How to calibrate the laser sight?

Understand the parameters of the scope. Some numbers commonly found on the scope of laser scope sight are the parameters of the scope. For example, 3-9x40, it means that this is a zoom scope with a minimum of 3x and a maximum of 9x, and the lens diameter is 40mm; For example, 4x40 is a fixed-magnification scope. The magnification is 4x and the lens diameter is 40mm. There is also our most common distance compensation knob adjustment knob located directly above, and the wind deflection knob is located on the right. (When you turn the knob, whether it’s the one on the top or the side, the offset after a click is 1/4 inch adjustment. The click value is 1/4 MOA (1 inch = 2.54 cm), and the focus is recently adjusted 10Y (1Y). = 0.9144m, that is to say 10Y ≈9.1m, 1/4 click value means that the impact point of 100 yards has moved 2.54/4=0.635cm). If adjustment is required, the process is also very simple. If the impact point is at the center of the cross Below, the upper adjustment button adjusts the appropriate amount along the arrow up direction; if the popping point deviates from the right side of the cross line, adjust the left and right wind deflection adjustment buttons laser scope sighter along the arrow left to adjust the vertical and horizontal adjustment components of the reticle. vice versa.

When adjusting the aiming point and the impact point, you must first determine an aiming distance. If the distance to the target is preset to 10 meters, a set of 3 test calibrations, then a total of four steps.To find out the actual impact point, first place the target map or target. I suggest that novices should practice with the target map first to be clearer and easier to get started, and hit the center 3 times.Find the center of the shooting point and aim at a distance of 10 meters. If you shoot three times and you are not in the bullseye, then you need to correct the scope at this time. Find the three points you just shot three times, connect them, and find the center point.
Measure the vertical distance between the actual shooting center and the target center. If the horizontal distance between the center of the triangle and the center of the target is 40.74mm and the vertical distance is 45.66mm, as mentioned above, the top, bottom, left, and right knobs of the scope are marked with 1/ 4''100YD, a quarter of an inch is equal to 6.35mm. In other words, the horizontal direction is shifted to the right (40.74÷6.35) X10 = 64.15748 divisions (here 10 refers to the aiming at 10 meters), adjust the left and right wind deflection knobs, and rotate about 64 divisions in the L direction, that is, click 64 under. In the same way, we can conclude that the vertical direction is deviated downward (45.66÷6.35) X10 = 71.90551 divisions, adjust the knob up and down, rotate 72 divisions in the UP direction, that is, click 72 clicks. Usually by this step, the basic calibration calculation is completed, and there is still the last step of correction. Adjust and test again three times at the aiming distance of 10 meters. Because there is no careful measurement and adjustment, there is basically an error, but the error should be about 1mm, and then adjust again, that is, rotate one square up, and after one square right 10 meters can do the double point. At this time, shooting again should aim at the bullseye. If you want to measure the distance more accurately and simply, you can choose a distance measuring scope. This type or Hunting Green Laser Sight Dot does not require a ruler to measure, and does not need to have a reference object. It basically measures the distance automatically without error, especially when facing movement. The most effective target or hunting is when the distance is not easy to estimate. Like general shooting range or fixed shooting, there will be reference objects, or pre-measurement and so on. It still depends on what environment you do.

To eliminate parallax, if you want to aim accurately and shoot accurately, you must first eliminate the parallax of the optical sight, that is, reset the parallax to zero, so as to ensure that when you are aiming, the position of the eye is still the same when the eye position changes slightly. Accurately, only then can the aiming point and the impact point of the scope be calibrated to coincide as much as possible! The scope cannot be attached to the eyes like a telescope. The correct way to use it should be to leave a distance of about 4~7cm, because there is recoil when shooting. The recoil will cause the shooting equipment and the to collide with the rear sight, and it is easy to knock the eyes. Therefore, the general laser sighter bore sight will be designed with a reasonable exit pupil distance.
If you want to measure the distance more accurately and simply, you can choose a distance measuring scope. This type of dot sight scope with red laser does not require a ruler to measure, and does not need to have a reference object. It basically measures the distance automatically without error, especially when facing movement. The most effective target or hunting is when the distance is not easy to estimate. Like general shooting range or fixed shooting, there will be reference objects, or pre-measurement and so on. It still depends on what environment you do.
