The KFA-2 ×2, mounted on an M6D

The KFA-2 ×2[1] is a UNSC scope used on the M6B, M6D, M6F, M6G (Army Variant) and M6H[2] pistol sidearms but not on any of the other weapons in the M6 Series.


The KFA-2 ×2 is a 2× magnification, smart-linked scope that relays visual data directly into the user's HUD. This stands in contrast to normal optical scopes such as the one featured on the BR55 Service Rifle, whereby the user have the ability to look into the scope, but the latter can also relay the visual data directly to the users HUD.

Infantry and other military personal that do not wear a helmet with a visor or an eyepiece, has this HUD interface overlaid their normal sight via their Standard or Command Neural Interface. This scope was only featured in Halo: Combat Evolved, Halo: Reach and Halo 4 and was absent in Halo 2 and Halo 3. The reason is because Bungie decided that the pistol behaved more like a rifle with the scope.


  • Because of this sight, Robert McLees commented that Halo: Combat Evolved players used the M6D more of a semi-auto rifle than a handgun. This led to the M6C replacing the M6D in Halo 2.[citation needed]
  • The M6C/SOCOM featured in Halo 3: ODST uses a similar smart-linked scope, the VnSLS/V 6E, which has a 4× zoom, rather than 2× as with the KFA-2.
  • The scope may originally have been intended to be a laser aiming module. When using third-party tools to import the pistol's first-person model tag into a 3D editor, a marker named "#laser" appears in front of the scope.
