What you should know before buying a riflescope!

Rifle scopes are so-called aiming aids, like rear sights and red dot sights. The special thing about riflescopes is the optical magnification of the targeted object, as well as the high precision that can be achieved when using a riflescope. ZFs basically consist of several optical lenses that are mounted in a tube, a reticle and an adjustment facility.

The performance of a riflescope depends on several factors and on their interaction: The optics are of course of decisive importance, although it does not make sense to measure the optical performance solely on the basis of a single parameter such as transmission. Many other values ​​such as contrast, resolution and the quality of the remuneration must also be correct.

However, the mechanical quality is just as important: A riflescope is (not only) exposed to extreme loads when shooting. The riflescope has to put that away and it should also be insensitive to the weather. It is important to combine the required robustness with maximum precision, such as the reticle adjustment. This can only be achieved if minimum tolerances are adhered to in the production of optics and mechanics and the highest quality materials are used.

The rifle scope is definitely one of the most important pieces of equipment. Precision, shot resistance and optical performance (light intensity) make a decisive contribution to the shooting performance.

Which rifle scope is the right one depends on a number of factors: < / p>

Purpose which weapon is used personal preferences the reticle (and possibly also the appearance of the optics) financial possibilities

There is a whole range of universally applicable rifle scopes on the market. For example, a riflescope with 2-12x magnification and an objective diameter of 50 millimeters (2-12x50) is suitable for almost every application. Regardless of whether you are sporty or hunting, you are relatively well advised with these values. Glasses with three to fifteen times or three to eighteen times magnification (3-15x50 / 3-18x50) are also very common and belong to this category.

In addition to these, there are special riflescopes that, for example, have a very large lens and as a result, have a high light intensity for use in poor light conditions or have an extra large field of view for fast target acquisition. These glasses are of course superior to the all-rounders in their respective specialty. So you have to ask yourself whether it should be a rifle scope for a wide range of applications or a glass for a special purpose.

Another important point is the reticle of a rifle scope. There is a very large selection here, with considerable differences. There are reticles that are designed for quick target acquisition at short distances, others are better suited for precise shots at long distances. The hunter is more likely to use an illuminated reticle that is suitable for daylight, which also provides a good light intensity at dusk, while the sports shooter is usually well served with a fine, non-illuminated reticle.

It plays a very decisive role of course also the price when buying a riflescope. We offer a wide range of prices up to 700 euros with a wide variety of magnifications and reticles, but you don't always have to go for the most expensive telescopic sight to get a good result.

First of all, the rifle scope required depends on the type of hunt, a high seat hunt requires different optics than a driven hunt.

A driven hunt lens usually has a low (or no) magnification, a slim one Design to enable interference-free viewing of the target with both eyes and a very large field of view. In addition, it is usually very easy to have little impairment of the handling of the weapon and to maintain the ability to shoot quickly and run through.

For the hide hunt during the day the under "Which is the right / best rifle scope are suitable to me?" The already mentioned glasses in magnifications from two to about eighteen times with a 50 lens are excellent. Depending on the size of the area, the enlargement can be up to 25 or even 30 times. At dusk or even at night, a glass with a 56 lens is more advisable to get a little more light intensity.

The reticle of the glass is also a very important point. For high seat hunting, a glass with the reticle on the 1st image plane is suitable, which enables us to calculate the distance to the target in order to be able to adjust the stopping point accordingly.

Even if older hunters like to tell something else : An illuminated reticle - and one that also works in daylight - is extremely useful. It facilitates and improves aiming and thus the shooting performance considerably because the clearly visible point stands out much better from the ground than the unlit reticle of bygone days. This is particularly noticeable when sitting on a dark forest edge.

The choice of the rifle scope depends largely on the discipline. This usually indicates the caliber to be used (shot resistance) and very often also the maximum permitted magnification.

Basically, in shooting sports optical parameters such as field of view, edge sharpness and twilight performance of a riflescope are more likely to be neglected because the position of the target is known and is usually shot during the day or with good lighting. In long range disciplines, the highest possible magnification of up to 50x is required, from 12x magnification a parallax compensation is absolutely necessary.

A lens with the reticle on the 1st image plane is only conditional to recommend. The reticle often covers too much of the target here, so that precise aiming is no longer possible.

The following elements are common to all rifle scopes:

- A tubular body, the tube , which accommodates the optical elements.

- A lens through which the light falls.

- A erecting lens system or a erecting prism system for erecting the image.

- A reticle , which can be adjusted upwards and downwards as well as to the side.

- An eyepiece for viewing the image and for focusing on the image plane.

