How Do Fully Automatic Guns Work?

Fully automatic guns are a type of firearm that can fire multiple rounds without requiring the user to manually cock or reload the weapon after each shot. These guns are designed to automatically eject the spent cartridge and chamber a new round, allowing the user to continuously fire the weapon without interruption. In this article, we will explore the mechanics and principles behind fully automatic guns.

What Makes a Gun Fully Automatic?

A fully automatic gun is typically defined by its ability to fire multiple rounds with a single trigger pull. This is achieved through the use of a selective-fire mechanism, which allows the user to switch between semi-automatic and fully automatic firing modes. In semi-automatic mode, the gun fires one round with each trigger pull, while in fully automatic mode, the gun fires multiple rounds with a single trigger pull.

Key Components of a Fully Automatic Gun

A fully automatic gun consists of several key components that work together to achieve automatic firing. These components include:

• Receiver: The receiver is the main body of the gun, which houses the other components.
• Bolt carrier group: The bolt carrier group is responsible for moving the bolt back and forth, chambering new rounds, and ejecting spent cartridges.
• Bolt: The bolt is the moving part that engages with the chamber and fires the round.
• Trigger group: The trigger group is responsible for releasing the trigger and allowing the gun to fire.
• Magazine: The magazine is where the gun stores the ammunition.

1. Trigger Pull: The user pulls the trigger, which releases the trigger group and allows the gun to fire.
2. Bolt Carrier Group Movement: The bolt carrier group moves forward, chambering a new round from the magazine.
3. Bolt Lockup: The bolt locks into place, preparing the round for firing.
4. Firing: The round is fired, and the bolt carrier group moves backward, ejecting the spent cartridge.
5. Reset: The bolt carrier group returns to its original position, and the process repeats.

Types of Fully Automatic Guns

There are several types of fully automatic guns, including:

• Submachine guns: Small, compact guns that fire pistol cartridges.
• Assault rifles: Intermediate-caliber guns that fire rifle cartridges.
• Machine guns: Heavy guns that fire rifle cartridges at a high rate of fire.

Advantages and Disadvantages of Fully Automatic Guns

Fully automatic guns have both advantages and disadvantages. Some of the advantages include:

• High Rate of Fire: Fully automatic guns can fire multiple rounds quickly, making them effective in combat situations.
• Ease of Use: Fully automatic guns can be easier to use in certain situations, as the user does not need to manually cock or reload the weapon.

However, fully automatic guns also have several disadvantages, including:

• Limited Accuracy: Fully automatic guns can be less accurate than semi-automatic guns, as the rapid firing can cause the gun to become less stable.
• High Maintenance: Fully automatic guns require more maintenance than semi-automatic guns, as the moving parts can wear out quickly.
• Legal Restrictions: Fully automatic guns are heavily regulated in many countries, and it may be difficult to obtain or own one legally.

Conclusion

Fully automatic guns are complex machines that require a thorough understanding of their mechanics and principles. While they have their advantages and disadvantages, fully automatic guns are an important part of modern warfare and law enforcement. By understanding how they work, we can better appreciate the technology and design that goes into these powerful weapons.
