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. 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 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 / blurred point

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

The brightness setting of the reticle also influences the display of the red/green point. The visor 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 red/green point 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 our 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 optics. If the blurred area does not turn, this could be an indication of astigmatism or other impairments of perception.

What does parallax mean?

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 virtual movement of the fingers as you move your head to the side. The same thing happens with the target point of a firearm optics: if you move your head too far, the target point shifts.

What does parallax free mean?

If a firearm optics is parallax-free, it means that the target error due to manufacturer setting is excluded from 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 optics from an angle, but remains firmly on the target. If you aim at a closer object, your target point may change because your eye is not in the center. This can cause problems when shooting at a nearby object. Holosun technology is free of parallax from a distance of 25 meters!

B. Product

What distinguishes HOLOSUN® from other sights technologies?

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 visor does not emit an active light beam, which is why the red dot/circle point 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 the 500 line: Here you can switch between red dot or circle dot reticle, or combine both. With these features, we offer hunters, marksmen and special forces military-grade sights at an unbeatable price.

What are the differences between the models?

The models basically all work the same and differ only in their special features and technical data. For example, the 500 series has the interchangeable reticle, the 400 series does not. All products with a “C” in their name have a solar panel. The lens size also differs depending on the model: the micros have a 20 mm diameter, the tubes 30 mm. There are also various features, such as dust flaps (flip-backs), kill flash or line of sight elevation (high riser mount). Technical data can be easily compared using our online product comparison and the catalog.

Micro versus Tube and Open: Which sight is better?

It's a matter of taste. Some find smaller better, others big. 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 application and personal preferences.

How far can I aim the sights?

With a HOLOSUN® red dot sight you can aim up to 100m. With the addition of a magnifier, up to 300m.

What is the difference between red dot and laser sights?

The red dot sights, i.e., reflex sights, do not emit any visible light rays, so the target point is not perceptible by the target. With a laser sight, an active light 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 nothing more than a light sensor. In auto mode, this controls the brightness of the reticle, adjust it to the ambient light (the area around the shooter, not the target) and it ultimately supplies the sight with energy. Important: If you want to test the functionality of the battery, do not cover the solar cell under any circumstances. Otherwise, the sight "thinks" that you are standing in the dark and automatically reduces the red dot brightness to night mode. The red dot is then no longer recognizable under normal lighting conditions. To test the battery, you should try the sight in a pitch dark 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 red dot reticle, the light duration is 50,000 hours and when operating the circular dot reticle 20,000 hours (at brightness level 6).

What is the best way to shoot the sight?

Everyone does it a little differently. The optimal distances are between 25m and 65m. You can find out exactly how to adjust the alignment of your reticle in the customer manual that comes with the sight.

Are there spare parts?

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

C. Area of application

What type of hunting are HOLOSUN® red dot sights suitable for?

The sights are suitable for all hunts where you shoot from short distances (e.g., push-hunts).

Are the sights suitable for night vision?

Yes, the sights can be combined with night vision devices (with 2 NV levels).

D. Assembly

With which weapons are the HOLOSUN® red dot sights compatible?

HOLOSUN® red dot sights are supplied with Picatinny mounts (compatible with the Aimpoint® Micro Footprint). For certain models (mainly Micros) there are also Sauer303, Tikka T3, Weaver and Blaser assemblies in our offer. The mini sights are compatible with the Trijicon RMR standard.

Which rails are included?

Our HOLOSUN® red dot sights are supplied with Picatinny mounts. For the Micros there are also Sauer303, Weaver and Blaser assemblies in our range.

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 other oils 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.
