The battery life will vary by model and battery type (assuming nominal brightness setting at room temp). Models with 2 batteries run for over 1,000 hours. Models with 1 CR battery have a run time of about 600 hours.
Ensure that the batteries are properly inserted according to the diagram on the bottom of the battery cap. Replace the batteries with new, unused, fully charged batteries.
Inspect the battery contact points in the battery cap and on the sight. These contact points are spring-loaded and are surrounded by a rubber gasket that may catch the spring.
Move the contact points around and ensure they are at or above the surface of the rubber gasket. Verify that the contacts are both silver in color and are free of any oxidation.
This is the low-battery indicator.
Replace the batteries, following these instructions:
Use the correct batteries. For an N cell sight, make sure to install only 1.5-volt N cell E90 batteries. Often A23 12-volt batteries are substituted in error, and will damage the electronics.
Use quality, name-brand batteries. These have proven to be the most effective in withstanding a consistent amount of recoil. Many brands of batteries deteriorate more quickly than quality name brands, and can result in failures. Under heavy recoil, inexpensive batteries can bulge and the positive terminal can indent.
Inspect the contacts on the sight body. For models OTHER than XPS and EXPS, the contacts must both be silver in colour. If one contact is dark, or if contacts appear anything other than bright silver, there is oxidation due to battery leakage.
Replace the batteries.
Check with others who have used the sight and compare what you see, to ensure the issue is not with your focal acuity.
Reticle fade as a result of moisture incursion may affect sights manufactured before August 2014. Even for sights manufactured before that date, the effect may not be substantial. The issue is that atmospheric moisture conditions can lead to the HWS’s reticle fading or eventually disappearing. It typically is noticeable first when the reticle appears to dim at the edges of the sight window.
The sight’s age and environmental exposure are factors that accelerate reticle dimming. In many cases, however, this condition can be mitigated by increasing the brightness of the reticle, using the sight’s brightness controls.
What you are seeing may be normal. The reticle circle people usually see online or in print advertisements is a graphic representation of a reticle. The reticle is naturally pixelated and the outer circle should appear to be made up of many small dots. The centre circle should be distinguishable as one dot.
Lower the brightness level of the reticle. The fault is generally caused by the reticle brightness being too high. The reticle is designed to not be so bright as to block the target.
The reticle is optically projected onto the target plane. Focus on it as you would any other object at that distance. Do not focus on the sight housing, as with other reflex sights, but focus on the target. The outer ring is designed to be a reference to centre, similar to a ghost ring.
If you wear corrective lenses for near-sightedness, you will require them to see the reticle in focus. This is because the reticle is projected onto the target plane. If you wear bifocals or have astigmatism, you may see a distorted reticle.
Check with others who have used the sight and compare what you see, to ensure the issue is not with your focal acuity. Do this prior to sending the sight for repair.
Not everyone sees the centre dot as a circle, or sphere. If the dot of your HWS does not appear perfectly round, the distortion may be caused by the way your eye perceives the dot, rather than by some mechanical defect.
Because of differences in the lenses of peoples’ eyes and in environmental conditions, round objects that subtend areas near 3 minutes of angle may appear distorted in a variety of ways.
Some may perceive the centre dot to be like the hub of a bicycle wheel with spokes. If you see this in your sight, look closely at the dot and rotate the sight. If the spokes do not move, then the appearance of the reticle is how your eye perceives the dot. Dimming the sight may eliminate the distortion.
If you notice the issue only in cold temperatures, the sight may be affected by cold weather distortion. Cold weather distortion generally does not affect EOTech-branded HWS manufactured after March 2008. The historical issue with cold weather distortion was that the HWS’s aiming dot experienced distortion of size and shape when the sight was exposed to temperatures below 32° F. This became worse as the temperature approached -40° F. It had virtually no effect in warmer temperatures or at the close-quarter ranges where the HWS is typically used, because at those closer distances the distortion would not have a significant effect on the point of impact. Although generally unnoticeable to the naked eye, the distortion existed at colder temperatures.
Changing the image is not feasible because it would require complete housing replacement. Doing so is more expensive than purchasing a new sight.
Make sure the sight is mounted so the cross bolt engages the front muzzle of the rail slot. Recoil will naturally force the sight forward, but mounting in the forward position eliminates this. Do not over-tighten the mount bolt. The specification is 18 inch-lbs., which is approximately hand-tight, using a coin.
EOTech’s sights experience a point of impact shift away from the point of aim when the sight is exposed to a temperature different from the temperature at which the sight was zeroed. After zeroing the sight at or near ambient temperature (73°F), the zero position will shift during operating temperature changes.
