The Silicone-Free Revolution:
The VAPOR™ line from Specna Arms was developed to offer players maximum control over their replicas, perfectly adapting to climate and mechanics. The Green variant, with its 145 PSI, represents the universal balance for use at temperatures of 10°C and above. Its greatest tactical advantage lies in the total absence of silicone oil in the mixture: the "dry" delivery prevents lubricant micro-particles from depositing on the inner barrel and hop-up bucking. The result? The Magnus effect imparted to the BB remains constant, and the trajectory stays flat and predictable even after prolonged bursts.
Stable Pressure and Reliability:
In addition to drastically increasing your setup's accuracy, VAPOR™ Green's eco-friendly formula ensures optimal valve sealing. The consistent pressure delivery avoids the annoying power fluctuations typical of cheaper propellants, guaranteeing a smooth gaming experience, crisp and satisfying recoil on full metal replicas, and perfect performance down to the last BB in the magazine.
| Variant | Pressure (at 25°C) | Recommended Use | Minimum Temperature |
|---|---|---|---|
| VAPOR™ Blue | 117 PSI | Pistols with polymer slides (e.g., Tokyo Marui) | From 15°C and up |
| VAPOR™ Green | 145 PSI | Universal use; metal slides and standard replicas | From 10°C and up |
| VAPOR™ Red | 188 PSI | High-performance GBB replicas with reinforced internals | From 5°C and up |
| VAPOR™ Black | 217 PSI | High-power gas rifles; ideal for winter | From 0°C and up |
Pro Maintenance Tips
Laser-accurate shots and DIY maintenance: Choosing a "dry" (silicone-free) gas like this VAPOR Green is the tactical move for pro players! Classic lubricated gases spit oil particles onto the hop-up bucking with every shot, causing it to lose friction. With this Specna Arms gas, your air assembly remains perfectly dry, and accuracy is absolute. Remember the golden rule, though: lubricating your replica is now up to you! After each game, disassemble the slide and manually apply a couple of drops of silicone spray oil to the slide rails, magazine valve, and nozzle o-ring to prevent seals from drying out.
Summer heat and polymer slides: The 145 PSI of this gas is magnificent for making Full Metal replicas (like WE, VFC, KWA, etc.) "kick" properly from April to October. However, be very careful if you use Japanese pistols with ABS slides (like classic original Tokyo Marui models): in summer, under the scorching sun, thermal expansion combined with 145 PSI could literally crack the plastic slide. On the hottest summer days with polymer replicas, always opt for milder pressures (like VAPOR Blue at 117 PSI).
