KWA M93R Leaky Mag
« on: November 11, 2009, 11:27:10 AM »
I'm loving my M93R. The amount of gas it uses, which a lot of people don't like, doesn't really bother me as I can still get the whole mag out. However, the magazine has an audible leak in the fill valve, and I'm not really sure how to fix it.

I poked around with Google, and found this. It looks like a good guide, but it's not designed for this gun. I couldn't figure out how to take apart my magazine. ~.~

How To Fix Leaks

Leaks in these mags are most likely to occur because your chamber o-ring isn't making a good seal. If the leak is bad enough, you'll actually be able to hear it right after a fill. The mag in the picture had an audible leak when I first got it, so I did the thread mod, which works like this.

Remove the chamber screw

Seperate the halves of the chamber

Remove o-ring and wrap thread around where the o-ring goes. This should cause the o-ring to stand further out, creating a better seal. While you have it open, a little silicone lube or gasket conditioner is a good idea. Hint: the thread will soak up the lube, so go ahead and put some lube on the thread so that it feeds lube to the o-ring instead of stealing it.

It looks like it would work, if I could get the magazine apart. I can't find anything on the subject that is specific to my gun (KWA M93R NS2). Help and experience is appreciated. How do I get the mag taken apart? Will the above-mentioned fix work? Are there any other fixes I can do, possibly without taking anything apart?

I'm not familiar w/ the KWA M93R Magazines, but if they're anything like most magazines, there will be rivets holding the feeding assembly in and the mag plate in. take out the rivets holding in the mag plate and you should see the valve, which has a slot in it for a screw. Unless you can already see it... in which case you just go straight to unscrewing it. After you make sure it's out of gas.

no string, that's just, well, stupid

use engine grease, nice and thick all temperature lithuim based engine grease

available at walmart for 1.82!

or rtv3 sealent, or silicone sealent, anything that forms and seals into a gasket will work just fine

thread, no
