Removing an AR-15 stock is a fundamental task for any AR-15 owner, whether for cleaning, maintenance, customization, or replacing a damaged or worn-out stock. This process is generally straightforward, but understanding the specific type of stock you have is crucial. This guide covers the most common methods. Always ensure your firearm is unloaded and pointed in a safe direction before beginning any disassembly.
Identifying Your AR-15 Stock Type
Before you begin, you need to identify the type of stock you have. There are primarily two types:
- Fixed Stocks: These stocks are permanently attached to the receiver extension (buffer tube). They cannot be removed without tools.
- Collapsible Stocks: These stocks can be adjusted in length and usually have a locking mechanism that allows for easy removal and reattachment.
Removing a Fixed AR-15 Stock
Removing a fixed stock requires specialized tools and a bit more care. This is less common on modern AR-15s.
Tools Required:
- Castle Nut Wrench: This wrench is specifically designed to remove the castle nut that secures the stock to the receiver extension.
- Receiver Extension Wrench (Optional but Recommended): This wrench helps to hold the receiver extension steady while you loosen the castle nut, preventing damage.
- Punch (small diameter): May be needed to help loosen stubborn castle nuts.
Steps:
- Secure the Receiver Extension: Use the receiver extension wrench to firmly grip the receiver extension. This prevents it from rotating while you loosen the castle nut.
- Loosen the Castle Nut: Using the castle nut wrench, carefully begin loosening the castle nut. It will likely be very tight. Turn counter-clockwise. A punch can assist if the nut is extremely stubborn.
- Remove the Castle Nut: Once the castle nut is loose, remove it completely from the receiver extension.
- Remove the Stock: With the castle nut removed, the stock should slide off the receiver extension. There might be a slight resistance, use gentle force if necessary. If you have difficulty removing the stock, gently tap it away from the receiver using a rubber mallet.
Important Considerations:
- Thread Lock: The castle nut often has thread locker applied. This can make removal more difficult. Using the right tools and applying moderate force is key.
- Damage Prevention: Be careful not to damage the receiver extension or the stock during this process. Use the correct tools and avoid excessive force.
Removing a Collapsible AR-15 Stock
Removing a collapsible stock is significantly easier.
Tools Required:
- Usually no tools are required.
Steps:
- Locate the Stock's Release Button or Lever: Most collapsible stocks have a button or lever typically located near the receiver extension.
- Depress or Rotate the Release Mechanism: Press the button or rotate the lever according to the stock's design. Consult your stock's manual if unsure.
- Slide the Stock Off: Once the release mechanism is engaged, the stock should slide off easily.
Reinstalling the AR-15 Stock
Reinstalling the stock follows the reverse steps of removal. Remember to properly tighten the castle nut (if applicable) to ensure the stock is securely attached. Over-tightening can damage the threads.
Safety Precautions
- Always handle firearms responsibly. Keep the firearm unloaded and pointed in a safe direction at all times.
- Use the correct tools. Using improper tools can lead to damage to your firearm.
- If you are unsure about any step, consult a qualified gunsmith.
This guide provides a general overview. Specific procedures might vary depending on the manufacturer and model of your AR-15 stock. Always refer to your firearm's manual and the manufacturer's instructions for detailed guidance.
