The Green Gas NUPROL 4.0 Premium Black is a very high performance propellant for gas airsoft replicas (GBB/GBBR), specifically formulated for use at low temperatures, starting from +3°C. It is therefore ideal for winter use, but can be used all year round with powerful replicas, such as GBBR rifles, GBB pistols with metal slides and NBB (Non BlowBack) sniper rifles.

This gas, often called "Black Gas" in airsoft jargon, offers several advantages:

  • Increased FPS (Feet Per Second) and recoil: Thanks to its formulation, it provides more power than standard Green Gases, increasing the BB's exit velocity and recoil (in blowback replicas).
  • Exceptional trajectory control: Guarantees a more stable and precise trajectory.
  • Constant pressure stabilization: Maintains constant pressure inside the magazine, ensuring consistent performance.
  • Suitable for low temperatures

NUPROL states that this gas allows you to get over 20 more shots per magazine charge, compared to other gases.

IMPORTANT: This gas is very powerful and is not recommended for use with:

  • Pistols with plastic slides.

It is recommended for:

  • Powerful GBB/GBBR replicas (with metal slide).
  • Upgraded replicas.
  • NBB sniper rifles.
  • Use in IPSC competitions.
