I've always wanted to make a homemade airsoft gun that was cheap, but i could never find an instructable that i really liked, so I made one! hope you like it!
Here is a list of the things you will need.
-double sided tape
-small piece of mesh (this is usually in the gun already so that no big chunks of stuff can clog the gun)
-2 part epoxy (optional)
-toilet paper roll (optional)
Step 1: The water gun
The first step is to get a water gun and unscrew all the screws. Then take out the insides.
Step 2: Adding a trigger
The next step is to glue the trigger to where you want it. Since most water guns are different, you have to find the spot that works the best for you. once you want that place, glue it and ( and if you want put on duct tape!)
Step 3: Sealing up the air leaks
Since this gun will have to hold a lot of compressed air, you need to close up the places where air can escape. i used a really strong two part epoxy (JB Weld) and put a lot on it, but you don't have to. then i covered it up with duct tape. ( you don't have to use as much as i did, but i didn't want to take any chances)
Step 4: The barrel
You will need the pen for this step. gut the pen so you only have the tube left.take the double sided tape and wrap it around the end of the pen so it will stay in the whole better.
Step 5: Blocking the bb's from falling in the the air chamber
This step is a little tricky. you have to take the piece of mesh (I show you how to get it in the pictures) and put down the barrel of the gun so you can plug up the whole so the bb's dont fall into the compressed air chamber.
Step 6: Making a handle (optional)
This is an optional step. all you have to do is take some PVC and tape it on to the gun.
