Unknown nerf guns

I found some unknown nerf guns and some of them can be found in the wii nerf games.and i only found 4 of them.The one above is named, Semperfire RF-200.

Next up is Crusher O.B.B (one.ball.blaster).

This is named Bullsharc GL-8.

Lastly,it's Cerberus cs-12.

This is what i found on google,the rest of them had took a step forward and evolved.I would find time to post up some examples :)
