Disassembling an AR-15 rifle can seem daunting at first, but with a little patience and the right instructions, it's a straightforward process. This guide provides a step-by-step walkthrough, covering both field stripping (for basic cleaning) and complete disassembly (for more thorough cleaning or maintenance). Always ensure your firearm is unloaded and pointed in a safe direction before beginning any disassembly.
Safety First: Essential Precautions
Before you even think about touching your AR-15, prioritize safety:
- Unloaded Weapon: Absolutely confirm your firearm is unloaded. Visually inspect the chamber and magazine well.
- Safe Direction: Point the muzzle in a safe direction, preferably downrange at a target backstop, and away from people and obstacles.
- Clear Area: Ensure your workspace is clean and free of obstructions. Have a soft cloth or mat to prevent scratching your firearm.
- Proper Tools: Gather the necessary tools (discussed later).
Field Stripping Your AR-15 (Basic Cleaning)
This process involves removing the upper receiver from the lower receiver, allowing access to the bolt carrier group for cleaning.
Step 1: Remove the Magazine: Eject the magazine from the magazine well.
Step 2: Check the Chamber: Visually and physically check the chamber to ensure it’s empty.
Step 3: Charging Handle: Pull the charging handle to the rear to lock the bolt to the rear. This ensures the bolt carrier group is accessible.
Step 4: Upper Receiver Removal:
- Depress the takedown pins: Locate the takedown pins on either side of the lower receiver, just above the pistol grip. Use a punch or your fingers (if your AR-15 allows) to push them out. Be careful not to lose the pins!
- Separate the receivers: Carefully separate the upper and lower receivers. The upper receiver, with the bolt carrier group, will now be detached.
Step 5: Bolt Carrier Group Removal:
- Remove the charging handle: Once the upper receiver is detached, remove the charging handle by pulling it straight back.
- Remove the bolt carrier group: Grab the bolt carrier group and gently slide it out of the upper receiver.
Step 6: Cleaning and Reassembly: Clean the bolt carrier group and upper receiver thoroughly. Reassembly is the reverse of disassembly.
Complete Disassembly of Your AR-15 (Thorough Cleaning/Maintenance)
Complete disassembly allows for a deeper clean and inspection of all parts. This is more involved and requires additional tools.
Step 1: Field Strip (as above): Follow the steps outlined in the field stripping section to remove the upper receiver and bolt carrier group.
Step 2: Bolt Carrier Group Disassembly:
- Remove the Cam Pin: Use a punch or appropriate tool to drive out the cam pin located at the rear of the bolt carrier group.
- Separate the Bolt and Carrier: Once the cam pin is removed, separate the bolt and bolt carrier. Be mindful of the firing pin, which may be ejected.
Step 3: Cleaning and Inspection: Thoroughly clean each component, inspecting for wear and tear. Pay close attention to the extractor, ejector, and firing pin.
Step 4: Reassembly: Reassembly is the reverse of disassembly. Ensure all parts are correctly aligned and seated before re-installing the cam pin.
Tools You May Need:
- Punch: A small punch is useful for removing takedown pins and the cam pin.
- Cleaning Kit: A quality AR-15 cleaning kit with appropriate brushes, patches, and solvent.
- Torque Wrench (Optional): For precise tightening of screws, especially during reassembly.
- Soft Cloth or Mat: To protect your firearm during disassembly and cleaning.
