“This MP5 impressed me straight out of the box, it came in a nice and simple carry bag, it looks pretty accurate to the real thing and fells nice simply to hold. Its satisfying to use the charging handle even if its just for show, and the blowback when firing is nice... However... I've had more than a few issues with gel balls failing to feed correctly, leading to minor jams, gel balls exploding in the barrel, gel balls straight up falling out of the barrel, and gel balls escaping the mag and rolling around freely in the empty space between the gun and the mag. The MP5 also has a minor accuracy issue, it feels like no matter how steady I hold the gun, gel balls will sometimes find themselves going way off corse and traveling straight to narnia instead of their intended target. These issues have annoyingly lead to many wasted gel balls and quite a few losses in battles against friends. I love how the MP5 looks and feels, but nothing's worse than having your gun jam while trying to get the drop on someone. It feels wrong to say this, but if this is a widespread issue with this model, I do not recommend using this in battles.
Another issue, when mine got shipped, it was incorrectly shipped without the drum magazine, though hopefully this was just a one off thing and not something that happens regularly...”
