Understanding the AR Pistol Lower Receiver

The lower receiver is the foundation of your AR pistol. It houses the trigger mechanism and is considered the firearm's legal part. In the AR-15 platform, you’ll usually have two main types of lower receivers: stripped and complete.

• Stripped Lower Receiver: This is just the shell and doesn’t include the internal parts, giving you the flexibility to choose your components.
• Complete Lower Receiver: This comes fully assembled, making it easier for those who are new to building firearms.

Important Components to Consider

When building your AR pistol lower receiver, you need to have the following components:

• Lower Receiver: The actual part that is regulated by law.
• Trigger Group: Includes the trigger, hammer, and disconnector.
• Safety Selector: The switch that enables safe or fire mode.
• Pistol Grip: The part where you hold the firearm.
• Buffer Tube Assembly: Essential for the functioning of the weapon.
• Stock (if applicable): In the case of pistols, this may include a stabilizing brace.

Common Mistakes to Avoid

• Over-tightening Screws: This can lead to stripping threads and can cause parts to malfunction. Always follow manufacturer torque specifications.
• Missing Detents: Small parts like detents can easily be lost during installation. Have a clean workspace and tools handy to avoid this.
• Not Checking Compatibility: Ensure all parts are compatible with your specific lower receiver. Mismatched parts can cause significant issues during assembly.

Troubleshooting Common Issues

If you encounter problems while building your AR pistol, here are some quick tips to troubleshoot:

• If the Trigger Doesn’t Reset: Check for any obstructions in the trigger group and ensure that the hammer spring is properly installed.
• Safety Selector Won't Move: Ensure that the safety selector is properly installed and that the detent is engaging it correctly.
• Pistol Grip Wobbles: If your grip feels loose, tighten the securing screws and make sure the grip is correctly aligned with the receiver.
