A forty round magazine is a Nerf High-Impact Round magazine that was released in 2016.

It comes packaged with the Khaos MXVI-4000 and can be purchased through Amazon, but otherwise is not sold separately in stores.


As its name suggests, the forty round magazine holds up to forty High-Impact Rounds at a time, in four columns of ten. 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. Each of the four spring-assisted followers can be pushed all the way down and locked into place, to ease in reloading the magazine.

At this time, the magazine works exclusively with the Khaos MXVI-4000, and the Khaos cannot accept any of the smaller magazines.

These magazines can be speed-loaded by unloading twelve round magazines into each ten round area of the magazine for quicker reloading.


  • The magazine can actually hold forty-four to forty-five High-Impact Rounds by opening the top of the magazine, putting one extra High-Impact Round on the top of each column, and then closing the top. It is also possible to squeeze a fifth in place.[1]
