Nuprol 4.ZERO Silicone Free Black Gas
£16.99
Nuprol 4.ZERO Silicone Free Black Gas is an ultra-high-pressure 300g airsoft gas designed for heavy bolt GBB rifles, DMR replicas and reinforced gas blowback systems. The silicone-free formula keeps hop units and inner barrels cleaner, therefore it suits upgraded airsoft guns requiring controlled lubrication and stable recoil performance.
The Nuprol 4.ZERO blend delivers maximum operating force since steel bolts and high-mass recoil systems create greater mechanical resistance. Its trace additive expansion system improves gas efficiency during rapid firing, thus maintaining consistent FPS and reliable cycling in cold weather conditions.

Description
Nuprol 4.ZERO Silicone Free Black Gas is an ultra-high-pressure 300g airsoft gas engineered for heavy bolt rifles, DMR builds and reinforced gas blowback systems. The silicone-free formulation reduces residue contamination, therefore it suits precision-tuned airsoft replicas requiring controlled lubrication routines and stable internal performance.
Designed for extreme mechanical load, Nuprol 4.ZERO delivers the operating force required for steel bolts, extended recoil systems and upgraded GBB rifle assemblies. The ultra-high-pressure blend maintains reliable cycling and recoil consistency since high-mass components demand stronger gas expansion during operation.
Key Features
- 4.ZERO ultra-high-pressure formula: Produces maximum gas output for heavy bolt rifles, DMR replicas and reinforced gas blowback platforms.
- Silicone-free composition: Keeps hop rubbers, valves and inner barrels cleaner, consequently supporting precision-focused maintenance routines.
- 300g full-size gas cylinder: Provides extended usage capacity for skirmishing, testing and high-volume firing sessions.
- Trace additive expansion system: Promotes rapid and stable gas expansion, thus improving recoil consistency and FPS stability.
- Optimised for extreme load: Supports steel bolt carriers, upgraded recoil assemblies and extended travel GBB systems operating under increased resistance.
- Cold weather capable: Maintains dependable cycling performance in harsh environments where lower-pressure gases may lose efficiency.
Engineered for Heavy Recoil Gas Blowback Builds
Nuprol 4.ZERO is developed for advanced gas blowback airsoft rifles that require uncompromising pressure output. Heavy steel internals and reinforced moving components increase operating resistance, therefore lower-powered gas blends may fail to cycle consistently under demanding conditions.
The controlled pressure curve allows the system to maintain reliable recoil behaviour while reducing erratic gas performance during sustained firing. This makes Nuprol 4.ZERO suitable for DMR rifles, high-mass GBB rifles and upgraded training replicas using reinforced internals.
Silicone-Free Airsoft Gas for Precision Maintenance
The silicone-free blend gives users complete control over lubrication management since no silicone oil passes through the firing assembly during use. As a result, hop-up units, tight bore barrels and internal seals remain cleaner during prolonged operation.
NUPROL’s micro-dose trace additive expansion system improves pressure efficiency inside the magazine, consequently supporting stable recoil impulse and shot-to-shot consistency in cold-weather skirmishing or intensive firing scenarios.
