The Build Booster MK-II is exactly the same 1/144 flying unit that comes with the HGBF RX-178B Build Gundam Mk-II, but in this case you have the opportunity to buy it as a standalone item to combine with other High Grade models: unmissable! The spacecraft main body can be attached to the back of the models, while the two side cannons can be hooked to the forearms of the robots, or they can be separated from their outer armor to be held as classic rifles (Beam Rifles Mk-II). This kit is compatible with many High Grade gunpla models, some of which are:
As always, it's recommended the use of a pair of hobby nippers to properly detach the parts from the runners. All components are already molded in separate colors, but of course they can be painted according to your taste with suitable paints or Gundam Markers. The kit also features a small stickers sheet to add details to the Build Booster Mk-II. The Action Base 2 by Bandai, shown in the images, is sold separately. The various gunpla models shown are also sold separately.
