It's a replacement gun for Optimus Prime. It's made of metal, which insured most KO toys won't be able to hold it up. ;-)
Might be but I won't let my KO toys to hold this gun How many people will buy this gun and let KO toys to hold it up anyway ? I dun really think so
^ Some of us don't particularly like the smokestack gun or hideous windvane/banana gun that come stock with the Classics mold. I have the bonus 5mm handle ion rifle that came with PP01 Faith Leader (2nd run) and it looks nice with Henkei Convoy, but I'd like something a bit more in scale (the iGear gun is a bit long and sized more for an Ultra figure like PP01 than a smallish Voyager).
