semi-auto/full-auto knex rubberband launcher Answered
a semi auto rubberband launcher. really a semi-auto and a by un connecting 2 peaces you can quickly switch to full-auto. uses a new triger system that i thought up. lets the gears turn only when you push the triger. working on instructions. i also made duel rpg pistols useing the same firing system. i will put those in the instructions.
