Ok, heres what i did for the hasbro scope.I used my dremel and cut off the speaker box/power cylinder section,Cut some small strips from a for sale sign,heat bent them to fit the inner curve of the scope and glued them in with GOOP.I then sat and globbed on bondo,having sanded it smooth to the shape.I also had cut small rectangles and built up the sides of the mounting areas.For the front lens area, i used a nerf dart suction cup,glued with goop,then i cut off the suction cup leaving the base,followed by drilling out the middle of it. More to come,lol.
