Just to get some more information out there, I was an R&D consultant for AR500 for about a year. There exists one set of this, and it is NOT ballistically rated. It lacks the proper components to prevent backface deformation, which is one of the factors involved in rating/certifying armor. There are plenty of materials that stop a round from penetrating, but if they exceed a certain amount of deformation on the backside, it can still pose significant injury risk to the user. There is a reason ceramic and UHMWPE plates are as thick as they are, and almost half of the thickness (at least with UHMWPE) is to mitigate backface deformation.
The helmet is incredibly hard to see out of, not surprisingly.
If you want something like this, Ryan Flowers at Galac-Tac (the original main designer) sells non ballistic versions.
