The Combine Pulse Rifle. I don't know who originally came up with this design, but I added stuff to it and made it my own. But if someone knows who has rights to it, please let me know.
Place the revolver and hammer in the ends of one of the binoculars and put another bino' on the other end facing the same way. Glue works good. Mine is glued so I couldn't take it apart. This is the 2-3 bino' part: I cut one in half and put the 2 sides on the indside of the gun and to make another part of the gun, once again: glue.
Then set the goggles on the side to emulate the magizine holder on the gun and Voila! The Pulse Rifle! And some black paint too. There you go Nathan, hope it helps, and anyone else that wondered how to make one!
Cool! I'm not sure, but I think that Keith Goldman has quite a few guns with a similar design. Hope that helps! His brickshelf account is kgoldman...he's here too, but I'm not sure of his username.
