Introduction: Demon Machine Gun

The Demon is my full auto, large and in charge gun! Unfortunatly it is known as the Demon because it is cursed. This my third version of this gun and the smallest of any version previously made. It has a range of the 5 feet and is powered by two motors and two rubberbands. This gun is still being perfected so unfortunatly no instructions....yet. I will produce a better and more powerful Demon. Until then enjoy these pictures.

Well I'd hate to say this, but I won't be making any instructions for this. I can say I used the mechanism from the rapid ball juggler and that barrel is all for show. Realistically this gun wasn't very good, although I have had the urge to try another one.
So I'm sorry I can't, I can help you figure out how the mechanism worked if you need that but I can't rebuild it unfortunately.

Well, full auto is one of those mechanisms that is still highly conceptual. Trying to balance the range to rate of fire to power source is what makes full auto hard to build.

I used the mechanism in this ible' modified to work sideways

However I would try (if you have the pieces) the auto rifle by kinetic or a mechanism similar to KILLERK's Dam just modified to be slower.

Good Luck!

i would like to throw out this theory, the reason it only gets 5 feet is because the snowflake and rod barrel where the bullet comes out, those type of barrels have insane amounts of friction (trust me i kno)...so use something like the front of my removable mag assault rifle, just make it longer to make it look decent

AGAIN ITS JUST A THEORY, U DONT NEED TO BELIEVE ME
-caps were on purpose- =P

Just so you know the barrel is fake. =) It was added for appeal. It actually shoot from a white connector just below it.

The yellow connector. My bad, I thought it was a white one.

Honestly, the gun is ugly, which is what makes it cool. Keep up the good work!
