I bought these for my G&G MP5A5, I never had any feedimg issues with them but I did have to put electrical tape around the top of them otherwise they wobbled too much, even though I did this I still lost a few of them when running around, I would go to fire my gun an not have a mag in it anymore, which to be honest was quite annoying, but then again wasn't a big deal as I had 10 and they were cheap as chips, considering the low ammo capabilities of these they were not as useless as you would think, I just learnt not to fire when unnecessary, I was also mainly using these when I had DMR'd my mp5 (why not seems like a fun idea right?) So the low capacity wasnt a big problem, they are made entirely of a matt plastic, but did seem pretty durable, i never broke any of them, just lost them.

Love these magazines! they fit perfectly into my jg mp5 a4 with no more wobble than any other magazines i have tried in it. Although they are plastic they are a very strong plastic that doesnt look like it is going to fail on you/me. the colour is a dull black so not shiny in the slightest. the magazines i have found they hold 31 rounds but you only get 27 fired because the spring can only push 28 up and then 4 fall out when you change magazines. i have had no feed problems and i have put hundreds of rounds through each of them just the odd squirt of silicone oil down the feeder and it will be fine. overall great price, good quality and one hell of a good buy.
