A forty round magazine is a Nerf high-impact round magazine that was released in 2016.

It comes packaged with the Khaos MXVI-4000. It cannot be purchased separately in stores.


As its name suggests, the forty round magazine holds up to forty high-impact rounds at a time. It is loaded from the top and is opened by a door that will hold the rounds ready to fire when a switch at the bottom is flipped up.

At this time, the magazine works exclusively with the Rival Khaos MXVI-4000, and the Khaos cannot accept any of the smaller magazines, such as the one packaged with the Zeus MXV-1200.

These magazines can be reloaded by unloading 10 round magazines into each 10 round area of the magazine for quicker reloading.
