All in all, I'd have to recommend against it... When it works, it works great. But, there's not really any way to tell if it's going to work in the middle of a game or not, you just have to hope you get lucky. It may feed fine when chrono'ing before the game, and then not feed halfway through the game, for no apparent reason. I'd recommend just getting some decent G36 mags. ("decent" does NOT include STAR. Their midcaps are crap.)
