BYRNA 8 GRAM CO2 CARTRIDGES + OILER 10 Pack

8 gram CO2 cartridges are designed specifically for the Byrna HD and Byrna SD launchers. This pack comes with ten 8g CO2 cartridges and one CO2 cartridge with oil for easy maintenance. After every 10 cartridges used, use the oiled one to keep your launcher in top - shape. Each new cartridge can fire 15 - 20 rounds at full speed. Once punctured, cartridges in the Byrna HD will gradually leak. It's best to replace punctured cartridges and leave an un - punctured one in the Byrna HD to prevent air loss. The Byrna HD punctures and fires the first round simultaneously. Note that there are shipping restrictions. This product cannot be shipped to Hawaii, or to certain cities in New York like Bronx, Brooklyn, Manhattan, New York, Queens, Staten Island, Yonkers, and also not to San Francisco, CA.

Using these cartridges is simple. Just load them into your Byrna HD or Byrna SD launcher. When you're ready to fire, the launcher will puncture the cartridge and fire the round at the same time. Each new cartridge can give you 15 - 20 rounds at full speed. After using 10 cartridges, use the oiled CO2 cartridge included in the pack for maintenance. This will help keep your launcher working well. When a cartridge is punctured, it will start to leak over time. So, it's important to swap out punctured cartridges and leave an un - punctured one inside the launcher to avoid losing compressed air. Also, be aware that due to shipping restrictions, you can't get this product shipped to Hawaii or some specific cities in New York and San Francisco, CA.
