How to Make a Gas Airsoft Gun
A homemade gun is often called an “airsoft” gun in deference to the replicas created by the Japanese, who aren’t allowed to have gunpowder-based weapons. You can make a homemade airsoft-type gun that will use compressed air as a gas for firing the projectile. You will need hardware supplies and to rent or buy an air compressor. The gas-powered airsoft-type gun you will make will be more powerful than any spring- or electric-powered DIY (do-it-yourself) weapon that you could make.

Tips & Warnings
Wear protective earphones to protect your ears from the sound your airsoft-type gun will make upon firing.
Do not aim your airsoft-type gun at a person or anyone’s pet.
Do not shoot anything other than foam or styrofoam balls out of your airsoft-type gun for safety reasons
Do not over-tighten the valve assembly to the pipe because the plastic valve can break.
