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.
Model Updated 12/8/16 to correct tolerances on gun-ports.
The Bisonzooka Weaponoid kit shown in the full robot-mode image is available here.