- A Montage for reproducible alignment with respect to the measuring device or the firearm.

In addition, riflescopes have, depending on the intended use

- , a lighting device or an illuminated one Reticle for use in poor lighting conditions

- A focus setting for variable target distances (parallax compensation)

- A vial for horizontal alignment, especially with

- Variable magnification < / p>

- One n Diopter adjustment

The information on the telescopic sight indicates both the magnification and the diameter of the lens. Example: 4x24 would be a telescopic sight with 4x magnification and 24mm objective diameter. If several values ​​are given in front of the lens, the first stands for the smallest and the second for the largest possible magnification. 2-10x50 is a riflescope with a magnification that can be adjusted between 2 and 10 times and an objective diameter of 50 mm. Any letter codes indicate the reticle, the illumination of the reticle or special lenses. Just to name a few, since every manufacturer has its own special designation:

- AO = adjustable objective parallx adjustment on the lens, but sometimes it is wrong the eyepiece adjustment for focusing with poor eyesight is called "AO".

- AOE = adjustable objective with reticle illumination

- WA = Wide Angle (Wide angle, i.e. particularly large field of view)

- PA = Parallax adjustment (the parallax can be adjusted to different target distances)

- IL = Illumination (the reticle is illuminated)

- FFP = First Focal Plane (reticle on the first image plane)

- SFP = Second Focal Plane (reticle on the second image level)

Several criteria apply to many glasses, the most striking is usually indicated here.

The reticle is the aiming device in a telescopic sight, the so-called crosshair. Depending on the intended use of the riflescope (e.g. hunting, shooting sports, tactical), different types of reticles are preferably used.

When it comes to riflescopes, a distinction is made between the European and American designs. Rifle scopes of European design are predominantly rifle scopes with the reticle in the first image plane, the lens image plane. American-style riflescopes are mainly manufactured with a reticle in the second image plane, the eyepiece image plane. This supposedly small difference has a major impact on the intended use, production and quality requirements of the riflescope.

In profane terms, this means that when the reticle is in the first image plane, the reticle wire or the lens on which the reticle is directed was etched, is located in front of the erecting system of the rifle scope. In the case of a reticle in the second image plane, the etched lens is located behind the erecting system. So here only the image is projected enlarged into the second image plane, without the reticle being enlarged.

Basically, there are two differences for the consumer that are obvious in practice between the two types:

- Reticles in the first image plane are slightly enlarged and therefore do not appear as fine as reticles in the second image plane.

- Production defects, such as dust inclusions in the first image level, have more serious effects on the image of the optics. Quality defects can be identified relatively quickly.

However, these errors can be compensated for with modern manufacturing processes. Today it is possible to produce reticles in the first image plane that are just as fine as reticles in the second image plane and dust inclusions in the optics are almost impossible due to modern production conditions.

Rifle scopes with the reticle on the 1st focal plane are more suitable for hunting and can only be used to a limited extent for sporty shooting. The big advantage here is first of all that you can calculate the distance to the target. As a result, the parallax compensation can be adjusted accordingly and / or stopped accordingly before the shot. This is an advantage that does not come into play in sport shooting, since the distance to the target is usually known here. A major disadvantage of sporty shooting is the increasing size of the reticle. With increasing magnification, it can quickly happen that too much of the target area is covered and precise aiming at the "10" is no longer possible.

Rifle scopes with the reticle on the 2nd image plane can basically be used for both hunting and sport shooting. However, if the distances to the target are not already known during the hunt (you often know exactly how far the hide is from the edge of the forest), it is a little more difficult to calculate the distance. A MilDot or reticle is also required, but the distances between the reticle markings change with the change in magnification. Most of the time you have the dimensions given by the manufacturer at full magnification. These halve or double when changing to the smallest or largest magnification. The calculation of shelves, lead measurements or the correction of the breakpoint is significantly more difficult and requires a high level of practice. This can be compensated for by an appropriate lens with parallax compensation and reticle adjustment. Basically, you also need precise knowledge of how the rifle scope works and practice in order to be able to use such fine instruments correctly. Alternatively, we also offer rangefinders , which do not make it necessary to calculate the distance to the target. < / p>

The eyepiece is the side of the optics facing the eye.

The task of the eyepiece is to enlarge the image generated by the objective or erected by the prisms. If it is properly focused (focused), the light rays emerge parallel from the eyepiece and the viewer has the impression of looking relaxed into the distance.

The optical quality (color correction, image distortion, image sharpness) is enhanced by the The quality of the eyepiece is also determined.

The lens is the side of the optics facing the target. Often people talk about the lens when referring to the front lens. The front lens is the foremost lens of the lens. From a formal point of view, a lens is a lens system consisting of several lenses.

