Byrna 8 Gram CO2 Cylinders

These Byrna 8-gram CO2 cylinders are custom fit specifically for use with the Byrna SD Launcher to deliver reliable, full-speed propulsion. Each newly installed cylinder powers approximately 15 to 20 rounds before needing replacement, ensuring consistent performance during training or defense scenarios.

The 10-pack includes one specialized CO2 cylinder pre-filled with oil, allowing for regular maintenance and internal lubrication every 10 cartridges used. This integrated care routine helps preserve your launcher's internal seals and ensures smooth mechanical operation over extended use.

Designed for self-defense preparedness, launchers should be stored with an unpunctured cylinder installed so they remain ready for immediate deployment without pressure loss. Note that these cartridges are engineered exclusively for standard Byrna SD models and are not compatible with launchers equipped with the Byrna Boost accessory.
