NUPROL 4.0 (Black Gas)
Each bottle is made from sturdy alloy and three hundred grammes of gas that is under pressure. The length as well as its construction out of metal, the nozzle is designed to fit more securely into the gas valves on your magazines. Because of the potency of this gas, it is strongly advised that you should not use it with gas blowback weapons that have polymer or plastic slides, as it has the potential to harm or break those slides. This gas is ideal for Airsoft Players who utilise Gas Blowback Weapons and Rifles throughout the winter months but whose weapons are beginning to feel the effects of the cold.
