Ok, I found this while searching the web trying to find that tech taget knock off. I can't really date it because the web page seems to be active still, but there is a reference to the side-scrolling action game
Strider. Also pictures of certain types of ammo certainly have a nerf-like resemblance. It appears the guns are from different times in history. Some of the guns appear to look real because of black/silver paint.A law was passed in 1992 that says toy guns are required to have an orange plug or be entirely brightly colored to signify them as toys. 1992 is only a year after nerf started making toy guns, and he mentions once in the rocket launching weapon there is a part where he states "for serious dart gun warriors....", could this be the beginning of nerf fighting? Here's the link
