The Nuprol Premium 4.0 is designed to be used in particularly cold conditions (3 – 20°C), where standard green gases won’t offer a proper thrust for gas guns. The gas is also more powerful than a standard green gas, so it’s compatible also with GBB guns that have a heavy slide. The thrust of the gas has been optimized so that the changes in muzzle velocity are as small as possible between shots. The black 4.0 gas is the most powerful of the Nuprol Premium series' gases and it withstands differences in temperature better than any other gas. This means that it’s perfectly suitable to be used in our beloved Finland! The gas bottle has a metal nozzle and a cap that protects it from hits during transport.
Note! The manufacturer recommends that you let the gas settle in the magazine before use – thus ensuring best possible functionality!
Gas bottle volumes
In airsoft, it has become a custom to state the gas bottle volumes according to the volume of the whole bottle in milliliters. The amount of the gas itself in the bottles is always smaller than the volume of the bottle. Check the volume of the bottle and the amount of gas in the product description.
