Knowing how to take apart your AR-15 is crucial for cleaning, maintenance, and troubleshooting. This comprehensive guide will walk you through the process, covering safety precautions and offering detailed instructions for both field stripping and complete disassembly. We'll cover various AR-15 models and address common questions. Mastering this skill will enhance your understanding and confidence in handling your firearm.
Safety First: AR-15 Disassembly Precautions
Before beginning any disassembly, always follow these safety rules:
- Ensure the firearm is unloaded. Visually and physically inspect the weapon to confirm there is no ammunition in the chamber or magazine.
- Point the muzzle in a safe direction. This means away from yourself, others, and any obstacles. Consider a dedicated gun cleaning area.
- Wear safety glasses. Small parts can spring out unexpectedly. Protecting your eyes is vital.
- Work on a clean, well-lit surface. This will help you avoid losing small parts or scratching your rifle.
- Consult your owner's manual. Specific instructions may vary slightly depending on the manufacturer and model of your AR-15.
Field Stripping Your AR-15: A Step-by-Step Guide
Field stripping involves removing the upper receiver from the lower receiver. This is generally sufficient for routine cleaning.
-
Check for Ammunition: Double-check the chamber and magazine are empty.
-
Remove the Magazine: Press the magazine release button and remove the magazine.
-
Charging Handle: Pull the charging handle to the rear and hold it back. This will lock the bolt carrier group (BCG) to the rear.
-
Upper Receiver Removal: Push the takedown pins out (these are usually located on either side of the lower receiver, just below the upper receiver). Use a punch or a takedown pin tool to prevent damaging the pins. Gently rotate the upper receiver forward and off the lower receiver.
-
Bolt Carrier Group Removal (Optional): Once the upper receiver is removed, the bolt carrier group (BCG) can be removed. This is often necessary for deep cleaning. Simply pull the BCG straight back.
-
Cleaning: Thoroughly clean the components using a suitable cleaning kit and lubricant.
Complete Disassembly of the AR-15: A Deeper Dive
Complete disassembly goes beyond field stripping, allowing for more thorough cleaning and maintenance. This process involves breaking down the upper and lower receivers into their individual parts.
Upper Receiver Disassembly:
-
Bolt Carrier Group Removal (if not already removed): Pull the BCG straight back and out of the upper receiver.
-
Gas Key Removal (Advanced): The gas key is a crucial component, and its removal requires specialized tools and expertise. This should be done only if absolutely necessary, as improper handling can damage the BCG.
-
Bolt Disassembly (Advanced): Similar to the gas key, bolt disassembly requires careful attention to detail and specialized tools. This is usually only performed by experienced gunsmiths.
Lower Receiver Disassembly:
-
Firing Pin Retainer Removal: Carefully remove the firing pin retainer. This requires specialized tools and delicate handling.
-
Firing Pin Removal: Remove the firing pin.
-
Hammer and Trigger Group Removal: This usually involves removing the hammer and trigger pins and gently extracting the components.
-
Buffer Tube Removal: Remove the rear takedown pin to separate the lower receiver from the buffer tube.
Reassembly: Reverse the steps outlined above for reassembly. Ensure all parts are correctly seated and aligned before re-installing the upper receiver.
Troubleshooting Common Issues During AR-15 Disassembly
- Stuck Takedown Pins: Lightly tap them from the other side with a punch or mallet. Using excessive force is not recommended.
- Difficult Bolt Carrier Group Removal: Ensure the charging handle is fully locked to the rear. If it's still stuck, check for obstructions or debris.
- Lost Parts: Work in a well-lit area with a suitable surface to prevent small parts from getting lost.
Conclusion: Mastering Your AR-15
Regularly taking apart and cleaning your AR-15 is essential for maintaining its reliability and accuracy. This guide has provided a comprehensive overview of the process, emphasizing safety and detailing both field stripping and complete disassembly. Remember, if you are uncomfortable performing any of these steps, seek the assistance of a qualified gunsmith. Proper maintenance will ensure your AR-15 functions flawlessly for years to come. Always adhere to safe gun handling practices and consult your owner's manual for any specific instructions pertaining to your particular model.
