[4EVERM-14]

A quick look at the highpower rule does not indicate a specific color. I have one of the first issued at the nationals which is red. Later versions are yellow. I don't think it matters as long as the device extends into the empty chamber and shows the bolt as open. Bright colors should be a better choice. kle's weedwacker line is generally accepted. Just put a wire nut on the end so it doesn't fall into the barrel.
