Always be safe and never carry your Airsoft gun openly in a public place.

It is illegal to do so in many countries and can lead to your arrest or serious risk of being injured or killed by other people who may carry real guns! 
Although Airsoft Guns are non-lethal, NEVER brandish your Airsoft gun in a public place. NEVER brandish your Airsoft gun in a private place, unless all persons present.. know that it is not a real gun!
The best practice is to always treat Airsoft guns as if they are real, and handle them in a safe manner. 
An accidental discharge from an Airsoft gun can cause serious injuries to the eyes and minor stings or minor injuries to other parts of the human body. Suitable eye protection and clothing are always recommended!
NEVER aim or shoot an Airsoft gun/rifle at anybody who is not in gameplay or is not wearing suitable eye protection and clothing.
Be safe, play safe!
