With different types of weapons, you need to use different sights. There is a huge variety of sights available to choose from. While every sight has its own uniqueness, you can use only one at a time. Thus, you need to choose the one that would provide you with the most accuracy possible.
Though gunsights have to serve the purpose of providing you with the accurate aim, not every device is fulfilling it. Among all the various types, telescopic sights can provide you with the most accuracy, thus can be the right choice for you to make.
However, before you go and buy one for your firearm, you need to know about the different types of sights available. Just because a sight provides good accuracy does not mean it is for everybody.
Various Types Of Sights That You Need To Know About
All the sights or optics help you aim more accurately while using a firearm. Thus, it is essential that you know the various types before choosing the right one for yourself.
- Iron Sights
Iron sights are the first kind of sights to be ever used. So if you want to use something that can remind you of the good old days, it is the one for you. Previously there were no aiming devices, which often hindered the aiming of the shooters.
However, as the firearm started to evolve, the need for a device to assist in accuracy started increasing. This need led to the invention of Iron sights. Many people still associate this invention with rifling, as it provided nothing but accuracy.
In iron pieces, the two components must line up with each other. These two components are the front aiming piece and the rear aiming piece. While talking about sidearm, most of them depend upon this sighting device. So it doesn’t hurt to keep one as a backup with them being simple to use.
- Telescopic Sights
Sighting instruments that follow the principle of refracting telescopes are termed telescopic sight. Many people use the term scope to address these sights, so don’t be surprised to hear somebody call them scope.
If the iron sight was the first sight ever made, these are the first optical sights. With a reticle mounted on a focally appropriate position, you get the accurate point of your aim in the optical system.
As the first-ever appearance of these scopes dates early 18th century, they were in use in both world wars. However, then they were more commonly used on sniper rifles. Nowadays, you can see them being used with assault rifles, DMRs, and sniper rifles. Combining telescopic sight with infrared optics has proven to be the best one.
- Reflex/ Reflector/ Red Dot Sight
Reflector or reflex sight is an optical sight that projects an illumination of the aiming point. This point is superimposed on its field of view and is usually presented by a dot. You can look through the partially reflecting element made of glass.
The principle used in their performance is the simple optical one. It is the reason why the dot appears to be in front of you while being at infinity because it is at the focus of the lens. As you can get the idea from its name, it does provide you faster shooting experience.
The dot is one of the most preferred sights, thus making them a choice of many people nowadays.
- Holographic Sight
Holographic diffraction sight or the holographic weapon sight does not offer you magnification. You get to see an image, which is a holographic reticle image, on the felt of view but with a distance. An optical window made of glass allows you to peep through. This window contains the hologram, and the laser diode illuminates it.
This type of gunsight is prevalent in the modern armies of today. Holographic sights generally work well with submachine guns and assault rifles. These also go well with the AKs and are used for the same weapon in the military.
- Thermal Optics
Thermal weapon sight is an instrument that combines an aiming reticle and a compact thermographic camera. You may hear people use different terms to talk about these, like thermal imagery scope, infrared or thermographic weapon sights.
Regardless of the name you choose to address these with, these will be serving the same purpose. They possess the characteristics to be used in the nighttime. They are widely known for being night vision optics. They also help you look through the smokescreen or any other objects of similar properties.
With such features offered by these sights, they are even considered hybrid sights. The name indicates that these have properties of many sights within a single type.
Which Type Of Sight Is Most Accurate?
Now that you know about the different types of sights used worldwide, it is time for you to know which one will be the most accurate one. The accuracy of the telescopic sights is the best among the variety mentioned. Even for the long-range, you can have the accuracy.
It is based on the refracting telescope, which offers you a precise focusing point. There are certain patterns of the graphic image in the optical system. Such a sight can be utilized on all the systems. Though they are mainly preferred on rifles, they can still provide precision on each of them.
Even some new models of this sight come with flashlights, lasers, or night visions. Finally, you can find one that offers the quality you are looking for without compromising the accuracy.
Things You Should Know Before Choosing The Sight
If you are looking forward to purchasing a good sight, here are a few things that would demand your attention. For example, if you are looking to buy a telescopic scope, then there are optical parameters that you need to consider.
Magnification matters a lot when you are hunting or shooting. Some sights offer you higher magnification, while there are some that offer none. The magnification calculation is a bit more complex on an excellent sight device like a telescopic one.
When the focal length of both the eyepiece and the objective lens is divided, the ratio gives linear magnification. The magnification value tells you about the closeness you will feel towards the object. If the magnification is lower, then there is more chance of shaking. For the larger value, the field of view is smaller.
- Diameter Of The Lens
The diameter of the lens determines the amount of light that will be gathered from the image. Usually, the value is in millimeters, and you can choose the sight according to your demand.
- Field Of The View
It is also a measurement that will help you know better about the effectiveness of the sight you are using. Generally, this factor is based on the design of the sight; thus, you would need to pay some attention to it.
There are two ways of calculating it. The one is the linear value that tells you about the width of the area seen at 100 meters. The other way is to take the angular value. It is generally determined in degrees.
- Exit Pupil
The objective lens gathers light to concentrate in a beam in a telescopic sight. There is an exit pupil that can help you achieve the brightest image. If the diameter of this pupil is kept the same as the fully dilated human iris, then the maximum light gathering is done, giving you the brightest image a sight can.
For determining the value of the diameter, you need to reduce the age by 7 mm. it will give you an idea of the dilated iris. You may be wondering why this is necessary. If the light falls out of the pupil, the rays do not provide your brain the information about the image. Hence, the intensity of the image reduces.
- Eye Relief
While looking for a device that will be closer to the eye, it is necessary to consider this factor. If you see the image more closely, then it will strain your eyes. The same goes for the farther distances. So it is crucial that you pay attention to the distance between the lens of the eyepiece and the eye point.
You must know that the greater value of focal length provides greater eye relief. Generally, for a telescopic sight, you can find eye relief ranging from 25 mm to 100 mm. you can choose the one that suits you the best. As for the handguns or scout rifles, you would require more eye relief.
A high value of eye relief will make sure that there is no worry of recoil damage, especially for the eye. Even if you are learning your way through this sight, his value will ensure that you do not end up hitting yourself in the eye.
With so many sights available today and each having its specific characteristics, it may become difficult for you to choose the right one. However, if all you want is accuracy, you can go with the telescopic sights. Though they offer you great accuracy, you need to be more attentive to the specific factors while purchasing them.
