Before you begin, ensure you have the necessary tools and follow all safety precautions:

  • AR-15 disassembly tool or a punch
  • Replacement firing pin (if needed)
  • Locking pliers or needle-nose pliers
  • Compressed air or a cleaning rod
  • Eye and ear protection
  • Firearm safety

Always keep the firearm pointed in a safe direction and ensure the chamber is clear of any ammunition. Never put your finger on the trigger until you are ready to fire.

Step-by-Step Guide

Follow these steps to remove the firing pin from your AR-15:

  1. Remove the magazine and chamber flag. Ensure the chamber is clear of any rounds.

  2. Remove the bolt carrier group (BCG) from the upper receiver. This can be done by pulling the charging handle back and locking it to the rear, then pulling the BCG forward and lifting it out of the receiver.

  3. Locate the firing pin retainer pin. It is a small, flat-head pin that holds the firing pin in place. Use the punch or a small hammer to gently tap the retainer pin out of the receiver. Be careful not to damage the receiver or the pin.

  4. With the retainer pin removed, you can now pull the firing pin out of the receiver. It may be necessary to use locking pliers or needle-nose pliers to grip the firing pin and pull it out.

  5. Inspect the firing pin for any signs of wear or damage. If it is in good condition, you can skip to the reassembly steps. If it needs to be replaced, proceed to the next section.

Replacing the Firing Pin

Follow these steps to replace the firing pin:

  1. Insert the new firing pin into the receiver. Ensure it is properly seated and that the firing pin retainer pin hole is aligned with the firing pin.

  2. Insert the firing pin retainer pin back into the receiver. Use the punch to gently tap the pin into place. Be careful not to damage the receiver or the pin.

  3. Reassemble the BCG by sliding it back into the upper receiver. Ensure the charging handle is locked to the rear and the BCG is fully seated.

  4. Reinstall the magazine and chamber flag.
