Byrna 12 Gram CO2 Cartridges – 10 Cartridges

The Byrna 12 Gram CO2 Cartridges – 10 Cartridges are custom fit for the Byrna HD Launchers with the Boost adaptor. Each cartridge (new) increases to a 30 shot capability at full speed. Punctured cartridges within the Byrna HD and Byrna TCR will leak over time. It is recommended to swap out punctured CO₂ cartridges and leave an un-punctured cartridge inside the Byrna to avoid any compressed air loss. The Byrna will puncture and fire the first round at the same time.
