These mags while quite good mid cap mags even though they are plastic have several major issues.
the mags have some sort of plastic rattling sound when shaken and full, I’m not sure if its just a factory default on mine or if its in all of them but it takes away some of the reason to get a mid cap because it rattles like a high cap. also the last 4 or 5 rounds will never fire that is if you can get it full, after maybe 70 or 80 bb's it becomes incredibly difficult to add more and to get the 90 that it says fits in you have to use some force on the speed loader and once it is full u will end up spraying several rounds on the ground around you when you try to keep on loading. Also the disclaimer needs a correction, these mags will not fit into any JG mp5 gun i have a JG MP5 SD5, which is not in the series listed in the disclaimer and the mags simply sit in the well for a couple of seconds and then fall out failing to feed a single BB. I compared it to the full metal 250 round high cap shipped with the gun and if you set the plastic one on top and look at the feeding end this Mag is noticeably smaller preventing it from locking into place. they seem like a pretty good buy but not if you have any sort of JG MP5.
Probably won’t be hard to pawn off to my friends with MP5s
Hold more than advertized
Won’t fit into any JG MP5 series gun
Never feeds last 4 to 5 bb’s
Extremely hard to fill up and you will lose several bb’s spraying all around once you really fill it up.
