You don't need the orange on the rifle once you have it
That is only required when being shipped from the manufacturer to the buyer. Once you have it, you no longer need it at any time.
Though it is a good idea to put some orange on it, just to stay safe..... or you can put a note on the inside of the box letting them know that it is an airsoft replica, and unable to fire live ammunition at all.
