A sprued, three-part upgrade kit for Combiner Wars IronBison/KillBison from LioKaiser. The kit consists of a brace which attaches to the 5mm port at the top of the Combiner Wars tank mold and which supports the two side cannons. The side cannons also have 5mm grips so they can be carried in robot mode.
