How to install the AR-15 lower part:

Installing an AR-15 lower parts kit can be a rewarding project if you follow the steps carefully. Let’s dive into a detailed guide to help you through the process. Make sure you have all the necessary tools and parts before starting.

Tools and Parts Needed:

  • AR-15 Lower Parts Kit (LPK).
  • AR-15 Lower Receiver.
  • Hammer.
  • Punch set (various sizes).
  • Small brass or plastic hammer.
  • Needle-nose pliers.
  • Roll pin holders and punches (optional, but recommended).
  • Armorer’s wrench (optional but helpful).
  • Vice and lower receiver vise block (optional but helpful).
  • Masking tape (to protect the receiver).
  • Small flathead screwdriver.

Step-by-Step Guide:

  • Prepare Your Workspace:

Ensure you have a clean, well-lit workspace.

  • Install the Magazine Catch:

Insert the magazine catch into the left side of the receiver. Place the magazine catch spring over the threaded portion on the right side. Screw the magazine release button onto the threaded portion.

  • Install the Bolt Catch:

Place the bolt catch spring and plunger into the small hole on the left side of the receiver. Position the bolt catch in place. Use a punch to hold the bolt catch in place. Insert the roll pin partially using a punch or roll pin holder. Drive the roll pin in with a small hammer or mallet.

  • Install the Trigger Guard:

Use a roll pin holder to start the roll pin into the receiver. Drive the roll pin in carefully to avoid breaking the ears of the receiver.

  • Install the Trigger Assembly:

Insert the trigger spring onto the trigger. Place the disconnector spring into the trigger. Place the disconnector onto the trigger, and install both into the receiver. Insert the trigger pin through the receiver, trigger, and disconnector. Ensure the trigger moves freely and resets when pulled and released.

  • Install the Hammer Assembly:

Attach the hammer spring to the hammer. Insert the hammer into the receiver and align it with the holes. Insert the hammer pin through the receiver and hammer. Check for proper function by pulling back on the hammer and letting it fall forward.

  • Install the Safety Selector:

Insert the safety selector into the receiver. On the opposite side, insert the safety detent and spring into the hole. Attach the pistol grip, securing the spring and detent in place. Tighten the pistol grip screw.

  • Final Function Check:

Ensure all parts move freely and function correctly. Check the magazine catch, bolt catch, trigger, hammer, and safety selector.

Safety Tips:

The safety tips include:

  • Always work carefully and methodically.
  • Use appropriate tools to avoid damaging the receiver or parts.
  • Wear safety glasses to protect your eyes from flying springs or detents.
