Description.

The NUPROL Airsoft Gas 4.ZERO Black Gas 300g has been developed for airsofters running demanding gas blowback rifles, heavy bolt systems and upgraded DMR platforms that require significantly more operating pressure than a standard pistol. Delivering ultra-high-pressure performance while remaining completely silicone-free, this gas is aimed at players who prefer to lubricate and maintain their airsoft gun manually. By eliminating silicone oil from the gas itself, it helps reduce residue inside magazines, valves, hop units and inner barrels, making it especially attractive for precision-focused builds where consistency matters.

Unlike lower-pressure green gas options designed for lightweight pistols, the 4.ZERO formula is engineered to drive heavy steel bolts, reinforced recoil systems and long-travel bolt carriers with confidence. The high-pressure blend produces the force needed to cycle upgraded gas blowback rifles efficiently, even when additional aftermarket parts increase mechanical resistance. At the same time, NUPROL's advanced micro-dose trace additive expansion system helps maintain a smooth and predictable pressure curve, contributing to reliable cycling and more consistent FPS during extended shooting sessions. While many experienced players debate the benefits of silicone-free versus lubricated gases, those maintaining their own equipment often favour silicone-free products because they leave the hop rubber and barrel cleaner over time.

Performance in colder weather is another area where NUPROL 4.ZERO stands out. Gas-powered rifles naturally lose pressure as temperatures fall, but the carefully developed formulation is designed to promote stable gas expansion, helping heavy platforms continue cycling when standard gases begin to struggle. It is worth remembering that this is an extremely powerful gas intended for reinforced platforms only. It should not be used in standard pistols or lightweight gas blowback replicas unless the manufacturer specifically recommends it. For upgraded rifles, precision DMR builds and high-mass GBB systems, however, it offers the extra operating force many advanced setups demand while maintaining the clean-running characteristics that experienced airsofters appreciate.
