How to Safely Break Down and Reassemble an AR-15
The AR-15 platform, known for its modularity, allows for easy breakdown and reassembly. This is beneficial for cleaning, maintenance, transportation, and storage. However, safety should always be the top priority during any firearm handling. This guide provides general instructions; always consult your firearm's manual for specific details and safety precautions.
Before You Begin:
- Unloaded Weapon: Absolutely confirm the firearm is unloaded. Visually inspect the chamber and magazine well. Point the muzzle in a safe direction.
- Safe Environment: Choose a clean, well-lit area with enough space to lay out parts without risk of loss or damage.
- Tools: You will likely only need your fingers for this process, though a nylon cleaning rod or similar tool might aid in removing the bolt carrier group.
Step-by-Step Breakdown:
-
Remove the Magazine: Depress the magazine release button and allow the magazine to drop free.
-
Check the Chamber (Again!): Visually and physically check the chamber again to ensure it is empty.
-
Charging Handle: Pull the charging handle to the rear to lock the bolt to the rear. This ensures the bolt is not going to move unexpectedly during the disassembly process.
-
Upper Receiver Removal: Locate the takedown pins on either side of the lower receiver. Using a punch or your fingers (depending on the design), push them out. The upper receiver should then separate from the lower receiver.
-
Bolt Carrier Group (BCG) Removal: With the upper receiver separated, you will now remove the bolt carrier group. This typically involves simply pulling it straight back. It might require a slight amount of force, but excessive force isn't needed.
-
Buffer Tube Removal (Optional): If you are doing a more thorough cleaning, you might remove the buffer tube. This involves unscrewing the castle nut from the end of the buffer tube using a wrench. (Note: This is often the most difficult step and requires specialized tools).
Reassembly:
Reassembly is the reverse of the breakdown process. Ensure all parts are correctly aligned and seated before re-installing takedown pins. Pay attention to the proper orientation of the BCG and ensure the charging handle cycles smoothly. After reassembly, always check function before shooting.
Safety Considerations:
- Always treat every firearm as if it were loaded.
- Never point the firearm at anything you are not willing to destroy.
- Keep your finger off the trigger until you are ready to shoot.
- Be aware of your surroundings.
- Use proper eye and hearing protection.
Beyond Basic Disassembly:
This guide covers the basic breakdown of an AR-15. More advanced disassembly might be needed for deep cleaning or part replacement. These processes may require specialized tools and a greater understanding of the firearm's internal mechanisms. Refer to your firearm's manual and/or seek guidance from a qualified gunsmith for these more advanced procedures.
