The principle of the sniper between the sniper and the working principle of the sniper rifle

Hello bro. The so-called gap sniper is to aim in the gap between two buildings.

For example, on top of the sand and ash a-door box, there is a slope that aims at T's house through the crack in the door.

There is also the gap between the high protruding box and the wall at the B bag point, aiming at the passage of the B hole.

There is also a sniper point on the slope of the T house in the gap between them.

Thank you.

Basically, blasting the middle of the map, you need to suppress it with a special hand when you play, as well as observe the opponent's movements, and report points in time.

The original sniper rifles were selected from ordinary rifles with relatively high accuracy, and were equipped with aiming equipment to be used as sniper rifles.

The automatic principle of light ** is more complicated, not what you imagine if you want to become a burst can be realized, the realization of automatic firing requires a complex structure, which can easily lead to a decrease in shooting accuracy, and at the same time, automatic shooting is not convenient to adjust the design state of the shooter. In addition, sniper tactics require a single shot to kill the enemy, and in many cases firing an extra shot means that the shooter is in danger of being discovered.

However, there are also some sniper rifles that can achieve automatic shooting, such as PSG-1, SSG-550 and other more famous sniper rifles.

Another point is that for large-caliber sniper rifles and anti-materiel rifles, it is simply impossible to use automatic mechanisms, and such recoil is not controllable by manpower.

Spot sight optics.

There is no magnification system and no inverted lenses. The basic structure is composed of an optoscope, an aiming marker board, and a light-emitting unit.

The concave surface of the reticle is coated with a layer of anti-optic film, and the reticle is a metal sheet with a thickness of about mm, on which there is a diameter anvil hole or ring, which is just located on the focal length of the concave surface of the refine. The light from the light-emitting unit is reflected through the anvil through the light analyzer and enters the pupil of the eye as a parallel light. The shooter then sees a point of light at infinity, and can also aim at the target through the lens as long as the point of light overlaps the target.

After the rifle is attached to the scope, it needs to be corrected so that the aiming point coincides with the target.

Window sight optics.

The whole optical system is moved in the way, and the adjusting bolt is used to drive the whole optical system to swing in the horizontal and vertical planes to achieve the purpose of correction.

Straight-barrel sight optics.

Adopt the mode of changing the relative position of the lens and the aiming marker, the lens is fixed in a swing tube, and the adjusting bolt can make the swing tube drive the glass-analyzing lens to swing relative to the aiming marker, so that the relative position of the aiming light point and the target is changed to complete the correction.

I also had this problem when I was a kid.

That is true. The trajectory of the bullet is a parabola (not a parabola with a small radian of a quadratic function), while the imaging trajectory of the scope is a straight line.

a parabola; A straight line and a parabola can have 2 intersections at most, which doesn't need to be explained...

So there is no need to adjust the sniper scope at these 2 points, that is to say, at these 2 points, it is a cross sight**bullet hit**.

Between the two points, the bullet impact point is lower than the cross aiming point, and outside the two points, the bullet impact point is higher than the cross aiming point, which needs to be adjusted by the shooter himself through the usual familiarity with the sniper rifle.

For example, the two intersection points of the M16 aiming trajectory and trajectory are 25 meters and 400 meters respectively, aiming at one point within 25 meters, aiming at the target between 25 meters and 400 meters, and aiming at the target at 400 meters away.

Got it? If you're like me, knowing this question and then having to ask another question, "How do snipers know how to adjust their scopes so that the sight is aimed at the point of impact?" ”

Then please refer to it.

Typing tired - -

The simplest explanation is that the trajectory of the sight and the bullet is not absolutely parallel, for example, at a target 1000 meters away, adjust the scope to a distance of 1000 meters. The trajectory of the bullet intersects with the center extension of the reticle! So judging the distance in sniper combat is very important!

To shoot at a long-range target with a sniper rifle, the first thing to say is the trajectory of the bullet, and by calculating various parameters, the distance from the straight line of the barrel extension when the bullet reaches the target is obtained. Actually, the lens group where the reticle (i.e. cross) in the scope is located, and there are knobs on the barrel with scales, for example, 10 meters, 20 meters. 500 meters, 600 meters, after knowing the target distance, turn the knob so that the sight line and the barrel line intersect at the target, and then through another knob plus the distance of the bullet from the barrel extending straight down, you can hit.

For example, the M82 sniper rifle shoots at a target at 1000 meters in a standard environment, the bullet falls exactly 1 meter from the barrel extension, and the specific steps are: 1, adjust the first knob to the 1000m scale, then adjust the second knob to the 1000mm (equal to 1 meter) scale, 2, move the reticle to the target. 3. Pull the trigger.

To answer this question, we must first talk about the trajectory of bullets, and the trajectory of all bullets fired by guns at present is not a straight line, but an unequal parabola. The reticle from the human eye to the reticle is a straight line, so theoretically the place where the bullet hits is the point where the parabola drawn by the bullet intersects with the man's line of sight. The scope is not parallel to the barrel, but only approximately parallel, so to hit targets at different distances, the aiming point of the scope should be raised or lowered accordingly.

The gun has an arc, and the sight is measured.

After measuring the wind speed and direction, adjust the knob on the sniper scope, which does not necessarily have to hit the underside, but depends on the trajectory of the gun and the angle of shooting.

The bullet trajectory is an unequal parabola.

Calibration- I don't know what this is the basic principle.

It's a bit like the Model 653 submachine gun from Mity. If you want to talk about sniping, it is a little bit similar to the ross1914 that everyone takes, and it is not at all like a regular sniper.

Sniper scopes, convex lens imaging, and reflection of light. Ballistic calculations, aerodynamics.

The first thing to say is that the gun is not aimed in the process of movement, and the AWM series is the same, the sniper is to use this principle, it seems that it is not aiming, but in fact, it uses the principle that the gun is not aiming in the process of movement, and the trajectory deviates, so there is some probability of hitting someone, to put it bluntly, it is a kind of Meng.
