The sniper rifle is a high-precision sniper rifle, which has the characteristics of long range and great power. The character of the sniper is to destroy the target in one shot. However, since the sniper generally has a certain distance from the target, the design is more difficult, and it is necessary at this time Some aids are used to help the sniper complete the design. In addition to the observer to provide information, the sniper sight is also the main auxiliary means. The sight is generally an optical sight to magnify the target, so that the sniper can aim better, but because the target is magnified, and the field of view in the sniper scope is limited, the sniper does not have a reference object to determine the distance of the target, so the sniper rifle The shooting angle is not easy to grasp, so there is a scale mirror between the objective lens and the eyepiece in the sniper scope.
Scale lines and parameters are generally marked on the scale mirror. The scale lines are mainly the distance from the target, the muzzle lift and other data to assist the sniper in shooting. The range of the sniper rifle is relatively long. According to different sniper rifles, the range of the bullet includes bullet speed, effective bullet range and bullet falling speed. The sniper needs to determine whether the shooting method is direct shooting or raising the muzzle to shoot and determine the advance amount. Since the sniper has to fight for a bullet to destroy the target, any parameters must be mastered. In some small places, the sniper needs to adjust the equipment and shooting methods.
Any kind of firearm has its own trajectory. Snipers need to know the trajectory of the firearm very well. In many cases, they need to raise the muzzle to increase the range. Because the sniper rifle has a longer effective range, but the trajectory of the bullet is in The trajectory will begin to change and fall after a certain distance, so the scale line on the scale mirror can help the sniper to judge the distance. The sniper can adjust the parameters on the sniper scope according to the performance of different firearms to adapt to the firearms.
In the improvement of rifle accuracy, sniper rifles with super precision appeared in rifles. Because sniper rifles appeared snipers, and because of the need for better auxiliary shooting, sniper scopes appeared. The performance of weapons has been improved bit by bit, and new combat methods of arms have also emerged. The continuous change of times is also because of the new weapons. In the history of mankind, weapons have spawned wars, and wars have spawned weapons. Civilization promotes war development. , The war has promoted the development of civilization, which has been continuously circulating.
