Frequently Asked Questions (FAQ)

A. General

Why is my front lens tilted?

All reflex sight have an objective lens at the front of the unit that is spherical in shape. However, unlike a conventional riflescope, the objective lens in a reflex sight is positioned off axis and appears to be tilted when looking at the sight from the front. The lens is tilted out of the direct optical axis in the x and y directions. This angle of the front lens allows the light from the LED to be reflected back into the sight. Also the tilted lens reduces reflections of the sunlight, so the shooter's position isn't given away by these light reflections. The reflected light of the LED becomes the reticle that the user sees when the reflex sight is switched on. High-quality devices on the market are always recognizable by this feature.

Blurred reticle

If the dot/reticle appears blurred or frayed, there are several reasons for this. The most common mistake is to focus on the reticle (dot/circle dot) when looking through the sight. You can check the correct display of the (weg lassen red/green) reticle by looking into the distance while looking through the sight. Then the reticle and the visual image, both, become clear.

The brightness setting of the reticle also influences the display. (weg lassen of the red/green point). The sight is often set too bright for the ambient light conditions. You can see this, for example, by the halo effect in the inner tube. Please try reducing the brightness by a few steps and look into the distance again. Your reticle should now appear sharp.

Another option for checking the reticle is the eye relief to the sight: Take a photo of the reticle by focusing from about 30 centimeters. The reticle image should then be clear.

Sometimes the blurred perception is due to your eyes themselves. You can check this by focusing on the blurred part and then turning the optics clockwise or counterclockwise a few times. If the blurred part rotates, then there is a defect in the sight. If the blurred area does not turn, this could be an indication of astigmatism or other impairments of perception.

Due to the coatings on the lens of the optical sight, a certain glare will occur in reflex/reflective optics. Glare is more noticeable in low light, indoors with ceiling or background lighting. Glare is exaggerated when the optic is held in the hand instead of being mounted on a firearm.

What is parallax?

The parallax describes the angle that arises when an object is viewed from two different locations, and which can be observed as an apparent displacement of the object against the background.

If you place one index finger about 15 cm in front of your nose and the other index finger at arm's length and align them, you will see a visual movement of the fingers as you move your head to the side or up and down. The same ( weg lassen thing) happens with the reticle of a firearm optic.: if you move your head too far, the aiming point shifts.

What does parallax free mean?

If a firearm optic is parallax-free, it means that the aiming error due to manufacturer setting is excluded for a certain distance. This parallax error is corrected for firearm optics by shifting the lens to the desired firing distance. From this distance, the image of the object is exactly in the plane of the reticle and the position of the reticle does not change even when looking into the optic from an angle, but remains (weg lassen firmly) on the target. If you aim at a closer object, your aiming point may change because your eye is not in the center. This can cause problems when shooting at a very close or very far object. Holosun optics is free of parallax from a distance of 25 meters onwards!

B. Product

What distinguishes HOLOSUN® from other sights?

There are various aspects that distinguish HOLOSUN® from other providers and other technologies. Quite simply: the technology and the price. With the reflex sight technology, the sight does not emit an active light beam, which is why the reticle cannot be perceived by the target. There is no enlargement, but there is parallax freedom. And that enables aiming with two eyes open. In addition, HOLOSUN® is characterized by the interchangeable reticle of most of out models: Here you can switch between dot or circle or circle dot reticle. With these features, we offer hunters, competition shooters and MIL/LE units sights at an unbeatable price.

What are the differences between the models?

The models basically all work the same and differ only by individual, device-specific features and technical data. Some models, for example, have a switchable reticle, other models do not. Some have a titanium housing, others are made of aluminum, some have an alternative power supply, such as a solar panel or a supercapacitor, some entry models do not. The lens and tube size also varies depending on the model series. In addition, there are various equipment features, such as flip-caps, ARD / killflash, QD mounts, or risers. The technical data can be easily compared using our online product comparison tool or the current HOLOSUN® catalog.

Micro versus Tube and Open versus Enclosed: Which sight for the task?

It's a matter of taste. Some like smaller more, others prefer big ones. The micros are of course smaller and lighter, while the tubes and open sights offer more viewing area. Additional filters can also be easily used for tubes. The choice of the right sight is therefore a question of optics, the area of operation and personal preferences.

How far can I aim with the sights?

With a HOLOSUN® sight you can aim infinitely far from a technical point of view, the limit is the own visual acuity of your eyes. With a magnifier you can support your eyes noticeably and significantly increase the range.

What is the difference between red dot and laser sights?

The reflex sights do not emit any visible light beam, so the reticle is not perceptible by the target. With a laser sight, an active light beam is emitted, which is why the target can see the laser point.

How do the solar panel and auto mode work?

The solar panel is a light sensor. In auto mode, this controls the brightness of the reticle, adjusts it to the ambient light (the area around the shooter, not the target) and it ultimately supplies the sight with power. Important: If you want to test the functionality of the battery, do not cover the solar cell under any circumstances. Otherwise, the sight "assumes" that you are standing in the dark and automatically reduces the brightness to night mode. The red dot is then no longer recognizable under normal lighting conditions. To test the battery, you should try out the sight in a pitch black room without covering the panel. If you see the reticle, the battery is working properly. And if you want to adjust the brightness of your reticle yourself, simply switch to manual mode.

How long does a battery last?

The battery life depends on the type of sight. When operating a dot reticle, the duration is 50,000 hours and when operating the circle dot reticle 20,000 hours (at brightness level 6).

What is the best way to zero the sight?

Everyone does it a little bit different. The optimal distances are between 25m and 50m. You can see exactly how to adjust the alignment of your reticle in the customer manual that comes with the sight.

Are there spare parts available?

Yes, you can find all spare parts in our Shop.

C. Area of operation

E. Maintenance / Care

How do I maintain and clean my HOLOSUN® red dot sight?

The sight is a precise optical instrument and should be handled with extreme care. Before cleaning the lenses with a microfiber or damp cotton cloth, coarse particles must be blown from the surface. Remove fingerprints or oil with a lens cleaner, a soft cotton cloth or a microfiber cloth; avoid cleaning with dry cloth or handkerchiefs. No special maintenance is required on the surface of the housing. Do not use organic solvents such as alcohol or acetone. Do not try to disassemble the device. The device has a nitrogen filling, which you would inevitably destroy when dismantling. The internal parts have to be specially cleaned, are sealed and have an anti-fog coating. Any attempt to disassemble will void the warranty. If repairs are required, please contact our Service Center.
