AR-15 Builds: A Comprehensive Guide for Aspiring Gun Enthusiasts

Are you looking to build your own AR-15 rifle? Whether you’re a seasoned shooter or a beginner, the process of building an AR-15 can be both exciting and rewarding. In this article, we’ll delve into the various aspects of AR-15 builds, from choosing the right components to assembling and maintaining your firearm. Let’s get started!

Understanding the Basics

The AR-15 is a popular semi-automatic rifle that has gained a reputation for its accuracy, reliability, and customizable nature. Before diving into the build process, it’s essential to understand the basic components of an AR-15 rifle.

Component Description
Receiver The receiver is the central part of the rifle that houses the trigger group, bolt carrier group, and magazine.
Bolt Carrier Group (BCG) The BCG is responsible for cycling the action of the rifle, including feeding, extracting, and ejection of rounds.
Barrel The barrel is the tube through which the bullet travels and is the primary determinant of accuracy and velocity.
Stock The stock is the part of the rifle that provides support and allows the shooter to control the firearm.
Handguard The handguard is the tube that covers the barrel and provides a place for the shooter to grip the rifle.
Trigger Group The trigger group includes the trigger, hammer, and sear, which are responsible for the firing mechanism.

Now that we have a basic understanding of the components, let’s explore the process of selecting the right parts for your AR-15 build.

Selecting the Right Parts

Choosing the right parts for your AR-15 build is crucial to ensure the rifle’s performance and reliability. Here are some key factors to consider when selecting components:

Receiver

The receiver is the heart of your AR-15 rifle. There are two types of receivers: mil-spec and commercial. Mil-spec receivers are made from aluminum and are known for their durability and strength. Commercial receivers are typically made from 7075 aluminum and are lighter. Consider your budget and intended use when selecting a receiver.

Bolt Carrier Group (BCG)

The BCG is another critical component that determines the rifle’s performance. There are several options to choose from, including full-auto, mil-spec, and commercial BCGs. Full-auto BCGs are designed for use with full-auto firearms, while mil-spec and commercial BCGs are suitable for semi-automatic rifles. Ensure that the BCG you choose is compatible with your rifle’s caliber and chamber.

Barrel

The barrel is the most significant factor in determining the rifle’s accuracy and velocity. When selecting a barrel, consider the following factors:

  • Caliber: Choose a caliber that suits your intended use, such as .223 Remington, 5.56 NATO, or .308 Winchester.

  • Length: Barrels come in various lengths, such as 16″, 18″, and 20″. Longer barrels typically offer better accuracy and velocity, but they may be heavier and more challenging to maneuver.

  • Profile: The barrel profile affects the rifle’s weight and balance. A heavier profile can improve accuracy but may make the rifle more challenging to carry.

  • Twist Rate: The twist rate determines how well the barrel stabilizes the bullet. A higher twist rate is typically better for heavier bullets.

Stock

The stock is an essential component that provides support and allows the shooter to control the firearm. There are various stock options available, including collapsible, fixed, and telescoping stocks. Consider your comfort, intended use, and the weight of the rifle when selecting a stock.

Handguard

The handguard is the tube that covers the barrel and provides a place for the shooter
