NUPROL Ultra High Pressure Airsoft Gas 4.ZERO (Black Gas) 300g
For players running upgraded gas blowback rifles, heavy bolt systems or precision DMR platforms, the NUPROL Ultra High Pressure Airsoft Gas 4.ZERO (Black Gas) 300g delivers the extra power needed to keep demanding replicas cycling reliably. Developed as NUPROL's highest-pressure silicone-free gas, it's designed specifically for reinforced gas blowback airsoft guns that require greater operating pressure than standard green gas can provide. If you're looking for maximum performance without introducing silicone into your internals, this is the gas to reach for.
The silicone-free formulation helps keep magazines, valves, hop-up units and inner barrels cleaner, making it a popular choice for experienced airsoft players who prefer to lubricate and maintain their replicas manually. By reducing unwanted oil residue, the 4.ZERO formula supports consistent hop performance and allows precision components such as tight-bore barrels and upgraded buckings to perform at their best. NUPROL's advanced micro-dose trace additive expansion system also promotes efficient gas expansion, helping deliver stable FPS and a consistent recoil impulse throughout each magazine.
Ultra-high pressure makes this gas particularly well suited to reinforced gas blowback rifles, heavy steel bolt carriers and upgraded recoil systems that require additional force to cycle correctly. It also performs exceptionally well during colder weather, where lower-pressure gases can struggle to maintain reliable operation. This makes it an excellent option for winter skirmishes or players using high-mass GBB platforms that demand dependable performance in challenging conditions.
As this is an ultra-high-pressure gas, it should only be used in compatible reinforced gas blowback rifles and platforms where the manufacturer recommends its use. When paired with suitable airsoft guns, the NUPROL 4.ZERO Black Gas provides powerful, consistent performance with the clean-running benefits of a silicone-free formula, making it an excellent choice for serious gas blowback enthusiasts.
