Question about 'Doubledealer'

I just managed to find a Earthrise Leader Doubledealer at my local Wal-Mart today. I noticed something odd about mine compared to other figures used in reviews and what not. My Doubledealer's rocket/missile is completely un-painted. It's just solid grey. Is this a variant? running change or what? I haven't seen anyone else with a unpainted rocket/missile for him. It's basically like the G1 version. I also don't notice any other differences.
