A red dot sight is a non-magnifying reflecting device which is mounted on guns for accuracy in aiming targets. The red dot sight gives the user an aiming point in the form of an illuminated red laser beam. Usually, a red dot sight comprises a red colored light emitting diode (LED) which generates a red colored pinpoint when observed from the eyepiece. Since the red dot sight is fixed on the weapon, the aiming point moves with the weapon, making it easier for users to aim at their target.
Red dot sight devices find its use in many areas like hunting, shooting, military etc. Besides its application for the weapons, red dot sight devices are also used for observation purposes by mounting them on cameras, because of which the users are entitled to click photographs easily. Red dot sights also find their use in telescopes, where they are used as a secondary scope for finding and observing objects located far away.
How to choose a Red Dot Sight?
There are a few factors which help in deciding the quality of any red dot sight. These factors have been discussed in detail in the following sections.
Reticle size is found by the thickness of the red dot as visible to the user. This thickness is dependent upon the maximum possible distance for which the red dot sight is being used, i.e. longer the range, more will be the thickness of the red dot.
Being measured in minutes of arc or minutes of angle (moa), it is very crucial that the red dot appears accurate to the user, irrespective of the environmental conditions. The reason we are mentioning the environmental conditions is that, for some of the laser-based red dot sights, the device fails to operate at low temperatures, due to which there are chances that the dot may appear blurred to the user, resulting in inaccuracy while aiming at the targets.
The smallest thickness of dot achieved till date is 1 moa, which is certainly a disruptive achievement considering the fact that most of the red dot sights have a reticle size of approximately 4 moas.
There can be many variations possible while manufacturing a red dot sight device. For example, there are red dot sight devices available in the market in which the users are able to vary the thickness of the red dot, depending upon the aiming distance. Also, there are some products having crosshairs for the user to aim easily and accurately.
Hence, with so many variations in reticle size available in red dot sight devices, it can be considered as a crucial factor while purchasing the red dot sights.
The provision of battery backup in red dot sight devices is a very important factor in determining the quality of a red dot sight. If your red dot device is not powered, the user will not be able to see the dot.
Drainage level of red dot sight batteries depends largely upon the environmental conditions. For example, the moist and cold atmosphere of forests leads to rapid battery consumption. Varying from one product to another, the battery life can also vary. But in order to ensure longer life of the red dot sight, it is suggested to switch off the red dot sight when not in use. This helps in improving the life of the red dot sight while maintaining the beam strength. So, while buying a red dot sight, choosing a product with longer battery life is a must.
Co-witnessing is another important factor which is widely applied to red dot sights meant to be used for military purposes. Co-witnessing is a feature which allows the user to visualize both the red dot sight as well as the iron sight. Iron sights are considered as a backup vision in situations when the red dot sight goes out of order.
There are red dot sight products available in the market which are compatible for functioning in dim lighting levels. In such cases, all the user needs to do is to fix a night vision riflescope or monocular before the red dot sight. This allows the user to use red dot sights during low lighting levels.
The reason why a riflescope or monocular is used is that any source of light, when viewed through the monocular will magnify multiple times, and can lead to vision blindness to the user. In order to avoid this situation, the night vision compatible red dot sights are used, which enables the user to see the dot at very low brightness level in darkness.
So, co-witnessing is an important factor to be considered while purchasing any red dot sight device.
Recoil Load bearing tendency
Since all red dot sights are reflex vision devices, it is very critical to ensure that the red dot sight equipped on the firearm is capable of handling the recoil force generated due to heavy loads, especially in case of a shotgun.
When the recoil is generated by the weapon, the user has to ensure that the electronic circuitry of the red dot sight does not get damaged and that it functions properly even after bearing the recoil. There are chances that the calibration of the red dot sight may get disturbed, or it may malfunction as well.
Hence, the durability of the red dot sight, and its ability to easily bear recoil force produced due to heavy loads being fired play an important role in describing the quality of the red dot sight product.
One of the major objectives of any red dot sight product is to enable the user get a sharp sight of the dot, as well as the target. This requirement is to be fulfilled even under low lighting conditions, specifically for night vision compatible red dot sights.
Therefore, lenses which allow maximum light transmission through them, while being resistant to damages like scratches and abrasion are highly preferred. Due to this reason, lenses form another important factor in deciding the overall performance and quality of the red dot sight product.
As we discussed moa above, it is very important to achieve the desired measure of the angle. Usually, all the red dot sight devices are designed and manufactured to give the users maximum possible aiming over a distance of 100 yards.
Therefore, having a 1X sight while keeping both the eyes open is a major requirement. This is especially critical for shotgun sights used on tactical rifles.
Purpose of Use
While purchasing a red dot sight, it is very critical that you understand the purpose of buying the product. Usually, dot sight products priced below USD 50 are not resistant to large recoil forces, and hence are suitable only for lighter firearms like pistols etc.
Red dot sight products priced above USD 100 are considered to be good in quality and durability and are ideal for use with shotguns. So, this factor greatly solves the confusion regarding the ideal red dot sight for a shotgun or any other firearm.
Now that we have discussed the factors affecting the quality and performance of red dot sight devices, we shall now discuss the top rated products on the internet along with their pros and cons.
