EOTech 553 - Manual (Page 11)

The reflex sight offers extremely fast target acquisition in Close Quarter Battle (CQB)
using the large ring, and aiming precision in longer range engagements (using the
MOA Dot) without obscuring the target.
Another advantage of the Reflex Sight is the full field of view which allows the operator
better situational awareness. The Reflex Sight employs a true heads up display
(HUD) window that eliminates blind spots and constricted or tunnel vision associated
with scope sights. Controls are inset into the Reflex Sight housing with no protruding
knobs, battery compartments, or rings obscuring the target. Utilizing natural binocular
vision is an advantage of this sighting system, as well as additional threat
identification through increased operator situational awareness and peripheral vision.
The reflex sight can operate in tandem with Generation I – IV+ night vision intensifier
tubes. Operators can see the holographic reticle image with helmet mounted or
weapon mounted night vision devices. The reflex sight is a passive system and emits
no signature from frontal or from a peripheral aspect. While in the NV mode, the sight
is undetectable by opposing force night vision equipment. The HWS can be
positioned behind night vision systems without any “bloom” on the target area.
The primary use of the reflex sight is for the M4A1 carbine and CQBR in Close
Quarters Battle. The reflex sight is not however, limited to carbines. The reflex sight
is currently employed on medium caliber machine guns, grenade launchers and less
than lethal projectile launchers. The sight provides a 1X (no magnification) sight
picture and is not designed as a long range sight system, however, it can be used as
effectively as iron sights on targets to 300 meters.
