If I may add to this thread.

Personally, I don't completely wipe the side of the mags clean of the oozing gasket maker. I smear it onto the seam to give a little more sealing, just in case. Not too thick though, because if it's too thick, the mags won't fit properly in it's casing.

Also, I use O-ring grease (available at any pool supply store) on the valve o-rings before screwing them in, keeps them oiled up much longer then low weight silicon oil.

Thanks guy's

I used the black gasket maker without the o-ring on one of my kc-02 mag for a test.
Seem to work for now. I filled the mag and no leaks yet. Will wait a couple of hours then do my others 5 mags.

Where do you get a valve key? I can use a flathead to get the fill valves out but the knocker valves are a different story.

really Sam?

Hi. Sorry for the necropost!

Wanted to ask whether this repair you've written this great tutorial for (using your latest black gasket maker technique) results in a permanent fix from the version 1 mags? I as because I'm trying to work out whether I should take up a deal on getting used version 1 mags that "have no leaks" at $30 each or whether to spend the extra and get the version 2 mags.

Cheers!

Get the generation 2 mags. No question about it, they're much better.

Thanks Wedge, v2 mags it is then!

I liked the improved gen. 2 mags so much, I bought the mod kits to convert all my first gen. mags!

There is a kit to convert Gen1s to Gen2s? How does it work?

I haven't been keeping up, but my WE is closed bolt still and I intend to keep it that way. Are the V2s compatible with closed bolt systems?

I believe all you have to do is put the top feed lip part onto the v2 core and your fine. I rmbr playing at sgt and some dude said he had v2 CB mags

Thanks!

Don't see why not.

The mod kit comes with a new core - one with a much improved gas seal. If I recall, the kit sells for about $20, and it includes just six parts. Everthing else comes from the donor mag. You might also be interested in a mod kit if you've damaged a gen. 2 mag (although, they're plenty tough).
