How to Make a Homemade Airsoft Gun

Airsoft guns are hugely popular because they both look like a real gun and can shoot pellets with more force than other toy guns. You can make your own version of an airsoft gun; it may not look as impressive as one bought from a store, but it will fire a pellet with more than enough force to justify its having been made. You will need a few hardware items along with a pump-action water pistol purchased from a drugstore or toy store.

Step 1

Empty the water from the pump-action water pistol into the kitchen sink. Let the pump-action water pistol dry.

Step 2

Put a towel on a table. Put the pump-action water pistol on its side down on the towel.

Step 3

Position one end of the straw over the small barrel opening of the pump-action water pistol.

Step 4

Plug the hot glue gun into a wall socket for power. Heat up the hot glue gun. Run a bead of hot glue around the straw to adhere it to the barrel of the pump-action water pistol. Let the glue dry.

Step 5

Wrap electrical tape around the gap between the straw and the barrel. Stop wrapping the electrical tape around the gap after you have circled the straw and barrel 6 to 7 times.

Step 6

Use the scissors to cut the electrical tape off of its spool. Smooth down the end of the electrical tape onto the barrel.

Step 7

Pump the piston of the pump-action water pistol 100 times to build up a lot of pressure for firing off the projectile that will be placed into the homemade airsoft gun.

Step 8

Insert a BB pellet into the end of the straw and slide it down the barrel until it stops at the other end.

Step 9

Take your homemade airsoft gun outside. Hold the gun securely with both hands, sight down the gun barrel at a tree in your backyard and press the trigger.


  • Do not ever, under any condition, aim an airsoft gun at a person. Being hit by a BB pellet can not only hurt, but also put out an eye if the face is struck.


  • Don’t wait too long to use the hot glue gun after it is plugged in--if it gets too hot, the tip could melt the straw when the glue is being applied.
