How to Make a Inexpensive and Powerful Nerf Gun




This is my first instructable, so I tried to make it simple.
The purpose of this instructable is to make a cheap Nerf dart gun that carries 25 rounds and shoots faster than an average Nerf gun.
The main idea is to make a marshmallow shooter which I found is the ideal way to make a pressure shooter for the darts since that is how they are made to be launched.
Most of these steps are very malleable and based upon personal preference. However if you want the desired effect that I have intended, then just follow the given measurements and specifications.

Step 1: Materials

Here are all the materials that are necessary for the project. If there is a parenthesis beginning with pref. then that means that the step can be changed upon preference.
Dart belt from the Nerf Vulcan machine gun
Vulcan darts or velcro darts (belt can carry up to 25 darts at a time

the following are all based upon preference since one can make the gun anyway they'd like.
6 pieces of 9cm (3.5in) of 1" PVC pipe (pref)
1 piece of 21.5cm (8.5in) of 1" PVC pipe (pref)
2 bent pipe connectors
2 T-shape pipe connectors
2 end caps

Step 2: Putting Together the Gun

For this step one can make any design they want, but keep in mind that certain ways may not build up enough pressure to shoot darts at a desired speed. Make sure not to make the mouthpiece in a direct line with the chamber (holds the dart) otherwise this will happen.
If you don't want to run into any problems just follow my design and add a paint job or something to it after.
Step 1: Put a 9cm pipe into the top of a T-shape pipe connector.
Step 2: Put to 9cm pipes into the sides of the same T-shape pipe connector.
Step 3: Attach a bent pipe connector to the end of both the top 9cm pipe pointing right, and one on the right 9cm pipe pointing down.
Step 4: Attach a 9cm pipe with a end cap on the bottom to the bend pipe connector that is pointing down.
Step 5: Make a front out of a T-shape pipe connector pointing down, with the 21cm pipe out of the left side and a 9cm pipe with an end cap pointing out the bottom.

The blue tape was just an aesthetic that I decided to add on.

Step 3: Now Load 'er Up

Basically load as many darts as you want into the belt. You don't necessarily have to push the darts all the way in, actually I found that they shoot further if the end is sticking out a little bit.
Just place the back part of the holder snuggly into the pipe that is part of the back part of the gun.
Then place the front end of the gun over the front part of the holder.

Step 4: Blow Your Brains Out

I know, that's what she said. But seriously in order to fire you must place your mouth over the mouth piece which is the open pipe that is part of the L-shape coming out the top of the back part of the gun.
Blow harder and the dart goes further.
Once fired take off the front end and the dart holder, then place the next loaded dart holder into the chamber and repeat until all the darts are shot.
Then you have finished your new dart gun.

You can also fire darts without the belt by placing them in the barrel (front pipe) of the gun before blowing, however it isn't as strong.

This project also doubles as a marshmallow gun (duh) if you attach the front part of the gun to the back, and place a marshmallow in the mouth piece before blowing.

Please do not shoot your annoying sibling or parents with this. And absolutely do not shoot people's faces!

    the only problem i see is that you have to move the front and back of the barrel in order to shoot one bullet, but otherwise cool :)

    and i have to ask ;does it work well if you do not use the front of the barrel (e.i. just stick the belt on the front and blow) ?

    I used a half inch or one inch pipe, it fits best for those stream line darts.

    No :P but thats what it measured on the tape measure :) if you want to be sure just take a dart with you when you go to home depot or whatever. whichever one it fits snuggly into is the rights one :P

    It's pretty fast once you get good at it. I'm able to shoot it faster than the nerf rifle most of the time.
