You know the small black o ring that sits inside the mag fill valve so when you fill the mags the gas doesn't start spewing everywhere and you get a really crappy fill of gas?  Well I have lost those on 3 of the 4 Kwa MP7 mags that I own and I would to tell of a very simple and effective solution to this.  Also this can be done to any Kwa gbb mag that you have lost the O ring to =D

So what you do is buy some plumbers tape and then cut about an inch and a half of it and twist it to make a stick.  Then carefully using a small hex key push it into the outside area of the mag fill valve where the black O ring use to be.  Then after you have successfully pushed in all of the plumbers tape, put a drop of silicon oil on top and do a test fill and press hard (just by filling the mag will do this) to push the plumbers tape down all the way and immediately you should see that there is no more leaks!  I will add pictures soon =)

Dito that. I have an MP9 mag and two M18 mags to try this on.

Why does KWA just put an O-ring in the valves with nothing to keep them in there?

The catch is that shipping is probably 20 dollars ;_;

edit: Just noticed the double post, if someone could delete that please?

Yea I took my leaky MP9 mag into my local shop and dude actually used like the, I dont want to say liquid, but like some plumbers thread sealant putty stuff in the charging valve. Just a dallop but it worked like a charm. I imagine the tape method would be a bit cleaner tho, good call

So i'm curious. When you lose the fill valve o-ring how much of a mags worth of bbs do you get on a charge of gas? Because I just found this thread and checked the fill valve for my kmp9 and found no o-ring there-I get about half a mag worth of bbs before it sputters and dies, when I fill it propane shoots out after about a second of filling.

Well, this is a 2 year old thread but, because it's a relevant question, I'll keep it open.  The short answer is...it depends.  I have been able to get close to a full mag in a m19 magazine without the o-ring present.  But you loose a lot of GG or propane.  I suppose if you are getting half a mag with the you MP9 that's the answer to you question.  O-rings are an easy fix and readily available.  Pick some up and you won't need to worry about partially filled mags anymore.

To add on to what gcw said, I only have the o-ring in one of my mp7 mags atm and one has a moon dog industries o-ring, and im able to get about 1.5 mags without the ring and 2 or more with it. So if you can find spares, buy them, they are well worth it.
