News to me.
A quote from a American Airsoft Retailer.
''ATTENTION: Airsoft guns are required by law to have the tip (1/4 inch) of the barrel permanently colored in blaze orange.This is not a real fire-arm, nor can it be modified to fire real ammunition in any way!! The gun will be shipped with an orange barrel plug as to comply with Federal Law!! I understand that removal of the orange tip, any warning stickers or protective markings is a violation of Federal law and will void any and all product warranties''
Could this law change from state to state though ??
