Scrap Yard has two sheaths that are molle compatible. The nylon 6" and the Nylon 10". OF course that will limit your knife choices to a scrapper 6 or a dogfather. If you don't mind the cost of a custom sheath (worth every penny for either one) Rainwalker or Leatherface can make a rig for whatever your needs are. You'd just need to send them a PM.
