Spare Gas Magazine for GHK AKM Series Airsoft GBB

"Update on how to load these to those who need it.
How I load these is I use an old fashioned speed loader the the GHK AK mag loader adapter attached, it doesn’t fit normally so I shaved down the tube, made a 20 bb mark, filled it up to that line, and used the speed loader to load it. Hope this helps!

"Sturdy mags
Pros:
Hefty
Mine were pre charged
Mine did not leak
Fit great
Works as expected

Cons:
Hard to first load, load em up by hand and keep em charged for a bit,weakens spring to the point you can use speedloader, broke 2.

"Works as expected. A replacement mag for what comes with your GHK AK GBB

"Great mag, functions near flawlessly. Used them for a couple games now. Very hardy, but heavy as is any gas magazine. The charge valve is in an extremely inconvenient place if you wanted HPA tap it. Its located at the same level as the magazine release when loaded.

Pros: Efficient
Functions well
No leaks
Sturdy metal

Cons: Valve placement
Heavier than other GBB mags
Doesnt come charged with gas so seal may be bad

"All of the mags I have are leaking gas after only one use to test fire them. I tried replacing all of the gas tube O-rings were the leaks were coming from and the seal would only ever last for 1 game of airsoft. I even tried gasket sealer the last time I changed them and that still didn't help somehow.

Pros: Strong, heavy metal construction
Fits solidly in the rifle

Cons: Gas leaks
Hard to load, even with speed loader adapter
