I broke one this Spring while turkey hunting. I called them with the intention ordering a new one and to find out how to replace, but rather than tell me how to do it, they encouraged me to send it directly to them and they would replace free of charge. The turn around was only about 10 days.
I don't know what their charge, if any,is on a color change preference, but might be worth a call. I don't have their telephone number, but you can go to their website and get it there.
