Our verdict

Bulkarm β Standard Type is a 165 mm, 1/24 scale mech from Kotobukiya's Hexa Gear line. The cockpit opens to seat a Governor figure, which is sold separately, and the hover units on the ankles detach and rebuild into a small hovercraft. It comes with a machine gun with a removable magazine, a heat knife, Bull Armor for the legs and two alternate heads from the Bulkarm α. Kotobukiya US listed it at $61.99 in stock and rates it 15 and up.

We found no owner reviews of the kit itself; the two reviews on Gundam Planet's page describe shipping, not the build. Gundam Planet listed it at $60.95 and USA Gundam Store at $61.99. Kotobukiya notes the photos show a painted sample.

It suits a builder who wants a piloted mech to customize with other 3mm-joint parts. Skip it if you expect a pilot in the box.
