These 8-gram CO2 cartridges are the power source for the Byrna HD personal security launcher, sold in a convenient pack of ten. The Byrna system uses compressed gas to launch kinetic and chemical irritant projectiles as a less-lethal home and personal protection option, and a fresh cartridge is what drives every shot. Stocking up on spares means your launcher is always ready for practice sessions or when you need it most. Each cartridge is a standard threaded 8-gram size, and keeping a supply on hand is simply smart ownership for anyone who keeps a Byrna for training and security.
