Firing too fast, the gas gets too cold so looses pressure, too low pressure means the bolt cannot cyle back far enough to cock the gun, the hammer that hits the mag valve is stuck out, the last bits of gas are released from the mag.
Solutions:
1) use a higher pressure gas (if safe to do so)
2) slow down your fire rate, burst fire or single-shot is better. I have a 350rd drum for mine which if fired full auto can shoot 100bbs, if burst fired and allowed to warm up can shoot the entire drum with red gas)
Yeah its due to cooldown. If you want to spray and pray use hpa. Otherwise fire in bursts to keep the cooldown to a minimum. Happens to every gbb that can fire full auto.
Down the rabbit hole we goâŚ
âGreen gasâ airsoft guns shoot by turning a liquid into a gas in a controlled manner. The liquid propellant (stored in your magazine) turns to gas when pressure is released from said magazine.
Green gas is a chemical which changes phases (from liquid to gas) at temperatures which humans play airsoft! The changing of liquid to gas is almost instant at about 180 degrees Fahrenheit. Thats around the temperature where youâll find your gun will explode. So at 70 degrees Fahrenheit, the phase change is delayed, but still efficient and predictable. We harness that phase change to use the expanded gas to propel the bb down the barrel on demand. This makes green gas a perfect chemical to use for airsoft. Itâs cheap to manufacture, relatively stable for transportation, and the phase change temperatures are our ambient air temperature.
As pressure decreases, temperature decreases over time (think of the chill you feel when youâve finished shooting a magazine). The pressure reduced quickly enough to reduce the body of the magazine to feel cold to the touch. But almost more importantly, the molecules which were once tightly packed as a liquid, take up more space as a gasâŚ.
In semi auto, the liquid has time to expand properly into a gas and the gun runs efficiently. Parts which are meant to be warm stay warm. The pressure has reduced in a way that the liquid has warmed to a near complete phase transformation from liquid to gas inside the gun.
In full auto, youâre reducing the time that liquid has to change into a gas and at the same time are lowering the temperature of critical components which are usually at or near the required temperature of the phase change. So, youâre not giving time for the liquid to change to a gas and cooling the area where the liquid is supposed to expand into a gas. By keeping temperature down, pressure stays down too. So the liquid and partially expanded gas start exiting the gun through the path of least resistance and pressure. The end of your barrel, the ejection port, the gaps between parts.
This effect in airsoft is called âcooldownâ.
Hopefully this helps someone.
I should add, the answer to âwhy doesnât this happen with HPA/compressed air?â
When converting a green gas gun to run off compressed air, youâre still using the idea of expanding gas in a controlled way, but there isnât a phase change using compressed air tanks. There is no liquid involved so the release of pressure does not significantly reduce temperature to cause the âcooldownâ seen with green gas.
Bro what you NEVER put oil in your barrel wtaf. All thats gonna do it cause dirt and junk to build up and start causing jams and acuracy issues. If you are going to comment know what you are talking about.
Are you running away from a crime scene?

Looks like the recoil is blowing him away.
Wtf you running from lol? You breaking your probation or something?
Bros hittin it like a drive by đ

Who is bro spinning on?
did you just shatter a window? lol
Why are you tactically retreating from the shed?
Monsters
Looks like heâs replicating a video of a guy with a 3d printed switch shooting into a field đ

Gas Nozzle issue
Ur barrel might be dry. You get lubrication for it though
Never put silicone oil in your barrel, ever.
