The Buckaroos are similar to the Vitruvian HACKS “Blanks” figures only they have some minimal paint applications (unlike the Blanks) so they can be utilized more or less out of the box for putting together interesting combinations of parts without adding paint to the base figure.
Ultimately slightly less versatility than the Blanks, but a more straight forward template for those not interested in painting their figures.
The figures can be easily disassembled by unscrewing the back screw, separating the torso and removing the torso and arms.
When you’re dealing with most any disassembly especially the legs from the hip sockets USE HOT WATER OR A HAIR DRYER to keep the plastic soft, or you risk breakage.
This is not a defect of the figure. Those joints must be tight to maintain articulation, and sometimes those joints freeze or the material requires softening to loosen up.
Along with the Buckaroos, there’s a five-pack “Headhunters” set which gives you some assorted heads for either these figures, or for customizing the normal figures.
At the end of the day, the options become almost limitless (especially once you slide in all those great Gear and Accessory Packs).