The sight has the potential to shift approximately +/- 5 Minutes of Angle (“MOA”) at -40°F and 122°F. Due to thermal drift, the sight may not return to zero. The sights have the potential of approximately a +/- 2 MOA zero shift upon return to ambient (73°F) after being exposed to any temperature between -40°F and 122°F.
To achieve optimum accuracy, the sight zero should be verified whenever the sight is exposed to marked temperature changes, and the sight should be re-zeroed as necessary.
EOTech’s sights experience a point of impact shift away from the point of aim when the sight is exposed to a temperature different from the temperature at which the sight was zeroed. After zeroing the sight at or near ambient temperature (73°F), the zero position will shift during operating temperature changes. For sights manufactured after October 2016, the typical shift will be between approximately 1.4 and 1.8 minutes of angle (“MOA”). Due to manufacturing variations, however, a particular sight has the potential to shift a maximum of approximately 3.5 MOA at -4°F and 122°F. Sights manufactured prior to October 2016 have the potential to shift approximately +/- 5 MOA at -40°F and 122°F.
Due to thermal drift, sights may not return to zero. The sights have the potential of approximately a +/- 2 MOA zero shift upon return to ambient (73°F) after being exposed to any temperature between -40°F and 122°F.
Shifts result from natural thermal expansion or contraction that is present in various materials as they are heated or cooled, and is greater the more extreme the temperature change. For example, when a sight is zeroed at 73˚ F then acclimated to 50˚ F, less shift occurs. On the other hand, if zeroed at 73˚ F, then acclimated to 0˚ F, more shift occurs. The shift may not be significant to shooters who use their sights at close-quarters ranges. For instance, 3.5 MOA is a shift of .875 inches at 25 yards, and is 3.5 inches at 100 yards. It also is worth noting that thermal effects are evidenced to varying degrees in common optics, as well as in rifle barrels and ammunition as the environmental conditions change. In all events, to achieve optimum accuracy, the sight zero should be verified whenever the sight is exposed to marked temperature changes, and the sight should be re-zeroed as necessary.
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 centre 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. You must do this process utilizing the front and rear iron sights, it will not work without a rear sight.
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.
MOA stands for minutes of angle.
1 MOA is nearly 1 inch at 100 yards.
The centre dot in the standard reticle is 1 MOA across.
The ring in the standard reticle is 68 MOA across.
The windage shaft and the elevation shaft on your HWS move in approx. half-MOA increments. This means every tactile click or single adjustment of the shaft moves your point of aim approx...
1/2 inch at 100 yards
1/4 inch at 50 yards
1/8 inch at 25 yards
All optics experience varying degrees of parallax depending on use and operating conditions. Parallax is an apparent change in the point of aim resulting from a change in the position of the shooter. EOTech’s sights have little parallax when the reticle is in the centre of the viewing window, which is the optimum sighting position and also is the correct place for zeroing the sight.
On the other hand, if the user is looking through the sight at the outer edge of the sight window – an off-axis view – the parallax error might be up to 4±3 MOA (or a total of 14 MOA across the viewing window) at 71˚ F (for a sight properly zeroed). In other words, parallax can increase as the user’s view approaches the edge of the EOTech viewing window. To put this possible amount of off-axis error into perspective, 7 MOA equates to 1.75 inches at 25 yards or 7 inches at 100 yards.
Viewing through the centre of the window achieves the least parallax error. Parallax may increase as temperature changes from 71˚ F. At operating temperature extremes of -40˚ F or 122˚ F, there may be an additional 4 MOA of parallax.
Yes. EOTech HWS are water resistant. The depth to which each model can be submerged varies.
EOTech sights are designed and tested to withstand punishing recoil from a variety of firearms. HWS units have been used on the military's M2 .50BMG machine gun, Smith and Wesson .500 and .460 pistols in Africa, shotguns of all sizes, and can even handle the reverse recoil found in air guns and crossbows.
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.
Advantages of EOTech’s HWS for CQB include:
Speed – The HWS is considered, by most, to be 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.
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 visibility for longer range shooting? Look at partnering the HWS with our G33.STS magnifier. With a magnification of 3x and an adjustable dioptre, the target will be in clear focus allowing the operator to make a more precise shot. The switch-to side mount allows for incredibly fast transition times between close quarter and mid to long range shooting making this combination the best of both worlds.
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.
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 centre dot is dimmer than the laser bore projected dot (the centre 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 centre dot for point of aim.
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.
