551.A65 and 552.A65 Military Units

Model 551.A65 with N Batteries and Model 552.A65 with AA Batteries

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.

The M550's unique switch 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 M550 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.

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.

Extreme Durability

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 has been designed and tested to provide consistent, reliable performance even in the most hostile operational environments. It is waterproof, fogproof, shockproof, and temperature proof.

Night-vision Compatability

The typical configuration is with both the monocular night vision system and the HWS 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.

Tandem operation with Generation I - IV N.V. tubes. Toggle Switch with 10 settings (immediate drop to Night-vision mode).

Field of View

.Aimpoint Comp and EOTech HWS - The EOTEch advantage is clear to see. EOTech's HWS field of view is nearly 4 times as wide as the Aimpoint Comp M2. 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.

Testimonials

"Let me tell you, that sight is awesome... there have been a few bad guys on the opposite end of that site, and because of your superior craftsmanship, I am writing you this letter a grateful man."
5th Group Special Forces

"I have literally banged, dropped, slammed and scratched the sight to the point that the finish is coming off and there are gouges in the casing. The sight has been on my weapon since February 2003 and it has maintained zero ever since. It has weathered multiple sand, dust and mud storms... and it still operates flawlessly."
Special Operations in Iraq

"The sight is by far the best I have ever used. That is including my time spent in Marine Recon and Special Operations Units."
Lt. Ron Gana
Arkansas Dept. of Correction

"I zeroed with, and then utilized the sight today....Wow! I really like it. This sight allows for a true "two eyes open" sight picture."
Officer Allan Garcia
Middletown PD, RI Special Ops Unit

"The sight was very fast in CQB situations. I have never used another sight that was faster or easier to use."
Kevin Marshall
Deputy Sheriff
San Juan County, NM

"We call the HWS...the "heat"
Special Forces Operator
Ft. Lewis, WA

"As for the sights, well... the best way to put it is... they are like cheating. Really, those things are the best tool that I have. It is so fast and easy to acquire that it's idiot proof. You don't loose the reticle in the bright light (the Aimpoints are terrible for that) and the dot is super easy to acquire."
Spec Ops Operator
