Safety First, Always
Firearm Safety Checklist
Before you even consider picking up a wrench, the absolute priority must be safety. This is non-negotiable. Neglecting these steps could have dire consequences. Every single time you intend to work on your AR-15, irrespective of the task, the following safety checklist must be followed meticulously:
- Point in a Safe Direction: Always direct the muzzle of the firearm in a direction where an accidental discharge would not cause harm or damage. This might be a safe direction for you to be.
- Remove the Magazine: Eject the magazine, regardless of whether you believe it to be loaded. Verify visually that the magazine well is empty.
- Open the Action and Inspect the Chamber: Pull back the charging handle and visually inspect the chamber to confirm it is completely empty. There should be no round present. The bolt should be locked back in the open position.
- Confirm Empty: Physically and visually verify that no round is in the chamber by looking and by touching.
- Lock the Bolt: You may want to lock the bolt back to confirm that it is safe.
- Keep Your Finger Off the Trigger: The golden rule: unless you are intentionally aiming at a target and ready to fire, keep your finger off the trigger and outside of the trigger guard.
These steps are not optional. They are the bare minimum required to begin any disassembly procedure on your AR-15. Now that safety has been established, lets talk about the workspace.
Preparing Your Workspace
A well-organized workspace is critical to a successful and safe operation. Before gathering your tools, ensure you’re in a well-lit area. Make sure the work surface, whether a table or bench, is clear of any clutter. Clear away unnecessary items to prevent accidents and keep you focused on the task at hand.
Tools of the Trade: What You’ll Need
Having the right tools at your disposal significantly simplifies the process of removing your AR-15 stock and minimizes the risk of damage to your firearm. The following tools are essential:
- Armorers Wrench/Stock Wrench: This specialized wrench is specifically designed for loosening and tightening the castle nut that secures the buffer tube. You’ll often find these wrenches include various other cutouts and features to assist with other AR-15 maintenance tasks.
- Punch Set: You’ll need a good quality punch set to remove the roll pin that secures the stock to the buffer tube. This set typically consists of various sizes of punches, allowing you to select the one that best fits the pin. Roll pins are hollow and are designed to be tapped through.
- Hammer: A small hammer is necessary for gently tapping the punch to drive out the roll pin. Avoid using excessive force, as this could damage the receiver or the pin.
- Vice (Optional, but Recommended): A vice, if available, can provide a stable platform for holding the lower receiver while you work on it. Use vice blocks or padding to protect the receiver from scratches or dents.
- Rags or Cloths: You will need these to keep your work area clean and to wipe up oil and debris.
- Optional: Torque Wrench: If you plan to reassemble the firearm, a torque wrench is highly recommended for properly tightening the castle nut.
With your tools and materials at hand, you are now ready to start removing your stock.
Additional Materials
You may want the following available while working on your AR-15.
- Vice Blocks or Padding: Provide extra protection from accidental damage.
- Cleaning Solvent/Oil: Helpful for cleaning parts as you disassemble them.
Taking Apart the Lower Receiver: The Disassembly Process
Now that your area is secure and tools are available, let’s go through the steps to removing your AR-15 stock. Remember to be patient, work carefully, and always prioritize safety. This process is straightforward when you are patient and go step-by-step.
Preparing for Disassembly
- Confirm Safety (Again!): We cannot overemphasize safety. Reiterate the safety steps listed above. Make sure that you have physically verified that the firearm is unloaded and safe.
- Remove the Magazine: If you have not done so already, remove the magazine.
Removing the Buffer Tube
The buffer tube typically serves as the mounting point for most AR-15 stocks. Therefore, you’ll need to remove the buffer tube to access the stock.
- Loosening the Castle Nut: Locate the castle nut. It’s the large nut that secures the buffer tube to the lower receiver. Using your armorer’s wrench or stock wrench, carefully place the wrench on the castle nut. Rotate the wrench counter-clockwise to loosen the nut.
- Unscrewing the Castle Nut: Once the castle nut is loose, continue to unscrew it by hand until it comes completely free. Keep track of the end plate and spring to keep these components together.
- Removing the End Plate: Remove the end plate, which sits between the castle nut and the lower receiver.
- Unscrewing the Buffer Tube: Some buffer tubes are threaded. Once the castle nut and end plate are removed, unscrew the buffer tube from the lower receiver. Rotate the tube counter-clockwise. If it is a threaded tube, it will unscrew easily.
- Removing the Buffer and Spring (Safety Consideration): Be mindful of the buffer and buffer spring. These components are typically housed inside the buffer tube, but might be exposed once you remove the tube. The buffer spring is under tension, so slowly and carefully withdraw the buffer tube to prevent these components from springing out unexpectedly.
Removing the Stock (Dependent on the Type of Stock)
- For Adjustable Stocks: If you have an adjustable stock that slides on the buffer tube, you can simply remove it after the buffer tube has been detached from the lower receiver. Simply slide the stock off of the buffer tube.
- For Fixed Stocks (e.g., A2-style): The process to remove a fixed stock varies depending on the specific design. However, you typically need to remove the buffer tube assembly to access the mounting hardware for the stock. Some fixed stocks are held in place by a roll pin, which must be driven out with a punch and hammer. Once the pin is removed, you may be able to detach the stock.
Cleaning and Inspection
As you disassemble your AR-15, this is a good opportunity to clean the components and inspect them for wear or damage.
- Cleaning: Use a suitable cleaning solvent and a rag to remove any dirt, debris, or carbon buildup from the components, particularly the buffer tube and the lower receiver.
- Inspection: Carefully examine all parts for any signs of damage, such as cracks, dents, or excessive wear. Pay close attention to the threads of the buffer tube and the lower receiver.
Reassembly: Putting it All Back Together (Briefly)
While the focus of this guide is on removal, reassembly is equally important. Reversing the steps outlined above, carefully reassemble the components.
- Threading the Buffer Tube: If you have a threaded buffer tube, screw it back into the lower receiver.
- Installing the Buffer and Spring: Re-insert the buffer and buffer spring into the buffer tube.
- Replacing the End Plate: Slide the end plate back onto the buffer tube, aligning it with the slots in the lower receiver.
- Tightening the Castle Nut: Install the castle nut and tighten it using your armorer’s wrench or stock wrench. If you have a torque wrench, refer to your rifle’s specifications for the recommended torque setting.
Troubleshooting: Handling Common Issues
Even with the best preparation, you might encounter a few challenges during the process. Here are some common problems and their solutions:
- Castle Nut is Stuck: If the castle nut is difficult to loosen, try the following:
- Ensure the wrench is properly seated on the nut.
- Apply penetrating oil to the threads and let it soak for a few minutes.
- Use a larger wrench or a breaker bar for added leverage.
- If necessary, secure the lower receiver in a vice (with protective blocks) to provide stability.
- Roll Pin is Difficult to Remove: If the roll pin is stubborn, try the following:
- Ensure you’re using a correctly sized punch.
- Apply penetrating oil to the pin.
- Use a hammer of appropriate weight and strike the punch firmly.
- Thread Damage: Be extremely careful not to cross-thread any components. If you detect damage to the threads, cease the procedure and seek assistance from a qualified gunsmith.
Conclusion: Mastering the AR-15 Stock Removal
