Ultra-high-pressure 300g gas delivering maximum power, strong recoil and stable performance for heavy GBB platforms.
 
Product Features:
Ultra-high-pressure formulation
Designed for heavy rifle and DMR platforms
Strong recoil and FPS stability
Silicone-lubricated for seal protection
Trace additives enhance expansion rate
Reliable cycling in cold environments
Supports demanding, high-mass operating systems
 
NUPROL 4.0 is the most powerful gas in the NUPROL range, engineered specifically for heavy GBB rifles, DMR setups and high-mass slide or bolt systems that demand maximum operating pressure. Delivering authoritative recoil and stable FPS output in even the harshest conditions, 4.0 ensures heavy platforms cycle with confidence where standard gases lose performance.
 
To maintain reliability under extreme load, the blend incorporates NUPROL’s highest concentration of trace additive expansion technology. This engineered additive package accelerates gas expansion and helps stabilise pressure during long bursts, sustained semi-auto fire or cold-weather use.
 
Silicone lubrication supports the replica’s seals and valves against the additional operating forces, maintaining long-term performance. For players who push the limits of GBB realism and want maximum power on every shot, NUPROL 4.0 is the definitive high-pressure solution.
