Probably Zam's scope. Remember when Jango's lowerd and his rocket fired off? I think it is a targeting computor bit in the helmet much like the x-wing had when Luke looked through it. But am i entirely sure? No. But i think thats the way to go. I don't think there are pics or angles to where you see it. it be cool to do like some kind of LED thing with a grid look when it lowers it lights up with this cool grid look. I dunno lol hopefully this somewhat helped.
