Brute Power for Reinforced Replicas:
When the cold sets in or your mechanics need an extra boost, Specna Arms' VAPOR™ line responds with the Red variant. Delivering a formidable 188 PSI pressure (measured at 25°C), this gas is specifically formulated for high-performance GBB replicas. It is the ideal companion for heavily modified pistols, equipped with solid metal slides, reinforced tappet plates, and custom trigger groups, as well as for gas assault rifles (GBBRs) that struggle to cycle in low temperatures. It guarantees crisp, powerful recoil and reliable operation even when the thermometer drops to 5°C.
Absolute "Silicone-Free" Precision:
Power is nothing without control. Just like the other variants in the VAPOR™ series, Red Gas is completely free of silicone oil. This feature ensures that no lubricant particles are deposited inside the barrel or on the hop-up nub. The Magnus effect imparted to the BB will be consistent and perfect shot after shot, ensuring tight trajectories and extremely close groupings, a fundamental requirement for those using modified, high-performance replicas.
| Variant | Pressure (at 25°C) | Recommended Use | Optimal Temperature |
|---|---|---|---|
| VAPOR™ Blue | 117 PSI | Pistols with polymer slides (e.g., Tokyo Marui, KSC) | From 15°C upwards |
| VAPOR™ Green | 145 PSI | Universal use; metal slides and standard replicas | From 10°C upwards |
| VAPOR™ Red | 188 PSI | High-performance GBB replicas with reinforced internals | From 5°C upwards |
| VAPOR™ Black | 217 PSI | Ultra-high power gas rifles; ideal for extreme winter | From 0°C upwards |
Pro Maintenance Tips
Pure power for the cold months: This 188 PSI VAPOR Red is your secret weapon when temperatures plummet in late autumn and winter. While normal Green Gas "faints" and leaks due to the cold, this beast will cycle your metal slide with aggressive, snappy action. But beware: absolutely do not use it on replicas with plastic slides or on unreinforced low-end GBBs. If you think about using it in mid-August under the scorching sun... prepare to pick up the pieces of your tappet plate! This gas is designed for prepared mechanics and harsh climates.
Maintenance for a true operator: As this is a completely silicone-free gas, your accuracy will be surgical because the hop-up bucking will remain perfectly dry and provide incredible grip on the BB. However, this means the replica will not self-lubricate when firing! Always remember, after each game, to disassemble the weapon and manually apply a thin layer of silicone oil to the slide rails, the nozzle's o-ring, and the magazine's output valves to prevent the seals from drying out and cracking.