The lens is the most important part of an optical system; it collects the light on a larger area than the "unarmed" eye can. As a result, the rifle scope is able to enlarge distant objects with a high resolution. The diameter of the front lens of the objective determines how much light falls into the binoculars and is therefore of great importance for the brightness, the exit pupil and the twilight factor.

Parallax is a target error that occurs when a shooter does not look straight through the scope, but at an angle. The optical axis of the riflescope and the archer’s visual axis then deviate from each other, and the archer sees the reticle shifted to a different position without noticing it. If the shot is triggered, there is a deviation from the point of impact. Most riflescopes, however, are parallax-free up to a distance of 100 meters, which means that there is no shifting of the point of impact, regardless of how you look through the glass. When shooting at significantly longer distances, the glass must be adjusted accordingly to also take this Distance to be parallax free. The parallax compensation with which this adjustment is carried out is therefore a useful device on long range or long-range riflescopes.

If you look through a telescopic sight you can only see a section of the image, which you can see without a telescopic sight. The size of the image section, which is specified in degrees or meters, is called the "field of view". The indication of the size of the field of view is usually given at a distance of 100 or 1000 meters.

It is important to know that the edge sharpness of an optic always decreases due to the construction of the lenses. The lenses in binoculars have to be curved for technical reasons, which logically means that only the center point is really 100% sharp. The human eye, which automatically corrects slight blurring, notices this only at the edge. The visual error and the edge sharpness go hand in hand, depending on the lens (s), a larger field of view is usually only possible at the expense of reduced edge sharpness. A perfect edge sharpness is only possible by reducing the field of view.

The zoom factor is a designation for the magnification factor for a riflescope: With a magnification of 1.5 to 6 times, the riflescope has a zoom factor of 4 or a four-fold zoom factor, because six divided by 1.5 is four. A 2-12x riflescope accordingly has a zoom factor of six.

The exit pupil is the circular opening that you see when you look at the eyepiece of a riflescope from a distance of about 30 centimeters. The size of the exit pupil can be calculated by dividing the objective diameter by the magnification, so an 8x56 riflescope has an exit pupil of 7: 56: 8 = 7. The exit pupil is a purely arithmetical variable and says little about the actual performance of an optical system under poor lighting conditions. The human pupil expands to a maximum of seven millimeters in the dark, ideally the exit pupil of a rifle scope is not significantly smaller for use in twilight.

The interpupillary distance is the distance between the eyepiece lens and the eye, which enables the target image to be seen fully and clearly. The interpupillary distance is particularly important for weapons with strong recoil, since if the interpupillary distance is too short, the rifle scope can leave unsightly lacerations on the eyebrow. Of interest is the interpupillary distance and the corresponding mounting of the scope, but also for rifle scopes with high variable magnification, because the correct one Eye relief at the highest magnification has the greatest impact. The exit pupil also comes into play here; it describes the diameter of a circle in which the eye can perceive the target image. The exit pupil typically becomes smaller at higher magnifications, so the eye must be positioned correspondingly precisely behind the ZF. If the eye is too far or too close to the eyepiece, shadowing occurs in the outer edges of the image. The correct eye relief makes it possible to capture the entire field of view of the riflescope.

Especially with strong calibers, the shot resistance of the optics is an important criterion in the selection.

When the shot is fired, considerable forces act on the telescopic sight. Riflescopes are said to be bulletproof if they can withstand these forces without any changes being made to the housing, mechanics or reticle.

Due to the high quality standards at Vector Optics, the bullet resistance of target optics is guaranteed In addition to the shot resistance of the riflescope, you should also not ignore the assembly used. Of course, we also supply the appropriate mounts for the rifle scope.

The light intensity describes the calculated brightness value of binoculars. The formula for the calculation is: lens diameter divided by magnification, result squared. Example: The rifle scope is given as 4x32, so the calculation is: 32: 4 = 88 x 8 = 64.

The twilight factor denotes the arithmetical value that says something about the ability to see details in poor lighting conditions . The value is usually between 5 (bad) and 25 (very good). The formula for the calculation is: Root of lens diameter times magnification.

Example for a rifle scope specified with 4x32: 32 x 4 = 128 root of 128 = 11.31

Even if a glass looks completely transparent at first glance, some of the light that hits it is always reflected. However, a modern lens consists of numerous lenses, and so the light has to pass many glass surfaces on its way to the eye.

The light reflected from the lens surface leads to unwanted and disruptive effects such as stray light in an optics and reduces them Total transmission, ie how much light actually reaches the eye.

