Great green gas from ASG with silicone. The 135 psi pressure works perfectly in warmer days for pistols with metal slides. In colder days, it can be used for pistols with plastic slides like Tokyo Marui.

Good gas for colder weather. For me, it works in the APP01. At around 0 degrees, you could shoot without any issues or mag siphoning. I recommend it.

Good, strong gas. On colder days (10°C) it works well. The only downside in my opinion is the metal valve, which can damage the magazine's seal. Ideal for pistols with a metal slide where higher power is very useful, especially for dynamic CQB shooting. My CZ P09 works excellently on this gas (especially in temperatures of 15-20°C), power also increases by about 0.2 J compared to standard gases from other companies. Highly recommended!

Very efficient gas for cold weather easily lasts for 2 or 3 magazines noticeable increase in FPS with this gas perfectly suited for replicas with a metal slide I'm really glad that you can get a high-pressure product without silicone - that's exactly what I was looking for. If you know how to properly take care of the seals in magazines, such a dry gas is exactly what you want - no unnecessary silicone in the hop-up and inner barrel!

This is an interesting option for more advanced users, especially for the increasingly popular gas main replicas. It is a dry gas, so you need to remember to lubricate the seals, but on the other hand, it does not negatively affect dirt buildup in the replica or hop-up performance. You should also keep in mind the increase in power compared to the "standard" Ultraair gas at the level of 5-10%, depending on the replica. Unfortunately, the composition is also the main drawback of this gas, as it contains 15% HFC-32 (Difluoromethane), which transforms into very toxic hydrogen fluoride in the atmosphere.

I bought this gas because of its pressure, so my replica wouldn't break on hot days. The gas was tested on a KP-13 replica if anyone wants to know. Surprisingly, in my opinion, it's more efficient than the popular smart gas. The gas contains silicone, which lubricates the inside, although when it comes to silicone in gases, experts are divided on whether to use gases that contain it... The slide works like a dream. I can definitely recommend it for hot days :)

The gas works fine at 16-18°C; above that, it's better to refill with propane. However, for this price, I prefer Nimrod, it seems to last longer for me. Here, the steel nozzle is a plus.

Super gas for summer, I've been using it for a very long time in GBBR and GBB replicas and I've never had any problems. I also recommend other gases from this manufacturer—they are worth their price, and there are often promotions at the Militaria store. Another big plus is the fast delivery :)

Very good and strong gas for cold weather. Unfortunately, polymer slides can be damaged when using it. I do not recommend it for TM replicas. Every other replica accepts it without any problem.

Performance and results, just like the orange and green gas from this product line, are at the highest level; of course, the red one is better for lower temperatures :-) I highly recommend it!

After being impressed with the orange gas from this series, I tested this green one and I can confidently say that I'll stick with it (if we're talking about a temperature range of 20°C and above). The GBB pistol works fabulously, the slide moves quickly and dynamically, and there are no jams or cooldowns during intense CQB skirmishes for over 2.5 hours. Additionally, it's very efficient (when rapid firing, 2.5 magazines of 25 BBs on a single charge). When it comes to standard gas in standard temperature ranges, others don't stand a chance—and I’ve tested quite a few. Highly recommended!

Very good gas, it is strong and efficient (enough for 2-3 magazines of 25 BBs each), ideal for pistols with a metal slide where higher power is very useful, especially for dynamic CQB shooting. My CZ P09 works excellently on this gas (especially in temperatures of 15-20°C), power also increases by about 0.2 J compared to standard gases from other companies. Highly recommended!
