There are generally two methods of adjustment, one is adjustment with focal length, and the other is adjustment without focal length, that is, adjusting the zoom sight and the fixed zoom sight. When adjusting the zoom sight, we can directly adjust the focal length of the sight. Don't be hasty when adjusting, slowly adjust until the crosshair of the sight no longer moves with the movement of the eyes; Adjusting the fixed magnification sight is a bit troublesome. First, remove the outer ring of the sight, and then find the inner ring. The inner ring is easy to distinguish, and the one with the outer thread is the inner ring of the sight. Gently rotate the inner ring to adjust it to the desired level. After the parallax is reset to zero, install the outer ring gently to avoid damage to the sight. Adjusting the parallax of the sight to zero can reduce the errors generated during shooting and improve the accuracy of shooting. For experienced players, adjusting parallax is very easy, but sometimes it can be a bit difficult for beginners. Friends who are new to the sight glass don't need to be nervous. As long as they learn, ask, and practice more, they can naturally become proficient and easily reset the parallax of the sight glass to zero.

To calibrate your sight, you need an adjustable infrared targeting device, which can be purchased at regular sight shops and is very cheap. When choosing, we should pay attention and try to choose those with guide rails that can be added directly, which is very convenient. When installing the sight on the gun, it must be ensured that it is parallel to the barrel. The first thing to do when installing the sight on the gun is to calibrate it. The foreigner's name is ZERO. The adjustment of the knob on the aiming lens is required to achieve alignment with the impact point.

Find a suitable place for testing, as the designed equipment has a certain degree of harm, so we need to calibrate it in a quiet place with fewer people, and the calibration distance should not be too fixed. Calibration should be carried out from 10 meters to 100 meters.

The special sight line design in the sight glass can be used to estimate the target distance or take the shooting lead. Usually used by snipers. The so-called 'mil' is milli radians. A circle is equivalent to 6.283 radians, and a milliradian angle is equivalent to 0.0573 degrees. Since it is an angle, like the application of MOA, it can be used to represent a specific height or width at a certain distance. Example: tan (0.001 rad) * 1000=1.000000 3333, so one milliradian at 1000 meters is equivalent to a height/width of 1 meter. Due to the convenience of conversion, the military sight is based on milliradians, and precise scales composed of dots or ellipses are added to the aiming line. The shooter can easily estimate the distance of the target. The person scale of 1.5 meters in the figure is 5 mil, and the distance is estimated to be 300 meters.
