Airsoft guns mimic the look of a real weapon by duplicating the many parts that make up a weapon. You can disassemble a P99 spring-powered airsoft gun to clean it for continued, effective use by following almost the same procedure as disassembling the real gun. You do not need special tools to disassemble the P99 airsoft gun, as common household tools are all that are needed.
Use a finger to press down on the magazine release latch on one side of the P99 airsoft gun’s handle. Pull the magazine out from the bottom of the handle.
Cock the sliding plate of the P99 airsoft gun. Fire the P99 airsoft gun into the open bowl of a toilet to ensure that there are no projectiles inside.

Remove the screws from the top edge of the barrel, from the back edge by the hammer and from the gun handle with the Phillips screwdriver.
Turn the P99 airsoft gun over on the bath towel. Remove the screws as was just done on the other side using the Phillips screwdriver.
Stand up the P99 airsoft gun on the bath towel. Use the Phillips screwdriver to remove the screw that is at the back just before the hammer.
