Description
The Byrna HD requires 12 gram CO2 cartridges, which should be swapped out if punctured to avoid air loss. These cartridges are only compatible with the Byrna HD when a Byrna Boost adaptor is installed.
It is recommended to swap out punctured CO2 cartridges and leave an un-punctured cartridge inside the Byrna HD to avoid any compressed air loss. The Byrna HD will puncture and fire the first round at the same time.
12 GRAM CO2 CARTRIDGES ARE ONLY COMPATIBLE WITH THE BYRNA HD WHEN YOU HAVE A BYRNA BOOST ADAPTOR INSTALLED.
