Now I was doing some research because of a conversation between some of my teammates on the federal requirements for orange tips. Now I have even heard some people assert that the orange tip is not even a federal requirement and this is what I found from secondhand sources. 6mm (0.24 in) orange tips are required when imported to the united states, but are not required when in the field. Personally I was always under the impression that the painting or removal of the orange tip was illegal, but we all did it anyways. I am just looking for more clarification on this subject, always helps to know about the laws that apply.
