Byrna Mission-4. This equals roughly 3 complete 19-round magazines. Shot count may vary based on ambient temperature — colder conditions reduce CO₂ pressure and may lower the per-cartridge round count.
Safety & Storage Notes
⚠️ Punctured CO₂ cartridges stored inside the Mission-4 buttstock will leak pressure over time. Always swap out punctured cartridges and store an unpunctured cartridge in the buttstock to maintain readiness.
Store cartridges in a cool, dry place away from direct sunlight and heat sources. Do not expose to temperatures above 120°F (49°C).

Frequently Asked Questions
- Are 88g CO₂ cartridges compatible with other Byrna launchers?
- No. The 88g CO₂ cartridge is exclusively compatible with the Byrna Mission-4 rifle and its integrated CO₂ buttstock system. All other Byrna launchers use either 8g or 12g CO₂ cartridges. Using the wrong cartridge size will not work and may damage your launcher.

- Each new 88g cartridge delivers approximately 60 rounds at full speed in the Byrna Mission-4, which equals about 3 full 19-round magazines. Shot count may be lower in cold weather due to reduced CO₂ pressure.
- Should I leave a CO₂ cartridge in the Mission-4 buttstock when not in use?