The aim of optics designers is therefore to keep the amount of reflected light as low as possible. This is achieved by a coating on the surface of the lens, the so-called remuneration.

The lenses of the rifle scopes from Vector Optics are manufactured by Schott in Germany and remunerated in a complex multi-layer process (multi-coating ) in order to minimize the reflection for as many wave ranges of light as possible. Many different layers are applied to one another. Since the layers influence each other, the calculation of a multi-layer coating is very complex, but is rewarded with transmission rates of up to 99.9% per lens.

1MOA (one angular minute) is 1 / 60th of an angular degree. With a distance to the target (100m) the adjustment by 1MOA results in an adjustment of 2.91cm.

Explanation:

Target distance = radius == 100m or 10000cm

Circumference = 2 x radius x Pi == 628.31m or 62831cm

1 degree then corresponds to 1/360 of the circumference, i.e. 1.745m or 174.5cm

< p> 1 MOA then corresponds to 1 / 60th of a degree == 0.02908882m or 2.908882cm, rounded 2.91cm

1 MOA == 2.91cm per click on 100m

1/2 MOA == 1.45cm per click on 100m

1/4 MOA == 0.73cm per click on 100m

1/8 MOA == 0.36cm each Click on 100m

Mill (Milliradian) are also angles. Dealing with Mills is equivalent to dealing with MOA or degrees.

Explanation:

When calculating a wheel or a millirad, the distance is described that leads to 2 x Pi x Rad) Circumference of the circle (360 degrees)

Ratio MOA to millirad:

A circle has 21,600 MOA resp. 6283.185 ... millirad (this corresponds to 2 x Pi x 1000) The ratio is consequently 1: 3.437746770 ..., i.e. rounded off corresponds to 3.438 MOA

Calculation: 1 MOA per 100m = 2.91cm3.438MOA x 2.91cm (1 millirad x 1MOA) = 10.00458cm, rounded so 10.00cm. 0.1 millirad is 1cm at 100m

Both the red dot sight and the rifle scope have advantages. The red dot sight is unsurpassed small and light, a weapon equipped with it is therefore extremely manageable. Nothing disturbs the overview less than a red dot sight: When shooting with two eyes open, you have an optimal overview of what is happening: In some situations a safety plus. In addition, red dot sights are robust and significantly cheaper than a high-quality rifle scope: They are therefore ideal as "rifle scope protectors" for use under the harshest conditions.

Red dot sights are aiming devices for short and shortest distances. The area of ​​application of red dot aiming devices overlaps with that of telescopic sights with low initial magnification and luminous dots such as 1 to 4 or 1.5 to 6 times. Only in this context does the question of which is better makes sense. Nobody would think of comparing a rifle scope with 8x magnification and 56x objective diameter with a red dot sight.

However, low-magnification rifle scopes can do just as much of what a red dot sight can do. In addition, rifle scopes offer the decisive advantage that the variable magnification also enables targeted shots at more distant targets. This is considerably more difficult or impossible with the red dot sight. As an alternative, we offer Magnifier which you can simply fold for the red dot sight.

Please read these instructions completely through first before you work through them step by step in practice!

First, the interpupillary distance must be determined correctly, this is with every riflescope with a Range specified. We always choose the center of the area as the scale, with a specified eye relief of 90-110mm, our goal is 100mm in order to be as flexible as possible.

As a result, it is best to be in pairs, as with the weapon at your disposal the position of the glass and thus the mounting point for the assembly must be measured.

Now the lower parts of the assembly can be mounted on the rail To prevent possible shifting on the rail, the assembly of the repeater is always pressed in the direction of the barrel against the next cleat on the rail. In the case of self-loading, the assembly must be pushed backwards, i.e. towards the shaft against the next stud.

Under no circumstances slide one assembly forwards and one backwards, this can inadvertently cause tension and damage the scope!

Next, lay on the lower one Assembly halves a piece of thin rubber, for this purpose cut pieces of disposable latex gloves are ideal. This gives you a higher level of adhesion between the rifle scope and the assembly, which prevents it from slipping. Gluing the rings to the optics is a possibility, but not advisable. Firstly, this is not necessary and secondly, the piece of latex can be removed without leaving any residue. Many assemblies have a small rubber strip in the scope of delivery, this can of course also be used. There are also assemblies that have already glued a rubber strip into the assembly, then this step can be skipped.

Now the rifle scope can be roughly aligned in the assembly and the upper halves of the assembly are slightly screwed on so that our glass can still be moved. Please note that the gap between the mounting halves is about the same.

