8 gram CO₂ cylinders are compatible with the Byrna CL and Byrna SD launchers.
Each pack contains 10 cartridges, with one CO₂ cartridge containing oil for simple maintenance. For Byrna CL models, it’s recommended to initially use the oil cartridge after approximately 30 rounds.
It is recommended to keep an unpuncturedcylinder in your launcher at all times for self-defense purposes. Punctured cylinders within your Byrna Launcher will leak over time.
