This box of ten Byrna 8g CO2 Cartridges & Oiler are custom fit for the Byrna SD and HD
Launchers. Now including one CO2 cartridge with oil for simple maintenance with every 10th CO2 cartridges used. Each new cartridge will be good for 15 to 20 rounds (4 mags in a 5 round magazine) at full speed.
Punctured cartridges within the Byrna HD or SD will leak over time. We recommend you swap out punctured CO2 cartridges and leave an un-punctured cartridge inside the Byrna HD or SD to avoid any compressed air loss. The Byrna HD and SD will puncture and shoot the first round at the same time.
*Not compatible with Byrna LE, SDXL, HDXL or Launchers with Byrna Boost Installed. These require a 12g CO2 cartridge.
