How to Make an Airsoft Gun Out of a Cap Gun

Insert the tip of a utility knife into the hole in the muzzle at the end of the barrel of an empty cap gun. Twist the utility knife to enlarge the hole.

Continue twisting the utility knife until the muzzle at the end of the barrel has been completely opened up, even with the edges of the barrel.

Press down on the black cylinder release lever that is to the rear just beneath the round cylinder on the left side of the cap gun. Hold down on the lever to release the round cylinder from the frame of the cap gun.

Swing the round cylinder out from its hinge at the center of the frame of the cap gun to expose the holes that BB pellets will be inserted into so that they can be fired out of the barrel.

Insert the utility knife into the holes on the inside of the cylinder. Twist the tip of the utility knife to enlarge each hole until it is big enough for a BB pellet to be inserted into.

Insert a BB pellet into each of the holes on the inside of the cylinder. Push the BB pellet into the hole with the tweezers.

Insert a cap-gun cap into each of the holes on the inside of the cylinder. Push the cap-gun cap into the hole with the tweezers.

Close the cylinder so that it clicks back into the frame of the cap gun.

Aim the airsoft gun at a target in your back yard, such as the side of the house or a patio chair. Press the trigger to fire off an airsoft BB at the target.
