The pellets of the X-Shot Hyper Gel Assualt Rifle are so-called hyper gel pellets. These gel pellets are typically around 7 to 8 millimetres in diameter, which is the standard for gel blaster ammunition. The pellets are dehydrated and must be hydrated with water before use, causing them to swell to their full size. These pellets are non-toxic, environmentally friendly and do not stain.
