||Good magazine, but has many fatal flaws. I ordered about three at a time (to make four, with my pistol order)
The "rubber pad" on the bottom is a big chunk of metal, Which is actually good since i've somehow been plagued by bending the base plate on the normal OEM version. This version has a big, thick chunk there, so it's much easier to not break.
The mag is sturdy and should not break
The magazine followers, like always, are complete trash. If you accidentally let it flick up to the top, it's about a 1/5 chance it will break. I always cringe whenever i do it, and i've resorted to filling from the top JUST to make sure it wouldnt have the chance to flick back up. Come one WE, Replace that thing with an ALUMINUM follower!
The fill valves on two out of three of these either came bent, or came clogged, since they both are skewed a bit to either side and leak gas whenever i try to fill them. It's a rare sight for me to actually get one of these magazines to hold enough gas for the full 12 shots. I also live somewhere quite hot, so temp isnt the issue. I have to jam my propane+adapter into the fill valve at a certain angle at more pressure than should be neccesary just to make sure i'm not icing my fingers with the compressed gas. I'm really upset about that, but i'll order some replacement valves and hope for the best.
Like above reviews say, These (on a good charge, not crap like my mags) can hold about a full mag and a half worth of gas.
I'm really upset with evike / WE for sending me faulty mags, and i'm upset that WE does not have a bit more quality with their magazines. It's strange to say that because their actual guns are pretty much top notch.
Step it up, guys!
