Was there ever a black gun released for MP-01/04 Prime, or did that only come with MP-02 Ultra Magnus? The grey gun that came with Prime does the trick I suppose, but I'm sure I'm not alone in realizing it should be black. I only recently noticed that a black gun comes with UM, but obviously I don't want to buy that sorry excuse of a repaint just for one accessory. So... any advice where to find a black version for MP Prime? Like say, did someone such as JustIToys ever release one? Thanks.
