The AR-15 platform, known for its modularity and relative ease of maintenance, benefits from regular cleaning and inspection. Field stripping, a crucial part of this process, allows for thorough cleaning and lubrication, ensuring optimal performance and longevity of your firearm. This guide provides a step-by-step walkthrough of field stripping an AR-15, catering to both novice and experienced users. Safety is paramount, so always ensure your firearm is unloaded and pointed in a safe direction before beginning any maintenance.
Tools Required for AR-15 Field Stripping
Before you start, gather the following tools:
- AR-15 cleaning kit: This typically includes a cleaning rod, patches, bore brush, and gun oil.
- Punched or similar tool: Useful for removing the take-down pins.
- Soft cloth or rag: For wiping down parts and removing debris.
Step-by-Step Field Stripping of an AR-15
This guide details the process of field stripping an AR-15, separating it into its major components. Remember, always double-check the firearm is unloaded.
Step 1: Verify the Firearm is Unloaded
This cannot be stressed enough. Visually inspect the chamber and magazine well to confirm the firearm is completely unloaded. Point the firearm in a safe direction.
Step 2: Removing the Upper Receiver
- Locate the takedown pins: These are located on either side of the lower receiver, just forward of the trigger guard.
- Depress the takedown pins: Use a punch or your fingers (if possible) to depress the pins from the receiver. They will usually slide out slightly, allowing you to remove them completely.
- Separate the upper and lower receivers: Gently separate the upper receiver from the lower receiver. The upper receiver will come forward and off the lower.
Step 3: Removing the Bolt Carrier Group (BCG)
- Pull the charging handle: Pull the charging handle to the rear, locking it in place.
- Remove the bolt carrier group (BCG): With the charging handle locked to the rear, the BCG should slide out of the upper receiver. Gently guide it out.
Step 4: Disassembling the Bolt Carrier Group (Optional)
While not strictly necessary for field stripping, further disassembling the BCG allows for more thorough cleaning. This usually involves removing the bolt from the carrier and potentially disassembling the bolt itself (if necessary). Consult your firearm's manual for specific instructions on disassembling the BCG.
Reassembly of the AR-15
Reassembly is essentially the reverse of the disassembly process. Ensure each part is correctly seated and aligned before proceeding.
Step 1: Reassemble the Bolt Carrier Group (if disassembled)
Refer to your firearm’s manual for precise instructions.
Step 2: Install the Bolt Carrier Group
Insert the BCG into the upper receiver until it seats fully. Release the charging handle.
Step 3: Reattach the Upper Receiver
Align the upper and lower receivers and insert the takedown pins, ensuring they are fully seated.
Cleaning and Lubrication
Once disassembled, clean each component using your cleaning kit, paying close attention to the bolt carrier group, barrel, and chamber. After cleaning, lubricate all moving parts with gun oil, focusing on the critical contact points. Avoid over-lubrication.
Conclusion
Regular field stripping and cleaning of your AR-15 is crucial for maintaining its reliability and accuracy. This guide provides a foundation for safe and effective maintenance. However, always consult your firearm's manual for specific instructions and safety guidelines. If you're unsure about any step, seek guidance from a qualified gunsmith. Remember, safety always comes first.
