Doesn’t everyone have this set in the garage?

and the SAE one too?

Yes, I think it is the o-ring inside the magazine. Reconditioning can fix it, and that has worked for me. Another method is to replace the original o-ring with a thicker diameter o-ring. You would still have to lube of the new o-ring, but that has also solved my problems.

The last method I talked about earlier is to use gasket sealer. This is a last resort method. I usually do this to the KA v1 mags, because those are just a pain in the ass to fix it any other way. This will definitely fix any leaking problems, but it is a mess to take the magazine apart once applied.

I would also recommend getting sets of gaskets in metric and standard from amazon. ~$30 for 800 gaskets. I personally think it is a must if you have a lot of GBBs. Because these things WILL eventually fail, just a matter of time. Metric Set Standard Set

I have used them for pistol mags, and I have used a few for the nozzles.
