NUPROL Airsoft Gas 4.ZERO

Ultra-high-pressure silicone-free gas engineered for clean, controlled, powerful performance in tuned heavy GBB platforms.

Product Features:

• Ultra-high-pressure silicone-free blend
• Ideal for heavy rifles, bolts and DMR systems
• Trace additives for rapid, stable expansion
• Clean-running interior for precision setups
• Supports refined user-controlled lubrication
• Consistent behaviour in harsh conditions
• Engineered for advanced performance builds

NUPROL 4.ZERO is a silicone-free ultra-high-pressure gas created for the most demanding GBB platforms and the players who tune them. Delivering the same raw power as NUPROL 4.0 but without silicone oil, 4.ZERO provides maximum output while maintaining a clean internal environment—essential for precision hop units, tight-barrel systems and high-end custom configurations.

To ensure stable operation at extreme pressures, the blend features NUPROL’s advanced trace additive expansion system. These micro-additives accelerate expansion and stabilise pressure through each firing cycle, giving heavy platforms the consistent power needed for reliable recoil, cycling and accuracy.

By pairing 4.ZERO with controlled applications of Silicone Spray Oil, players can build lubrication routines that perfectly match their platform’s requirements. For high-mass, high-performance GBB systems, 4.ZERO offers unmatched control and output.

Range Overview:

The NUPROL Gas Range is the flagship product line that gave the brand its name — “NUPROL” meaning New Propellant. From the earliest development stages, the goal was simple: deliver a modern, high-performance gas system engineered specifically for airsoft, offering players reliable pressure levels, predictable cycling and long-term equipment care. Today, the range spans multiple pressure grades and silicone-free alternatives, each built to serve different replicas, climates and performance requirements. Every blend is formulated on a refined propane base and enhanced with NUPROL’s trace additive expansion system, a micro-dose package that improves gas expansion, stabilises pressure and maintains consistent FPS shot after shot. Whether players need a low-pressure option for lightweight platforms, a balanced all-rounder, a high-pressure solution for full-metal builds or an ultra-power option for heavy GBB rifles, the NUPROL Gas Range delivers clean, dependable performance across all levels of play. Developed through continuous improvement and user feedback, the range reflects NUPROL’s commitment to engineering airsoft propellants that players can trust — from casual skirmishers to advanced technicians building precision platforms.
