Ask some basic concepts about guns.

1. Caliber refers to the diameter between the rifles of the barrel, and 8 1 is 7.62mm..

2. Magazine capacity is the number of bullets, 8 1 rifle is 30, machine gun is 76, 77 pistol is 7, 79 micro-impact is 20.

3. The firing rate is the number of shots per minute.

The weight of 4.8 1 is 3.8KG

5. Bullets: 56 ordinary bullets of our army, about 20-30 grams.

6. The firing rate of a bullet should refer to the speed when the bullet leaves the chamber and the speed when it flies after leaving the chamber. It seems that 8 1 is 750m/ s. It is hard to say that it is affected by weather and other factors when flying. But the range of 8 1 is about 2000m m. Generally, the armed police are controlled within 100m-300m during training, and the old field is more than 200m.

7. Firepower is lethality. 8 1 There is basically no ballistic height within the range of 100 meters, and you can hit wherever you point. Theoretically, it can penetrate 6 mm thick steel plate, 10 cm thick wood plate and 30 cm thick soil layer, which is also lethal. Air explosive bombs can hurt people within 3 meters.
