Ultra gas in a new skirmish friendly, portable 270ml can! Designed between Abbey Supply Co and Land Warrior Airsoft to address a problem we had seen in recent years with Airsoft gas. We found that when pistols cool down they excessive lubricate the hop unit within the pistol or rifle. When this excess builds up your hop stops working and performance drops massively. This gas prevents this by having the lubricant removed. This doesn't mean your pistol will be damaged in anyway so long as you follow your regular maintenance (as you all do anyway). It does mean you will get better performance all round: Higher FPS than standard Predator Gas (+10-20fps) More stable hop up Less prone to cold and damp weather.
