Gun for DIA Commander?

Does anybody know of a decently large, black, semi-G1-style gun that would fit in DIA (City Commander mold) Commander's hand? Ultra Magnus has his gun (the City Commander large white G1-style gun), but DIA Commander unfortunately has no such gun add-on that I'm aware of.
Basically I want something that looks somewhat similar to G1 Prime's gun, but on a larger scale that would fit DIA Commander's hand. The BFG is way to big/blocky for me.
Thanks
