For: Echo 1 360rd Fast MK36/G36 High Capacity AEG MagazineProduct Information:
I bought one of these to use with my Ares G36. It worked for a grand total of ONE game before something inside it broke, and now it doesn't wind anymore. That means it probably lasted for one or two fills.
Seems durable enough
Fits into Ares mag well
Mine broke after one game
$21 is a bit much for something you can only use once
Drawstring for winding is tiny and really hard to grab if you have normal sized hands
