Not commenting on the airsoft wannabes, but they do make some interesting toys. I try to pick up many of the variations, for recognition and safety understanding. Ran across the R2BS at a gunshow this past weekend and bought a couple, I'll cut them open this weekend and see if we can get a couple of training pieces that can be passed around. In the meantime I thought members might enjoy both the factory video and some of the pre-surgery Xrays.
