"Emitted Light Optic with a floating illuminated reticle."
— In-game description

The ELO returns as an attachment in Call of Duty: Infinite Warfare. It functions similarly to the previous iteration, but the reticle can now be customized. The ELO sports a new ability, as it also displays an ammunition counter for the current magazine. It also has a different reticle, featuring a yellow crosshair instead by default.

The ELO is integral to the Type-2 and the HVR, but can be replaced with any optical attachment equipped. The Type-2's ELO does not feature an ammunition counter, however.
