7.62 mm live ammunition was fired from the muzzle.

40mm anti-personnel grenade 8 1-bar rifle is fired from the muzzle with 7.62mm live ammunition, which is a classic automatic rifle system in the domestic rifle family. Its powerful combat capability is recognized by all: Grenade is used to kill enemy groups and the effective force of tanks and armored vehicles within 290 meters, to accurately shoot a single target within 400 meters, and to shoot aerial planes within 500 meters. Even if the warhead is at 1500 meters, it still has lethality.

One of the most striking technical features of the fighting power of 8 1 bar is that although its caliber is 7.62 mm, it can directly fire 40 mm rifle grenades from the muzzle with live ammunition, and there are many types of rifle grenades launched, mainly including 40 mm anti-personnel rifle grenades, 40 mm armor-piercing rifle grenades and 40 mm multi-purpose rifle grenades.

It can be seen that 8 1 bar has strong point-to-surface killing ability. In addition to firing rifle grenades directly through the muzzle, domestic 8 1 bar can also be hung with Grenade launchers under the barrel. The 40mm anti-personnel rifle grenade is an ordinary rifle grenade system of 8 1 bar. It has a diameter of 40mm, a length of about 290mm, a weight of about 0.35kg, an initial velocity of about 60m per second and a maximum range of about 290m.

About 400 effective killing fragments can be produced in the range of 290 meters, and the effective killing radius is 14 meters. When 8 1 bar fired 40 mm anti-personnel rifle grenades, it used Type 56 7.62 mm ordinary ammunition. When 40 mm anti-personnel rifle grenades are fired with live ammunition, 8 1 bar will not produce any post-sprayed substances.

Generally speaking, the 40mm anti-personnel grenade made in China by 8 1 bar has the following three technical features.

First, its warhead contains 400 prefabricated fragments of steel balls.

This is the distinctive technical feature of the domestic 8 1 bar 40 mm anti-personnel Grenade. From the structural composition, the 40 mm anti-personnel rifle grenade of 8 1 bar is mainly composed of warhead, tail, fuze and caliper, and the key components in the medium term are warhead and tail. Its warhead is equipped with 400 steel ball prefabricated fragments and high-energy explosives, with a diameter of about 3.5 mm, which can kill living targets within 290 meters.

Secondly, its tail is cleverly designed, consisting of tail pipe, bomb collector and tail wing.

This is another distinctive technical feature of the domestic 8 1 bar 40 mm anti-personnel Grenade. From the structural composition, its tail mainly includes three parts, namely, tail pipe, bomb collector and tail wing. The mid-term tail pipe is used to accommodate the bomb catcher, and its function has two aspects. One is to put a Grenade in the muzzle.

Then the pressure of gunpowder gas and the impact force of the projectile are transmitted to the anti-personnel Grenade; The bomb catcher is mainly used to absorb the warhead, obtain the impact energy and ensure that the warhead will not damage the warhead. The function of tail wing is relatively simple, and it is mainly used to maintain the flight stability of rifle grenades.

Third, its launch principle is unique.

The working principle of 8 1 bar launching 40mm anti-personnel rifle grenade is roughly as follows: after pulling the trigger, the bullet on the bullet is absorbed by the bullet catcher in the tail pipe of the grenade launcher, and the anti-personnel rifle grenade obtains its initial velocity by the pressure of gunpowder gas and the impact ability of the bullet; Then the instrument fell in front of the gun. Fuze is disarmed by recoil, which makes the rotating body rotate.

At this time, the assistant's needle pierced the fire cap in the back seat and ignited the delay drug, thus detonating the anti-personnel Grenade. At the moment of collision with the target, due to the huge resistance of the anti-personnel grenade, the needle hit the detonator and detonated the warhead, so that the prefabricated fragments of steel balls in the warhead spread in all directions at high speed, killing the surrounding targets.
