What are my options for a offset light mount for this light? I know it doesn't fit regular scout mount
Any that fit a Millenium weapon series. As of right now, basically only the Danger Close Scout Mount and Offset Adapter.

If you're running a tube type forearm Impact Weapons Components has this:

There have been rumors of the Haley Strategic mounts being available at some point for the millennium/620 mounting pattern but those aren't out yet.
