The CO2 cartridge is indispensable for the operation of air guns using CO2 as a means of propulsion. It takes the form of a 12-gram cylinder that is usually placed in the stock of the weapon. It is single-use and must be replaced when empty. The cartridge allows rifles, revolvers and CO2 pistols to fire in bursts: you do not need to rearm between shots to eject the pellet. On average, the 12-gram sparclette allows you to fire about 50 shots. At Jean Pierre Fusil, we offer it in batches of five, twenty and fifty units. Attention, for reasons of air safety, we cannot ship the cartridge to the DOM.
