there are quite a few options. if your doing it yourself youll need to prep the stock depending on what your gonna use. krylon makes spray paint that sticks to plastic. just follow the instructions. you can also have it camo dipped but its like 75$. what color or pattern are you looking for ? if cva has other colors in stock i would just buy a new one and sell the old one. krylon also makes webbing paint in a spray can that might look nice too add to your gray stock. whatever you do just give it a clear coat in flat or satin when your done to protect the finish better. duracoat paint is an option too. just do a search.
