Tactical Game Innovation FiSt-2 is a CO2 filling device designed for filling HPA cartridges, CO2 cartridges and Multi Range cartridges. The new FiSt-2 has a new sealing method, thanks to which the o-rings do not break even if you open the CO2 tank under pressure. In the previous FiSt model, it was possible to leak between the nozzle and the filling valve in cold weather, however, in the new model this is impossible according to the manufacturer. The new FiSt-2 filling device can now be used to fill CO2 and HPA cartridges. To fill the HPA cartridge, you simply remove the top part from the filling device and unscrew the CO2 adapter, you can directly attach the top part to the HPA bottle.
