Aluminium CO2 charger for your airsoft grenades. Allow to insert standard 12g CO2 capsule and fill gas grenades with CO2. You can fill it 3-4x and then replace capsule with the new one. Advantage is much higher pressure = fps. Due to high pressure is harder to press grenade launcher trigger. Shot is very noisy!
Notification: Not suitable for Gas Blowback magazine - may cause an explosion of the magazine. Due to very high pressure, gun is also not able to press release valve.
