The AR-15 lower receiver is the part of the rifle that houses the trigger mechanism, magazine well, and the buffer tube, among other critical components. It's the only part of the AR-15 that is legally classified as a firearm in most jurisdictions, which means it must be serialized and transferred through an FFL dealer when purchased.

Helpful Tips for Selecting and Using Your Lower Receiver

When navigating the vast landscape of AR-15 lower receivers, keep these essential tips in mind:

Research Compatibility

Before purchasing a lower receiver, ensure compatibility with the upper receiver and other parts of your rifle. Most AR-15s use standard mil-spec components, but it's always good to check.

Consider Your Purpose

Are you building a rifle for home defense, competition, or just for fun? Understanding your purpose can help guide your choice. For example, lighter materials may be better for long-range shooting.

Don’t Overlook the Finish

The finish of the lower receiver affects both aesthetics and durability. Anodized finishes provide excellent protection against corrosion and wear while adding a sleek look.

Check for Manufacturer Warranty

A good warranty can save you a headache down the line. Reputable brands often provide warranties that cover defects in materials or workmanship.

Common Mistakes to Avoid

Building an AR-15 can be exhilarating, but it's easy to make mistakes. Here are some common pitfalls to avoid:

1. Ignoring the Manual: Each receiver comes with its own set of instructions. Always refer to the manufacturer's manual during assembly.

2. Over-Torquing Screws: It’s tempting to tighten everything as much as possible, but over-torquing can damage components.

3. Using Non-Compatible Parts: Double-check the specifications of the parts you plan to use to avoid compatibility issues.

4. Not Testing Functionality: After assembly, always test your firearm's functionality in a safe environment to ensure everything operates smoothly.

Troubleshooting Common Issues

After building your AR-15, you might encounter some issues. Here are a few troubleshooting tips:

• Failure to Feed: Check if the magazine is seated properly, and ensure that the magazine is compatible with your rifle.

• Failure to Eject: Make sure the gas system is functioning correctly. Sometimes, an issue with the gas tube can cause ejection failures.

• Loose Parts: If components feel loose, ensure that all screws and pins are tightened to the recommended specifications.

• Trigger Malfunctions: Inspect the trigger assembly and ensure that all parts are correctly installed and free of debris.
