Pain Strider - Armiger Helverin conversion kit

The smallest of the chaos titans, about the same size as an Armiger.

This is just the top half, designed to fit on the legs of a Games Workshop Armiger (Helverin or Warglaive) as a 28mm scale model similar to the Slaanesh Hell Strider from Epic 40k.

It could also be made to work with Seb's Armour Bearer legs:

And of course you can pop it on pretty much anything you want, like maybe Dunecrawler legs or anything else really.
