Looks nice, the one problem is the length, shorten it by 30% and maybe make it 10% - 20% wider, as right now it looks longer than the Juggernaut.
Such extreme length would severely hinder it in terms of foreward/aft firepower.
Edit: Also, you may want to clone the Liberty Dread engine section, or make something similar, as without it it would just look strange as far as Libertonian caps go.
