Boom, the orange tip is not going to be the issue. The issue boils down to having a case. Many players are known to replace the "flash"hider with a replica one for the same reason we play this game. Added realism, and yes the orange tip is removed.
However, it is a federal law that when buying, selling or shipping an airsoft replica the orange tip must be present and on the airsoft replica (INTERSTATE COMMERCE ONLY). A small orange tip is not what an officer is looking at when he see a kid or adult with an airsoft replica...they see a weapon. Which is why as a responsible member of the airsoft community you will have purchased a case in order to transport and bring your airsoft replica to the field. As required by all members of SFAA. The factory box that it comes in will be acceptable, but anything shy of these two items and the replica will need to be left in the car.
We want to make the field available to all players. New and old. Experienced and inexperienced. This field is not only going to be a place to play, but it will teach you honor, and responsibility. It wont matter if you have a walmart airsoft replica or a $400 airsoft replica. You are an enthusiast like the rest of the community, so you are welcomed just like everyone else.
Hope that helps.
