Western Arms Gun Problem

[tdow]

I just bought a Western Arms MEU SOC late model as my first airsoft.

I've been having a problem with it not retaining its gas. I'm using 1234A in it. It will sometimes make it through an entire mag, but usually it will last a few rounds then just kind of poop out on me.

The manual doesn't help me much since I don't read kanji so any help would be greatly appreciated.

Where is the gas escaping from? Have you oiled the pistol at all? Try getting a silicone spray (do not use regular oils in airsofts) and spray the internars of the slide. Also a drop of silicone oil in the magazine, at the hole from where the gas is shot out to the slide, may help.

Correct me if I am wrong, but is'nt 1234A red gas? And if so it is too strong for most stock airsoft guns. Try regular green gas and see if that does not correct the issue.

Use red gas only if your weapon has been upgraded with heavier seals.

"Red Gas" is mainly a myth, while there are more powerful gasses than green, most gas sold as Red is just rebadged HFC22. There are a few gasses that are made for airsoft that are more powerful, but I only know of one place in the US that sells it, and they wouldn't let you run it in a WA. Western Arms guns, and all Japanese-manufactured guns, should be fed HFC 134A in stock form. Green gas (HFC22) or propane are for upgraded Japanese, or Taiwan/HK manufactured gas pistols. Japanese guns are designed to fire at lower velocities as mandated by Japanese law, so they are designed to work only as well as they need to.

I use to work on those pistols. Typically the single stack mags will handle green gas but their relibility goes way down. With the single stacks especially with the SCW2 version gas systems your better off sticking with 134A. The only guns that will handle the hotter guns are the double stack. I've got a couple that shoot at 360-380 with some mods i've done. Oh and i'm using .20 excels

this might be the problem, when you go thru an entire magazine rapidly, this causes the gas inside the magazine to expand( i think its expand or something, but basically you will notice that the magazine becomes very cold and this greatly reduces the amount of shots you will get per magazine, so what you have to do is either fire slower, or let the magazine return to a normal tempurature (room tempt) before you recharge it and use it again.

Cold weather influences gas guns GREATLY. Rapid fire also cools the gas so it doesn't expand as fast*. Also if your gun has a metal slide your gas might not be powerful enough to get out a full magazine with the extra weight.

* Compressed gas is naturally cold, and expands when gas is released from whatever is containing it, when it expands it retains overall pressure. If a gun is fired rapidly and requires a large ammount of gas for each cycle, the gas can't expand fast enough to equalize the pressure. This ammounts to using the cold unexpanded gas. Normally the gas would warm and move to the top of the mag to be released into the gun when fired. But since the gas is cold it stays low and alot more is required to be as powerful as the warm gas. You may notice moisture in the form of water alongside your mag, which means the entire mag is cold and unable to produce decent power. - I hope this helped.
