If we perfect the laser pointer weapon, can the sniper reach the target of 5 kilometers or even 10 kilometers? The art of long-range shooting is one of the only things in the gun field that has not been destroyed too much by technology. Even if your scope can see more than 10 kilometers, and your gun has a bullet that can fly that far, in the final analysis, it all depends on the person behind the butt.
One of my grandfather's military buds was a legend holding a spear, at least for me. I used to spend a lot of time with them in an open range. One of them, even with a scope without professional magnification, this person can shoot a good hit rate from a distance of about two kilometers. This is because he is a professional gunman. All this has to do with your senses as a shooter.
You have to consider the wind speed, even if it is not an accurate estimate, you have to consider the speed at which the bullet lowers its altitude as it moves towards the target, even within some distance, or at least I was told that the Coriolis effect started to work, so you This must also be taken into consideration. So, unless you mean to return the bullet laser, the answer is—the quality of the gun depends on its shooter.
Why are not all guns equipped with laser pointers as standard? It seems that this will be a relatively easy feature, as long as it can be easily turned off, there will be no downside. Laser sights have some disadvantages: weight-they may be very light, but the battery is not, they will change the balance of the gun. No need-for short-range pistols (this is what the pistol is for), iron sights are easier to use. For rifles, the scope is better.
Adjustability-if you install a laser on a rifle and aim at it, such as 100 yards, how do you compensate for a 200 or 300 yard shot. Lack of visibility at a distance-you cannot easily see the laser within 100 yards. Precision sight-laser is a precision device. Rifles and pistols are not.
They can be seen on the other side-for combat soldiers or hunters, it is best not to notify your presence before you shoot. If you can see your green laser pointer, other people can also see it. Well, with all these shortcomings, why do we see laser sights in the movie? Because they can show that this person has many guns pointed at him without removing the camera from him.
