IK chain help?

Rane

I'm planning an add-on weapon for various figures that is a belt fed heavy machine gun with a backpack and an ammunition cable.  A year or so back, I think the generation three figures, or the Generation 4 it could have been, had a de-tachable IK chain thingy that could be attached to objects and act as an anchor for the limbs.  Is there a way to duplicate this?  I'm planning on putting the weapon in the hand, equipping the ammo-cable to it and the backpack.

In what? I don't think DS has ever had parentable IK targets, except for some of casual's scripts.
