The Byrna 8 Gram CO2 Cartridges are a box of ten 8g cylinders custom fit for the Byrna CL, SD, EP and HD launchers (Byrna Technologies part no. CO2310). Byrna includes one CO2 cylinder with oil in the box for simple maintenance, to use once every ten cylinders. They are the smaller size, so they do not fit the LE, CL-XL, SDXL or HDXL, or launchers running the Byrna Boost adaptor.

Key Specifications
