EOTech 552

Product gallery:

Model 552 is in use by military forces and government agencies like the DEA, ATF and FBI.  It's night vision-compatible.

Are you a sportsman interested in hunting with night vision?  Give the 552 another look.  The 552 is EOTech's most affordable night vision-compatible sight and it partners with most night vision-devices.  The 552 is designed to increase your speed to target even after the sun goes down.
**Please Note: The XR308 reticle was designed specifically for the military M240 machine gun.  It should be used with .308 cal with 150 gr M59 FMJ at roughly 2,800 fps with a 24.8” barrel.

The HWS uses state-of-the-art digital electronics design. Twenty brightness levels ensure proper brightness control in either low light or very bright sunlight. An on-board microprocessor provides automatic battery check indicator, up/down brightness scrolling and programmable auto shutdown features. All electronics are fully encapsulated in shock absorbing resin compound.

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.

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.

The HWS is designed to withstand Mil-Spec drop tests and still remain fully operational and hold zero. The HWS has been extensively tested in a punishing recoil simulator generating 3,500 G's of acceleration in less than 0.5 milliseconds (the recoil of a .454 Casull revolver) as well as various environmental chambers).

The Heads Up Display is constructed with a 3 layer, shatterproof laminate glass that is 3/16" thick for added durability. Additional protection of the Heads Up Display is provided with a "roll bar" ruggedized hood.

The HWS does not emit any muzzle side position revealing light signature...the projected reticle pattern is visible only to the operator. Even Gen III night vision equipment cannot detect muzzle side signature of the operator's position.

All optical surfaces are flat and treated with anti-reflective coatings eliminating additional muzzle side signature due to reflective glare. No need for costly glare elimination filters that reduce the effective light transmission and further dim the target area.

The Model 550 HOLOgraphic Weapon Sight (HWS) is fully compatible with all generation levels of night vision intensifier tubes.

A special night vision (NV) setting 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 M550 can be positioned in tandem behind night vision intensifiers without any "bloom" of the target area. Now, operators can combine the proven night vision technological advantage with a superior close quarters weapon optic to achieve greatly enhanced weapon aiming - in complete darkness.

Unlike active IR laser pointer systems, the HWS is a passive system and emits no muzzle-side signature. While in the NV mode, the HWS not detectable by enemy night vision surveillance systems, providing operators with a stealth means for effective nighttime weapon aiming.

Field of View: Aimpoint Comp and EOTech HWS

The EOTEch advantage is clear to see. EOTech's HWS's field of view is nearly 4 times as wide as the Aimpoint Comp M2's. The greater field of view means improved situational awareness and faster threat identification. The HWS offers 10 night vision reticle settings compared to the Aimpoint Comp's four settings.
