Here is the system of the trigger curved hole

The extra rubber is stored like a casual magazine.

More than one year after the first working gun created here at home, I have decided to create an updated version. This new model has improvements such as shot distance (now 5 meters), design and rubber storage system.

THE MECHANISM:

Since the creation of the original mechanism above, it hasn`t changed a lot but the distance and the strain energy in the rubber must be more powerful to achieve a longer shot length.

THE DESIGN:

My main goal for this new version was to add more realism and details by doing this curved arc around the trigger like normal guns. It didn`t take me so much time to think as I had already thought of it before but I had to think on the system which would attach both sides. The other main function I added to this gun was an extra ammo/rubber storage. It isn`t the most sofisticated and isn`t easy to store but I am sure that in future versions it will be something to improve.

I also hope you check out the video below which shows more or less the power of the gun.

Here is the gun put together

LEGO power functions gun (2016)

It took me some time to approach this. That day I really wanted to try to do something cool but rare with these electrical functions so first I had the idea to create a simple minifig size automatic shooter. It worked well but it wasn´t enough for me. I believed that I could turn that system into a real sized automatic gun. In this picture I used the switch the other way around to build the trigger. For the battery I replaced it from the place that you hold the gun which stands out to be the correct size. Finally, the motor was put below where the rear sight would be.
The problem with it is that it can´t achieve very long distances because it is made for minifigure shooters or guns as the system is the mini blaster or ´multi` blaster.
In the future I could try other types of weapons such as mini guns or other bigger models which suit the blaster design and function better.
