How to Fix Leaking CO2 magazine - ASG Shadow 2

Few weeks ago I started having some troubles with one of my spare CO2 magazines for my ASG CZ shadow 2 Airsoft pistols.
Generally, when I installing a new CO2 bottle, 80% of the gas just leaks through the magazine and I need to Install a new one (where, usually the same thing happens again). This is how I wasted maybe 6-7 bottles, until I decide to take action and see whats wrong with it.
Here I am sharing a quick video how did I fixed it.
All you need is valve key - to remove the valve and silicon grease to lube the O-ring. Unless the ring is damaged and you need to replace it.

Thank you for this. I just had this probmel with my Beretta Umarex magazine. I did what you suggested and it fixed the issue.

Glad it helped:))

One thing I've noticed is that the included o-rings sometimes aren't the right material to handle the low temperature. Swapping them out for higer end ones along with using silicone grease helps alot.

Love to hear that, I will upgrade them eventually thx for the advice 🙌🏻

Great instructional video brother. Lots of people wouldn't bother with this 5 minute fix, and just order an entirely new magazine......... for $45 !! Not cheap, and likely cost more than a real steel mag !

Thanks, hope I help someone tosave few bucks. Would be helpful when all your 3 magazines starts to leak:))

With my gun, it holds the gas, but when you shoot it, no bullets come out, and the gas inside all just comes out at the same time

Hello there, question, how are you satisfied with the pistol so far? And what are you using to protect your Shadow 2, some grease or?

[@yordanyordanov8085]

So far thats one of the best CO2 Airsoft pistol i have seen. Literally I love it, there is only one issue with the spring guide spacer but that is manageable and easy to fix, you can check my other videos on it. I use only silicone spray and silicone grease for all my Airsoft pistols:)

Wrong google account on my response, but that was me, sorry :)

Where did you get that valve key? Also do you know of any sites where I can get replacement O-rings?

[@airsoftsharks]

I got the key In a local store it was pretty hard to find it btw. Really depends where are u from and how long you can wait for o rings try airsoftzone.com or redwolf airsoft or evike.com

Can anyone help me maybe ?
Today i bought an co2 pistol GBB 4.5mm first 3 co2 cartridges worked fine.. but with the number 4, the power behind the shots is low and the blowback does not have enough power to fully come back and cock the hammer for the next shot... i tried installing a new co2 cartridge but the same thing happend again???
Can someone help me?

Hmm I can just speculate but few things are popping in my mind you could check :
1 ) make sure you tighten the CO2 bottle nicely - I had a case where I did not tighten it hard enough, and the bottle was not opened enough, eg the throat of it was 1/3 opened only when inserted.
2) the slide does not cycle close fully, even a few inches can result i lost compression and lost co2 - for that one observe it manually when reloading does it move freely does it close all the way without issue. If you feel something is stopping it you need to disassemble it and investigate what/where is the cause.
3 ) check the magazine manually apply pressure on the valve and see does it release the gas in high pressure via the gasket.
4)Take a look at the trigger mechanism, I am not really familiar with the triggers but it could be something obvious that need a repair/replacement
