RBG: Halo Plasma Rifle

A knex RBG that looks and shoots like a Halo Plasma Rifle.
After two months of testing, building, and modifying, I finally made an semi-automatic and automatic rubber band gun. No instructuable yet, but here is a slide show. It uses the same firing mechanism as my plasma pistol, but two of them that take turns firing and resetting the trigger. However, this gun does not have a trigger.

    Really. Most of the time was spent on designing an automatic firing mechanism, about a week for the exterior, and a week of testing.
