This comprehensive guide will walk you through the essential components of an AR-15 kit, excluding the lower receiver. By the end, you’ll have a clear understanding of what to expect and how to put together a high-quality firearm.
Understanding the AR-15 Kit
An AR-15 kit typically includes all the necessary parts to build a functional rifle, except for the lower receiver. The lower receiver is the part that houses the magazine, trigger, and fire control group, and it requires a unique serial number for legal purposes. By purchasing a kit without the lower receiver, you can save money and customize your rifle to your liking.
The Key Components of an AR-15 Kit
When you purchase an AR-15 kit, you can expect to receive the following components:
| Component | Description |
|---|---|
| Upper Receiver | The upper receiver is the part that houses the barrel, handguard, and sights. It is available in various calibers, such as .223, .308, and 9mm. |
| Barrel | The barrel is the tube that the bullet travels through. It is available in different lengths and profiles, affecting the rifle’s weight, balance, and accuracy. |
| Handguard | The handguard is the part that covers the barrel and provides a place to grip the rifle. It comes in various materials, such as aluminum, polymer, and carbon fiber. |
| Sights | Sights are the tools used to aim the rifle. They can be iron sights, scopes, or red dot sights. |
| Stock | The stock is the part that fits over the receiver and provides a place to rest your shoulder. It comes in various lengths and materials, such as wood, polymer, and composite. |
| Trigger Group | The trigger group includes the trigger, hammer, and sear. It is responsible for the firing mechanism of the rifle. |
