So, let’s embark on this exciting journey together!
Design and Construction
The AR pump action is a semi-automatic firearm that has gained immense popularity among hunters, shooters, and enthusiasts worldwide. Its design is a blend of simplicity and efficiency, making it a favorite among many. Let’s take a closer look at its construction and components.
| Component | Description |
|---|---|
| Receiver | The receiver is the main housing of the firearm, which holds the action and contains the magazine. It is typically made of aluminum or steel. |

| Safety | The safety is a mechanism that prevents the firearm from firing. It can be engaged or disengaged by the shooter. |
Functionality
The AR pump action operates on the principle of a reciprocating action, where the barrel and action move back and forth to cycle the firearm. Let’s explore how it functions step by step.
-
When the trigger is pulled, the hammer or striker is released, causing the firearm to fire.
-
After the bullet is fired, the barrel and action move back due to the force of the expanding gases.
-
As the barrel and action move back, the spent cartridge case is ejected from the firearm.
-
The charging handle is pulled back, which moves the bolt carrier group forward, picking up a new cartridge from the magazine.
-
The bolt carrier group moves back, chambering the new cartridge and locking it into place.
-
The barrel and action move forward, chambering the new cartridge and preparing the firearm for the next shot.
History and Evolution
The AR pump action has a rich history that dates back to the early 20th century. Let’s take a look at its evolution and the key milestones in its development.
Early Years
The AR pump action was first introduced in the 1930s by John Garand, an American inventor. His design was based on the concept of a reciprocating action, which was inspired by the German Mauser K98 rifle. The first iteration of the AR pump action was the M1 Garand, which was adopted by the United States military during World War II.
Post-War Developments
After World War II, the M1 Garand was replaced by the M14 rifle, which was a further evolution of the AR pump action. The M14 was used by the United States military for several decades and was also adopted by various other countries around the world.
Modern Era
In the 1970s, the AR pump action experienced a resurgence in popularity with the introduction of the Ruger
