AR-15 Action: A Comprehensive Guide for Enthusiasts
The AR-15 action is a highly sought-after firearm component, renowned for its reliability, accuracy, and versatility. Whether you’re a seasoned shooter or a beginner looking to delve into the world of firearms, understanding the AR-15 action is crucial. In this article, we will explore the various aspects of the AR-15 action, from its history to its components and maintenance.
History of the AR-15 Action
The AR-15 action was developed by Eugene Stoner in the early 1950s. Initially designed for the U.S. military, the firearm was intended to replace the M1 Garand. The AR-15 action was a revolutionary design, featuring a lightweight, gas-operated, and semi-automatic firing mechanism. Over the years, the AR-15 action has become a favorite among civilian shooters, hunters, and law enforcement agencies.
Components of the AR-15 Action
The AR-15 action is composed of several key components, each playing a crucial role in the firearm’s operation. Here’s a breakdown of these components:
| Component | Description |
|---|---|
| Receiver | The receiver is the central component of the AR-15 action, housing the bolt carrier group, trigger group, and magazine. It is typically made of aluminum or steel. |
| Bolt Carrier Group | The bolt carrier group is responsible for cycling the action, including feeding, extracting, and ejection of the rounds. It consists of the bolt, carrier, and gas key. |
| Trigger Group | The trigger group includes the trigger, hammer, and sear. It is responsible for initiating the firing sequence when the trigger is pulled. |
| Barrel | The barrel is the tube through which the bullet travels. It is typically made of stainless steel or chrome-molybdenum steel and is available in various lengths and calibers. |
| Gas System | The gas system is responsible for controlling the amount of gas that is bled from the barrel to cycle the action. It consists of the gas block, gas tube, and gas key. |
| Handguard | The handguard is the tube that covers the barrel and provides a grip for the shooter. It is available in various materials, including aluminum, polymer, and carbon fiber. |
| Stock | The stock is the part of the firearm that is held against the shoulder. It is available in various lengths and materials, including wood, synthetic, and composite. |
Types of AR-15 Actions
There are several types of AR-15 actions, each with its own unique features and benefits. Here are some of the most common types:
- Standard Action: The standard action is the most common type of AR-15 action. It features a direct impingement gas system and is known for its simplicity and reliability.
- Short Stroke Action: The short stroke action is a modified version of the standard action that reduces the amount of gas bled from the barrel, resulting in a smoother cycling action.
- Long Stroke Action: The long stroke action is another modified version of the standard action that provides better gas control and is often used in custom builds.
- Direct Impingement: The direct impingement system is the most common gas system used in AR-15 actions. It routes the gas directly into the bolt carrier group, cycling the action.
- Gas Piston: The gas piston system is a newer design that uses a separate piston to control the gas flow, resulting in reduced wear and improved reliability.
Maintenance and Care
Proper maintenance and care are essential for ensuring the longevity and performance of your AR-15 action. Here are some key tips:
- Cleanliness: Regularly clean your firearm, including the barrel, bolt carrier group, and
