Custom AR-15 Complete Lower Receivers: A Comprehensive Guide
When it comes to building your own AR-15 rifle, one of the most crucial components you’ll need is the lower receiver. This part not only serves as the foundation for your firearm but also determines the legal classification of your rifle. In this article, we’ll delve into the world of custom AR-15 complete lower receivers, exploring their features, benefits, and how to choose the right one for your needs.
Understanding the Lower Receiver
The lower receiver is the part of the AR-15 that houses the magazine, trigger, and fire control group. It’s the only part of the rifle that requires a serial number and is subject to strict regulations in many countries. There are two types of lower receivers: standard and pistol grip.
| Type | Description |
|---|---|
| Standard | Standard lower receivers are designed for use with a stock and are typically used in rifles. They are subject to stricter regulations and require a serial number. |
| Pistol Grip | Pistol grip lower receivers are designed for use with a pistol grip and are often used in carbines. They are subject to less stringent regulations and may not require a serial number. |
When choosing a lower receiver, it’s important to consider the intended use of your rifle. If you plan to use it for hunting or competitive shooting, a standard lower receiver may be the better choice. If you’re looking for a more compact, concealed-carry rifle, a pistol grip lower receiver might be more suitable.
Features to Consider
When shopping for a custom AR-15 complete lower receiver, there are several features to consider to ensure you get the best possible product for your needs.
- Material: Most lower receivers are made from either aluminum or polymer. Aluminum receivers are known for their durability and strength, while polymer receivers are lighter and more resistant to corrosion.
- Finish: The finish of your lower receiver can affect its appearance and durability. Common finishes include anodizing, hardcoat anodizing, and Parkerizing.
- Fit and Finish: A well-fitted lower receiver will ensure a tight, secure fit with your firearm. Pay attention to the fit of the magazine well, trigger group, and other components.
- Customization Options: Some lower receivers offer customization options, such as different colors, grip textures, and magazine well designs.
When selecting a lower receiver, it’s important to balance your desired features with your budget. High-end receivers may offer superior quality and features, but they can also be more expensive.
