Relax, as long as the mag is metal and pretty hefty there shouldn't be much risk of destroying it. Sometimes it takes a firm wack to take the pin out. Since its a roll pin it shouldn't have a knurled edge but you could try hammering from the other side. Sometimes when hammering a pin out they have to be hammered from a specific side.

Perhaps you could try to leave the mag in a hot car (no gas of course) and let the mag get nice and hot. Then maybe just maybe the metal in the mag will expand and allow the pin to come out a little easier. Just an idea.

Same problem, can't seem to find replacements for these fill valve o-rings :(

Spray's propane everywhere? TM mags typically spew gas when filling. It is normal. Some mags don't. Or do you mean it leaks out of your mags from the fill valve after you pull the propane tank off?

I got orings from a refillable lighter and used them on the fill valve(on the outside of the valve) to stop the gas from leaking while filling, or you could try a different tip that seats better from one of those butane cans.

Do you apply it, let it dry, put the seals onto, apply more and dry? Or do you work with everything while it's still in its goopy blue state? Cheers

apply it and put your mag back together again, so the gasket sealer fills the voids. Wipe any excess off, gas the mag and allow the sealer to dry overnight.

Thanks for the response, for a we scar gbb mag- do I apply this on the silver backplate of the mag that screws onto the mag? Or on the mag itself where the large rectangular o-ring is. If anybody has any idea I'd really appreciate it :)

Why is this not stickied?!

I am going to fix some mags using gasket maker, and I just referenced this to make sure I'd be doing it correctly.

Hello everyone,

I have a WE glock mag that is leaking from the output valve. I forgot I already had the mag fully gassed and went to fill it today thinking it was empty. Something must have blown because now the mag leaks like crazy from the output valve.

Ive removed the valve and the O-rings are intact and look perfect. Yet the mag still leaks like crazy. Does anyone have any suggestions on how to fix it? I am soaking it silicone oil right now so hopefully that will work.

Thank you kindly!

Added bit of gasket maker and my g36 mag is gtg! Thanks

Use grease. Not silie oil, but thick grease.

I am soaking it in oil to see if that works. Just to be clear, Im refering to the valve that releases gas into the blow back unit. The strange thing is that the o rings look perfectly fine.

oiled/greased o-ring makes better seals though :)

Quick question for you guys. I have some hi capa mags, and when I go to fill the mags, they like to spew a lot of gas at the fill valve. As a result, I only get enough gas for about 10 shots before empty. I know a solution is to get some new fill valves, but is there a way to fix them?

Could be the nozzle on your propane adapter is flared out and not really good anymore?
