EOTech 552 HOLOgraphic Weapon Sight is by far the most popular HWS model. This NV compatible, AA battery holographic sight is the sight of choice by military units like Stryker Brigade, 10th Mountain, and 3rd Infantry. Standardized by the DEA, ATF, and FBI SWAT, the EOTech M552 Holo Sight is battle proven to withstand the abuse that any harsh environment, high powered weapon platform, or military mission can dish out.

This EoTech Holographic Sight is fully compatible with all generation levels of night vision intensifier tubes. ThisEOTech 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 EO-Tech 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 EO-Tech 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 HOLOgraphic 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 cheekweld 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.
