Introduction: How to Make an Airsoft Machine Gun Under $20

Picture of How to Make an Airsoft Machine Gun Under $20

In this Intructable, I'm excited to share how I made an airsoft machine gun using canned air! Pictures are coming, I just have to get the camera ready :)

Materials:

-Canned air (also called air dusters or compressed air) with the straw in the packaging. They range in sizes and the larger ones will obviously last longer but are harder to hold.

-A bottle with a screw-on cap, like a coke bottle

-A cheap bic pen with a straight tube

- DUCT TAPE!!!

- drill (or a way to puncture the cap and bottle)

-Airsoft bb's

This gun works due to having an air supply under the bb's, causing them to jiggle around. At the same time, there's only one place for air to escape, and that's where the bb's go too because we are making a little vacuum. I haven't clocked the speed yet, and I don't know the pressure of the air can (I just bought it from the store). However, this is easy to make, fully functional, and more.

Step 1: Step 1: Prepping the Bottle

Drill a hole the diameter of your bic pen in the cap of your bottle- this is where you will put your barrel for the gun!

Step 2: Step 2: Bic Pen Prep

remove BOTH ends of the bic pen, leaving an empty tube. This is roughly the diameter of an airsoft bb, and will be your barrel for the gun.

Step 3: Step 3: Cap + Pen Attachment

Slide the bic pen into the hole you just created in the bottle cap, and use your duct tape to secure it in place. Make sure the pen will protrude INSIDE the bottle, as bb's have to be fed into it. Put this aside- we won't be using this until later in the project.

Step 4: Step 4: the Bottle

Now, you have to puncture the bottle to fit your air can's straw.

Step 5: Step 5: Adding the Straw

Slide the air can's straw in about halfway, and then tape it in place- CREATE AN AIRTIGHT SEAL!!!!!

Step 6: Step 6: Add the Air Can

put the air can back on the straw, and secure the can with duct tape, rubber bands, etc. You don't want to drop the can when shooting :)

Step 7: Step 7: Lock & Load

Take your airsoft bb's and fill the bottle about halfway. Screw the barrel/cap attachment you made on, and you are ready to fire!

Step 8: Step 8: Shooting

When you fire, remember to squeeze and hold the trigger for a stream of bb's or tap it for a burst of them. For your safety, please be careful where you shoot- I do not hold any responsibility for any injuries due to people who abused or misused their machine gun. I will post pictures as soon as I can get batteries for my camera :)

I would like to thank NightHawkinLight for his original post- he created the picture above. That is what motivated me to make my own.
