The optical sight is a special device that is used to increase accuracy. Today it is the best of its kind. The fact is that in the case of using the device, the eyes are accommodated at one distance, which makes it easier to aim the weapon at the target. Use it for weapons began in the 17th century.
This sight has a fairly simple device. One of the main elements of the device is the lens, which consists of two lenses (there may be more). The quality of the sight depends on the diameter of the element: the larger it is, the better the sight.
The optical sight also incorporates a system for converting an inverted image into a direct one. A necessary element is the reticle, thanks to which the weapon is aimed at the target. It is in the same plane with the image of the target, so the eye sees them equally well. It is equipped with a backlight so that when shooting in the dark, the image and markup do not merge. In order for the image and the reticle to be viewed enlarged, an eyepiece is required. It is a multi-lens system. Often it is equipped with a rubber pad that prevents slipping and reliably fixes the eye at the sight.
In order for the weapon to be able to shoot, and the grid and the point of impact of the bullet coincide, the optical sight contains a horizontal and vertical correction mechanism.
The body of the device is made of high strength materials. Modern devices can increase the image by 20 times. Do not lean the optical sight against the eye while shooting, as any weapon has a recoil, even pneumatic. As for mounting the device, it may have lateral support. Dimensions of the device are mostly standard. If a deviation from the standard exists, then it is insignificant.
The optical sight for an air rifle must be selected very carefully. Pay attention to the weight, diameter of the tube and the size of the device. Since airguns are light enough, you should not choose a large optics. You should also pay attention to the control of the adjusting mechanism, the diameter of the outlet of the eyepiece, as well as the degree of image enlargement.
Naturally, the device must be durable and resistant to mechanical damage. Also, the optical sight must be checked for resistance to negative temperature, for tightness. It is necessary to carefully examine the control mechanism of the device.
Naturally, the choice should be made based on the purpose for which the barrel will be used. For example, if you want to shoot at a shooting range or at stationary targets with an air rifle, it is better to choose a device that is capable of enlarging the image by more than 4 times. Moreover, the outlet should be wide enough.
In the selection process, you have the opportunity to look through the scope at a distant object. You should see a high-quality and clear image without any interference. It is such a sight worth acquiring.
