Ar Pistol Upper: A Comprehensive Guide
Are you looking to enhance your firearm collection or simply curious about the intricacies of an AR pistol upper? Look no further. This article delves into the details of an AR pistol upper, covering its components, features, and the reasons why it’s a favorite among firearm enthusiasts.
Understanding the AR Pistol Upper
The AR pistol upper is the uppermost part of an AR-15 rifle, which includes the barrel, handguard, and sights. It is the part that is often replaced or customized to suit the user’s needs. Unlike the lower receiver, which is the part that houses the magazine and trigger, the upper receiver is where the action of the firearm takes place.
Components of an AR Pistol Upper
Let’s take a closer look at the key components of an AR pistol upper:
| Component | Description |
|---|---|
| Barrel | The barrel is the tube through which the bullet travels. It is available in various lengths and calibers, affecting the rifle’s accuracy, weight, and overall performance. |
| Handguard | The handguard is the tube that runs along the barrel, providing a place for the shooter’s hand to grip the firearm. It also protects the barrel from heat and damage. |
| Sights | Sights are used to aim the firearm. They can be iron sights, which are fixed to the firearm, or optics, which are mounted on top of the handguard. |
| Gas Block | The gas block is a component that controls the amount of gas that is released from the barrel to cycle the action of the firearm. |
| Gas Tube | The gas tube is a hollow tube that carries the gas from the barrel to the action of the firearm. |
