Together with the Bulkarm Lamda Jackal.

This kit is the Bulkarm Lamda Osteon, released as part of Kotobukiya's Hexa Gear series. Essentially, it's a color variant of the Hexa Gear Hexa Gear Bulkarm Lamda Jackalwith the molded color changed to a beige tone, and it adds the separately sold Heavy Weapon Unit 41 Modular Carbine to the lineup.

So the structural features and basic accessories of the main body are identical to the Bulkarm Lamda Jackal — it's essentially just the heavy submachine gun swapped out for the Modular Carbine. The Modular Carbine lets you freely combine the carbine, barrel, scope, handguard, and grenade launchers, so you can put together all kinds of custom weapon loadouts. The Bulkarm Lamda body itself continues to deliver excellent build quality, great articulation, and solid joint strength. It's a kit that's a lot of fun to pose around with the new weapon.

That said, this is a pretty typical color variant + weapon add-on release with no new molding. But since the base kit is genuinely good, if the style appeals to you, this is definitely a solid mecha model worth recommending. :-)
