Holographic Weapon Sights FAQ

How is the HWS mounted?

The HWS is equipped with an integral mounting platform to interface directly with any standard 1 Weaver dovetail or Picatinny Mil spec 1913 mounting rail:

  • Tactical weapons, typically including sub guns, M16/AR15 carbines, and shotguns
  • Weapon platforms with a Weaver dovetail base on the receiver, including M4/M16 flat tops
  • Handguns (although holstering is a problem)

Other mounting options include:

  • Tapping the receiver of the gun
  • Using a non-gunsmithing add-on mounting platform to provide the dovetail base
  • Using cantilever shotgun barrels

Most standard tactical weapons have 1 or 2 mounting solutions, which vary in design. They allow co-witness of the iron sights, access to the iron sights, and cheekweld positions. Make sure to mount the HWS with the battery compartment facing the muzzle and away from the operator.

Is any light that can be seen cast on the target?

No, there is none. Unlike a laser or red dot sights, the holographic image projects no forward light onto the target. So there is no position-revealing light.

The projected reticle is visible only to the operator. The operator remains completely hidden down-range, even from night vision systems.

In addition, there is no muzzle-side reflective glare from coated lenses like on red dot sights, scopes, or binoculars. The HWS does not need any costly add-on filters that would also significantly reduce the effective light transmission and make the target less visible.

What is minutes of angle (MOA)?

MOA stands for minutes of angle.

  • 1 MOA is nearly 1 inch at 100 yards.
  • The center dot in the standard reticle is 1 MOA across.
  • The ring in the standard reticle is 65 MOA across.

The windage shaft and the elevation shaft on your HWS move in half-MOA increments. This means every tactile click or single adjustment of the shaft moves your point of aim...

  • 1/2 inch at 100 yards
  • 1/4 inch at 50 yards
  • 1/8 inch at 25 yards

Can I use the HWS for long-range engagement?

Yes. The HWS can be used with extreme accuracy for engagement to 300 meters.

The HWS provides a much greater field of view than a magnified scope, providing the operator with more visibility in a tactical engagement area.

However, the clear objective advantage is in close-quarters battle (CQB) situations, in which speed is a must. The HWS is an obvious choice for an M16 or M4, weapons used for both CQB and longer-range engagements.

Need to increase your visability for longer range shooting? Look at partnering the HWS with our G33.STS magnifier. With a magnification of 3.25x and an adjustable diopter, the target will be in clear focus allowing the operator to make a more precise shot.  The slap-to side mount allows for incredilby fast transition times between close quarter and mid to long range shooting makeing this combination the best of both worlds.

Is the HWS waterproof?

Yes. EOTech HWS are waterproof. The depth to which each model can be submerged varies.

Who else is using EOTech HWS?

The nations tactical elite choose the HWS to boost operator performance and provide a speed advantage over other optical systems.  EOTech products are battle ready and have proven themselves time and again.   The majority of this countries 3 letter agencies run EOTech Holographic Weapon Sights by choice and the EXPS3 has been standardized by the United States Special Operations Command (USSOCOM) as the leading optic for close quarter battle situations.

How does the HWS compare to red dot sights?

Please see the holographic sight vs. red dot sight page of this website for a comparison.

For what tactical applications can the HWS be used?

Typical tactical applications are with shoulder-mounted small arms weapon systems, such as these:

  • MP5-style sub guns
  • M4/M16 and derivatives
  • Tactical shotguns

The HWS is also used extensively on less-lethal launching platforms:

  • 37 mm and 40 mm
  • Shotgun applications involving bean bag rounds
  • Rubber bullets
  • Deployment of gas munitions

Other applications include:

  • Medium-caliber (.50) machine gun weaponry
  • Shoulder-mounted rocket launchers
  • Grenade-launching platforms

In all cases, HWS greatly enhances speed, accuracy, ease of use, and vision maintenance.

What are the advantages of HWS for Close Quarters Battle (CQB)?

Advantages of EOTech’s HWS for CQB include:

  • Speed – The HWS is the fastest sight on the market today.
  • Vision – Maintenance of the operator’s peripheral vision, with the tubeless HUD architecture and 2-eyes-open shooting.
  • Ease of use – This leads to incredible accuracy, which provides the operator with controlled confidence in his shooting ability.

How to Mechanically Zero an EOTech with M4 Iron Sights

All Eotech sights are designed to co-Witness with iron sights on the standard AR15 platform. Sights with side buttons and/or factory equipped quick detach levers will co-witness in the lower 1/3 of the window. All other models will co-witness in the center of the window. This is based on the model chosen at time of purchase.  

  • Make sure your firearm is unloaded and verified safe.
  • Flip up the iron sights and set the rear sight on the small aperture. If your firearm has a fixed front sight, only adjust the small aperture.
  • With your EOTech turned on, look through the rear peep sight with the front post in view.
  • After obtaining a sight picture, adjust the EOTech so the 1 MOA dot sits directly on top of the front post.
  • Once this is achieved, final zero should be verified using live fire.

Note: When adjusting to iron sights, you are moving the image to the fixed point of aim so your adjustment dials on the sight are in reverse or mirrored.

 

How to Laser Bore Sight Your EOTech

  • Make sure your firearm is unloaded and verified safe.
  • Insert laser sighting device into barrel and project a dot onto a wall at 21 feet (7 yards).
  • Turn the EOTech on and adjust the brightness settings so the center dot is dimmer than the laser bore projected dot (the center dot on the EOTech will not be used in this process).
  • Adjust the EOTech to the projected laser on the wall and align the bottom of the outer circle at the 6 o-clock hash mark position while looking through the EOTech. Complete the zero with live fire at 50 yards using the center dot for point of aim.
