Poseidon 50 Round Magazine for Glock AAP01 WE Galaxy EMG BLU Orion Gas Blowback Airsoft Pistols
(Color: Purple)

"First time owning an extended gas mag, no major issues. OTHER than the fact that the website LIES TO YOU!!!! It can only hold 44 rounds NOT 50!! and it leaks a little from the seam on the top but the valve doesn't leak at all. When I say a little I mean like it will take several weeks for a full mag to go empty. mine had enough gas last night to keep the valve tight but this morning it finally emptied from about 2 weeks ago when I went to airsoft and used it, I was even able to dry fire it a few times in-between me using it and when it went empty. Docking one point for the False advertising and the Very Small leak but other than that its a solid mag!

"I am generally not happy with this product when its new. When I first gassed it up it would hold for maybe 5 sec then the output valve would open and the gas would release. I then took the output valve and greased the orings up, the mag then held gas for 30min to a hour then randomly expel gas. I happen to have a upgraded output valve laying around an tried that, all problems were gone and put the mag in my orion and worked perfectly. So when purchasing this product you will most likely need to also be looking for output valves.
