EOTech 552.A65/1 Military HOLOgraphic Weapon Sight Review


The EoTech Holographic Sight 552 is fully compatible with all generation levels of night vision intensifier tubes. This EOTech holosight features a special night vision (NV) setting that allows the operator to immediately drop the brightness intensity of the holographic reticle to eliminate any “halo” effect while viewing through an image intensifier tube. The EOTech M552 Holosight can be positioned in tandem behind night vision intensifiers without any “bloom” of the target area. Unlike active IR laser pointer systems, the EOTech HWS is a passive system and emits no muzzle-side signature. While in the NV mode, the EOTech 550-Series HWS is not detectable by enemy night vision surveillance systems, providing operators with a stealthy means for effective nighttime weapon aiming. Thanks to EOTech, tactical operators can combine the proven technological advantage of night vision with a superior CQB sight to achieve greatly enhanced weapon aiming – in complete darkness.

The EOTech M-552 features a unique switch that allows the operator to instantly drop the holographic reticle’s brightness to the NV mode of operation. The operator has the ability to toggle back and forth between the NV mode and the normal day/night operation within fractions of a second. The HoloSight M552 has 10 distinct night vision settings to provide maximum flexibility to the operator. Typically 3 to 4 brightness settings are not enough to support a host of constantly changing conditions including manufacturing variances in the sensitivities of the image intensifier tubes, varying ambient environments, and varying light gathering sensitivities of the human eye across users. The M550 still maintains the 20 normal brightness settings for normal day/night operations.

The typical configuration is with both the monocular night vision system and the EOTech HOLO-graphic Weapon Sight mounted in tandem on the weapon’s receiver. Operators can also witness the holographic reticle with head/helmet mounted monocular night vision image intensifier systems, even on a partial cheek weld on the weapon’s stock. This allows the operator added flexibility and greater versatility when deploying with night vision systems in the ever changing battlefield environments.

About EOTech

EOTech, a division of L-3, delivers cutting edge technology and products in the fields of holographic sighting systems, tactical lasers, illuminators and thermal imaging equipment.  EOTech is dedicated to providing high-quality battle-tested products to law enforcement and commercial markets around the world.

The History of EOTech

In 1972, the Michigan State Legislature established an independent, non-profit research institute, Willow Runs Laboratories. It was later renamed Environmental Research Institute of Michigan (ERIM).

Two decades later, in 1993, ERIM formed Michigan Development Corporation (MDC) to commercialize ERIM technology and create spin-off companies.

In 1995, MDC created EOTech as a wholly-owned subsidiary of ERIM.
