Greetings gunfighters!  I'm Terror and I'm new around these parts.  A little background which you can skip if you please, my primary is a KWA CQR MOD2, my secondary is a KWA M1911 MK IV, and my tertiary is a full size KWA USP, and my entire team runs KWA guns exclusively.  I really like KWA's guns, even though they and parts for them are rather hard to come by.  This brings me to my point.  

My 1911 is by far my favorite gas gun that I have used so far, and since the mags are so hard to come by, I only have three.  But one of my mags has a major malfunction.  When I attempt to fill it, gas blows straight out the nozzle.  It does not hold any gas what-so-ever.

Here is a video of the problem.



I gave this mag to my local shop here in SoCal, which the owner has told me many times that he has a special relationship with KWA, so that they would bring the mag directly to KWA to have it repaired.  After about three months without my mag, I called up the shop and raised hell.  It seems that my mag never even left the shop, so I took it back and now I come to the community for help.

First, welcome to the KWA Forums Terror!  Looks to me like the release valve is sticking.  There are several things to try but they may require a valve key.  I would start by putting a drop of silicone oil in the valve and working that in.  It might solve the problem.  If you have a valve key, take out the valve, lube it and re-install it.  Then test to see if the issue resolves.  If all else fails you can simply put in a new valve. They are not expensive and can be found in the KWA Pro Shop.  If you are not comfortable with that, send the mag to KWA foe repair.  They will guaranty the fix for 45 days!  Hope this helps.

Welcome to KWA gas gun magazines -- and O-rings.  As noted this is a sticking release valve, perhaps with debris in the valve area or a damaged O-ring.  For me a disassembly, cleaning and lubrication has fixed my M1911 Mark-series magazines.  If the O-rings are damaged there's a series of good threads on replacements.  While the magazine is disassembled ensure the gas expansion tube (131) is tightly pressed into the magazine base.

Anyone who can spell "tertiary" and use it in correct context should have no problems maintaining these magazines. :)

Thank you for the reply, gentlemen.  gcw360, I have tried lubing the valves, and that produced no effect.  I do not have a valve key, but since on one drunken rampage I decided to try to get the valve out with a regular screwdriver, I seem to have damaged the valve.  Unless I can somehow successfully file down the marred edges that I damaged, I will definitely need a new valve. The Pro Shop seems to be out of stock on them at the moment, but Evike seems to have parts that might be acceptable.  Any advice on non-KWA parts?  

Also, where can I find the correct tool to properly and safely remove the valve?

Airsoft Atlanta has some. http://www.airsoftat...ies-p/99010.htm

Here's the tool you need to remove the valves: http://www.evike.com...57faceed706effb

You can also call the KWA pro shop and ask if they have any in stock because sometimes the online site isn't always updated. KWA's office number is 626-581-1777, open mon-fri 8:30 am to 5:30 pm.

Ahhh, yes, the drunken airsoft technician rage... we've all been there, or known people who've been there. Definitely invest in a valve tool, since there really isn't any other easy way to do it. I'd recommend getting the valve out and checking the o-rings then giving them a nice coating of silicone, and if they're damaged then find some replacements. You could just buy another valve too, which would probably be easier since you seem to have been a tad rough on the current one :P
