All airsoft guns are required to have the tip (1/4 inch) of the barrel permanently colored in orange by Federal Law. Any person who changes, alters, removes, or obliterates any coloration or markings that are required by any applicable state or federal law or regulation, for any imitation firearm (replica firearm), or device in any way that makes the imitation firearm (replica firearm) or device look more like a firearm is guilty of violating the state or federal law.
Why does my gun have an orange tip?
