Green Gas 50 BB Magazine for M4/M16 GBBR Replicas

When the magazine arrived, I immediately filled it up with gas to see if everything was ok, unfortunately not, because it leaks, luckily I managed to fix the problem, but for 60€ I don't think you would expect that out of the box you have to fix it.

These mags, the so called MC-20 (King Arms, Western Arms, G&P, etc. compatible mags), are just colossally awful. I buy them because they are the only "WA" (Western Arms) gas system compatible mags out there. These magazines arrive pre-filled with green gas, which is not by chance; leaving them empty for a day or two leads to leaks, so don't forget to store them filled. I experienced a leak with a Golden Eagle (MC6596M) stock magazine (which is the exact same model) after neglecting to refill it with green gas for just one day, but it's a mistake on my part. Leaks typically arise from either the bottom seal or where the upper (output) valve body meets the magazine shell, about three fingers width below the top of the magazine. The output valve itself is usually reliable, so leaks most often occurring at these two points. Repairing these magazines is a daunting task, as finding suitable replacement seals is difficult, and standard O-rings are incompatible due to the original seals' rectangular shape. I was able to seal the bottom using the original O-ring and a significant amount of black RTV silicone, but was unsuccessful in sealing the upper part due to the absence of the required rectangular O-ring. Even when the original O-ring is undamaged, achieving a seal with RTV silicone is challenging and I ended up breaking my original O-ring due to the tight fit. Unfortunately, I purchased two additional magazines and one began leaking shortly after I emptied it (refill happened in less than 1-5 minutes of being gas-free). I managed to temporarily fix it by slowly and carefully refilling it with gas, but its longevity remains uncertain. It's imperative that Gunfire reconsiders their pricing for these mags, as charging 60 euros for a product that may only function once is unreasonable. I suggest, if you do not want to reconsider your price to ship these mags with spare O-rings and a guide for servicing. 60 euros is half the price of some replicas....

Hi would like to know if these chargers would be compatible for the mtr 16 from Marui
