Global Wasteland: Upgrade from Abandoned Base

Chapter 164 RPG7
In the rear part of the RPG is a conical tube linked to the launch tube by a knob.

This is used to guide the gunpowder gas out of the rear of the launch tube more safely when firing.

And a guard plate is designed at the rear end to prevent mud, sand and other debris from clogging the tail nozzle.

This is basically the main structure of the launch tube.

The handguard and the cone at the rear are detachable for easy transportation and portability.

What Yue Chi likes the most is that this RPG is a sniper rifle!
At the front of the launch tube is a foldable front sight.

After opening it, Yue Chi found that the columnar sight structure was used here.

Cooperate with the foldable notched rear sight located above the rear grip for aiming.

Among them, the aiming distance can be adjusted through a slider.

It has a sight, a long range, and a large caliber. Isn't this a sniper rifle! ?

In front of the rear grip of this RPG7 is the trigger mechanism. The trigger mechanism of the RPG7 is quite special, and it adopts a structural design that is integrated with the grip.

The firing mechanism of the trigger is designed on the upper part of the grip, and the interior is composed of a rebound firing pin assembly located in the firing pin seat chamber.

In other words, its firing mode is a lever-type locking mechanism.

After the rocket is in place, the trigger will be disarmed.

At this time, depressing the trigger will drive the lever type rebound firing pin assembly to fire a link assembly located on the launch barrel.

And this component just corresponds to the primer of the rocket inside the launch tube, so the rocket propellant can be fired from below through this structure to launch the rocket.

The front end of the RPG7 launch tube has a positioning pin notch.

Only by aligning with this gap when installing the rocket can it be installed normally.

After aligning with this gap, the primer of the rocket in the launching tube will be aimed at the firing pin, so it can be fired through the launching mechanism smoothly.

However, Yue Chi vaguely remembered that the mechanical sights that come with the RPG7 were not accurate enough and needed to be adjusted.

As a result, when the target is found, if you want to launch it, you must manually aim it.

But when he is ready, he will find silently that the target has gone far away.

Of course, there must be another situation, that is, you have already flown high.

In response to this situation, Yue Chi recalled that this thing should also be equipped with an optical sight that combines aiming and measuring. This sight has a magnification of 2.7 times and a field of view of 13°.

I just don't know if this is worn or not.

Presumably the system said RPG7 set, it should have everything.

So Yue Chi began to rummage on his bed.

That's right, after Yue Chi had breakfast

Finally, he found an optical sight the size of half his fist.

After installing the optical sight, Yue Chi started to fiddle with it.

Anyway, I didn't fire the cannonball now, even if the trigger was triggered, it didn't matter.

Putting his big eyes up, Yue Chi used the horizontal line on the reticle of the scope to measure and aim at the things outside the second-story fortress.

Corresponding to different ranges, and corresponding to different scales according to the different shells equipped.

Among them, the scale at the bottom corresponds to heavy artillery shells, corresponding to 200 meters, 150 meters and 100 meters from bottom to top.

In the upper grid scale, the left side corresponds to the light warhead, which corresponds to 200 meters, 300 meters, 400 meters and 500 meters from top to bottom.

The right side corresponds to the medium-sized warhead, which corresponds to 100 meters, 150 meters, 200 meters and 300 meters from top to bottom, and the slash scale in the middle can be used for distance measurement.

This system has an obvious leather style and can be quickly disassembled and installed.

This is also an important reason why Yue Chi can barely operate as soon as he gets started.

And it is so convenient, and it is also convenient for timely and precise firepower output on a rapidly changing battlefield.

With such precision, Yue Chi is more sure that this is a sniper rifle.

In terms of ammunition, the RPG7 is a recoilless weapon.

When fired, the forward momentum of the projectile is balanced by the momentum of the propellant gases ejected from the rear of the barrel.

其炮弹主要采用的是PG-7VM 70毫米破甲弹、PG-7VS 73毫米破甲弹、PG-7VR双64毫米/ 105毫米破甲弹和TBG-7V 105毫米温压弹等等。

But I currently only have PG-7VM 70mm armor-piercing ammunition, and there are only fifty of them.

Holding this 70mm armor-piercing shell in his hand, Yue Chi suddenly remembered the exclusiveness of this shell.

That is, they all have two levels of power.

The first stage is the propellant that is rolled together with the tail fin in a green paper tube and screwed behind the projectile.

Its main role is to give the grenade initial velocity.

After the projectile leaves the launcher, there is a complete solid rocket in the middle of the projectile.

This is used to accelerate the speed of the gun body. The rocket nozzle is designed in the middle of the body and protrudes outward.

Start to ignite when the projectile flies about 25 meters away from the launch tube.

The design of the RPG7 ammunition, such as recoilless gun + rocket range extender, is very rare in individual rocket launchers.

This power design allows the maximum speed of its shells to reach about 300m/s.

The initial velocity of the muzzle is only 115 m/s, so it can have an excellent range while ensuring that the propellant is not so large.

So the maximum range of the shells fired by this RPG7 is 920 meters to 1000 meters.

The timed self-destruct fuze of its shells is 4.5 seconds, which can deal with all kinds of different armored vehicles.

If even the armor ability is so powerful, Yue Chi feels that it shouldn't be a big problem to use this thing to beat those demon soldiers.

However, the armor-piercing capabilities of this weapon vary depending on the distance to the target.

Under normal circumstances, the penetration depth of homogeneous armor within the effective range is between 350mm and 400mm.

This is 35 cm and 40 cm. No matter how thick the devil's skin is, it should be killed by the blast.

The ammunition of RPG7 adopts a two-stage structure, so it can fire larger caliber shells.

This is why there were so many rocket shells before.

Therefore, it is only necessary to carry different types of shells to deal with different targets.

Small rockets hit zombies, large rockets hit demons.

Yue Chi believes that only enough logistical ammunition is needed, and an RPG7 combat unit can provide sufficient fire support.

This thing has durable leather and fierce firepower, so it's good to carry it with you.

Therefore, Yue Chi didn't even think about the ownership of these two RPGs, and directly allocated them to his own guards.

Of course, this kind of good thing should be used by his own guards.

After all, nothing is more important than your own safety.

In addition to these ordnance resources, Yue Chi also obtained a large number of daily necessities and common items.

What mineral water, compressed biscuits, canned beef, canned fruit, sanitary napkins, toilet paper, and even some cloth have been obtained.

Yue Chi prepared to take out two-thirds of these materials and weapons and hand them over to the Ordnance Institute and the Logistics Department.

After all, the development of the base still needs a lot of materials.
