The new EoTech Holographic Sight 557.AR223 has been developed to optimize the functionality of the HWS. The buttons have been moved from the back to the left side for instant access, allowing a magnifier, night vision, or a back up iron sight to fit closely to the HWS body. This new button position allows the user to operate the HWS function switches easier than ever before, especially when used with a 3X or 4X magnifier. The 557.AR223 is configured with a new ballistic matching reticle image for the M4 carbine. The new reticle provides 4 aiming dots for target distances of 0-300m, 400m, 500m, and 600m. |
The HOLOgraphic Advantage 
The holographic patterns have been designed to be instantly visible in any light,
instinctive to center regardless of shooting angle, and to remain in view while
sweeping the engagement zone. Reticles are designed as large, see-through patterns
to achieve lightning quick reticle to target acquisition without covering or
obscuring the point of aim.
Heads Up, Full View
The HWS employs a true Heads-Up Display that eliminates blind spots, constricted
vision, or the tunnel vision associated with tubed sights. All user controls
are flush to the HWS's streamline housing with no protruding knobs, battery
compartments or mounting rings blocking vision at the target area. True, 2 eyes
open shooting is realized. Instant threat identification is achieved by maximizing
the operator's peripheral vision and ultimately gaining greater control of the
engagement zone.
The Magic of Holography
In holography, all the information required to reconstruct the reticle image
is recorded everywhere in the Heads-Up display window. If the window is obstructed
by mud, snow, rain, etc., the HWS remains fully operational , with point of
aim/impact being maintained. Even in such extreme cases where the laminated
window is shattered, the HWS is fully functional! As long as the operator can
see through any portion of the window, the entire reticle pattern is visible
on target...the operator can still engage with confidence.
