NUPROL Ultimate Power Black Gas 4.0 (200 PSI)
Ultimate Power Black Gas 4.0 by NUPROL is the strongest airsoft gas, providing maximum power even in cold conditions. It’s designed for use in spring, autumn, and especially winter, delivering optimal performance at 200 PSI at 25 °C in gas-powered airsoft guns with upgraded trigger mechanisms and internals. This gas is perfect for high-powered GBB rifles. Thanks to a durable metal nozzle, magazine refilling is easy and safe.