In order to align the glass with the weapon, you simply help yourself with an object with 2 exactly parallel sides. Each rifle scope has a surface on the underside of the tower section and we tilt the auxiliary object with this surface in order to align it exactly parallel to the mounting rail.

As soon as the glass is aligned, screw the mounting screws crosswise with 1.5- Tighten 2 Nm. Attention: Tightening too tightly can lead to jamming of the adjustment devices or even damage to the telescopic sight, even if no deformation of the tube can be detected from the outside! If such defects occur, the manufacturer's guarantee is not liable.

A rifle scope doesn't just work, it must first be adjusted accordingly by the shooter so that it harmonizes with the weapon. Optimally, the optics are controlled and shot in by the owner himself, because everyone "looks" differently.

Preparation:

- Completely clean the weapon

- Oil-free cartridge chamber

- Clean and de-oiled barrel without any Dirt / bullet residues

- Rifle scope assembly checked for tight fit (often causes of target errors which are not noticed until late or sometimes not at all)

For sighting in is required: < / p>

mandatory:

- Sufficient ammunition with the same lot number (a different batch number can mean a different point of impact with the same load.)

optional:

- Sightmark (this is a cartridge with a laser, this is inserted into the chamber and shows the location of the hit)

- A shooting bench (this is the only way to achieve reproducible results)

As a rule, a rifle is aimed at 100m and then adjusted accordingly via the parallax compensation depending on the distance. However, it starts at a shorter distance. This is expediently done on the 25m lane, because there is no danger of a strongly deviating shot destroying the shooting range, which causes unpleasant follow-up costs. We insert the sightmark into the chamber, align the laser point with the target and adjust our telescopic sight so that the center of the reticle coincides with the point of the laser. Then we remove the sightmark again and carry out the so-called "shot". At least 3, better 5 shots are fired at the same stopping point in order to be able to assess the hit position.

The body and sitting posture must be as comfortable as possible so that the weapon can be handled with almost no tension. In addition, you should sit as upright as possible and adjust the height of the support so that the butt plate can be fully pulled into the shoulder. The recoil is well absorbed. Both arms and elbows must be resting in order to take full advantage of the weapon’s precision. Do not press the telescopic sight or the barrel with your free hand, but support the buttstock if necessary.

For firing the shot itself, you should control your breath and "correctly" pull it off: After a deep breath, exhale halfway again and then to hold breath. Slowly and evenly increase the pressure of the foremost phalanx of the index finger, which is placed exactly from the front on the trigger, until you are “surprised” by the shot. This breath control prevents aiming errors caused by movements that the body automatically makes when inhaling and exhaling.

If the weapon does not shoot where it should, it has to be fired again. To do this, the distance (height and lateral deviation of the group center point) from the stopping point is measured and the telescopic sight is adjusted. You have to turn it where you want the shot to go. If this fits on 25m, we go to the 100m track and repeat the process.

When aiming in, stray circles of a maximum of 5 centimeters should be achieved. The lower the better!

Glass surfaces are sensitive, so you should keep the riflescope as free from dirt as possible. This means that the protective covers should be placed on lenses and eyepieces again and again after use. It should go without saying not to touch the lenses with your fingers. Even "wiping" the lenses with an item of clothing is of course an absolute taboo.

Of course, dirt cannot be avoided, a riflescope is intended for use and not for the display case. Frequent contamination occurs on the eyepiece. Eyelashes, dandruff and grease can contaminate the eyepiece lenses. But dust can also collect on the lens of the binoculars.

Like most manufacturers' riflescopes, the riflescopes from Vector Optics are filled with nitrogen and are therefore waterproof. So simply rinse the lens with lukewarm water under the tap. Dishwashing liquid can also be used for degreasing if you have left a fingerprint. Then just let the glass dry. When you are absolutely sure that sand and dust can scratch your lenses more, polish the eyepieces and objectives with the microfiber cloth provided. Alcohol or a special cleaning fluid can also be used for assistance. Glasses cleaning cloths are sometimes also helpful.

Important: Always rinse the glasses with water first to remove all dust particles, only then work with the cloth.

Fingerprints, Oil or water stains should be removed immediately, because the acids in the skin can attack the coating and the glass and permanent stains can occur. Cleaning with solvents alone often only spreads the dirt. Therefore, these contaminants must be removed from the optical surface with mild soap (no perfumed or moisturizing soap) or another cleaning liquid. The optics are then rinsed with water (ideally distilled water as this does not leave any lime stains) and then rinsed with alcohol.

Attention: As already mentioned, binoculars from Vector Optics are principally waterproof, but you should Do not immerse the glass in water, please only rinse it under running water.
