i heard an idea somewhere, it was to take apart your marker(especially if you have a mag) and put the valve in one place, body in another, grip frame in another, barrel in another and so on(or in one place dissassembled). when it is dissembled no paintball hating people will be able to tell it is a paintball gun and technically it isnt(its just parts remember) and it will not operate inless put together. Its probably a bad idea but its better thatn nothing.
