This is my first Fully automatic lego gun ever. I always wanted to make one of these because it shoots 30 rounds in less than 3 secs.The mechanism is very easy but the body is very complex:
there's a motor, connected to the battery box (above the trigger) that pulls a string up. this string is attached to a technic piece that is inserted in the magazine. when I pull the trigger the motor will pull this technic piece that will push the bullets up until they "go out of the magazine" and they are catapulted for the rubber band that is hooked in the front. I made this gun following the book Badass Lego Guns instructions. please enjoy this images, rate and comment.
Thanks for watching this gun.
