The FUSION Micro Hub is the main component in the system and is required for use of all other pieces.  It solidly mounts to standard M1913 Picatinny Rail via two recoil lug bolts.  The Micro Hub features dual FUSION/Scout interfaces: one top and one overhang.  The top interface will accept the FUSION Fixed or Folding Front Sight components.

It will also provide a direct mount for the most Steiner Optics Lasers.  It requires the removal of the factory QD mount and acts as a direct replacement.  This upgrade gives users the confidence of a hard-mounted aiming system.  When installed on a Steiner laser, the FUSION Micro Hub places it at the same height as the factory mount.

The Micro Hub is reversible, allowing users to place the overhang on either the right or left side of the weapon rail.  The overhang interface accepts direct-mount Surefire Scout footprints (also found on Modlite, Cloud, Streamlight weapon lights) for a 2 or 11 o’clock above bore placement.  It also accepts FUSION Light Wings for cantilever forward or back accessory mounting.
