Removing the stock from an AR-15 rifle can be necessary for maintenance, customization, or replacement. Whether you’re upgrading your firearm or simply inspecting internal components, knowing how to properly remove the stock ensures safety and preserves the integrity of your rifle. This guide will walk you through the process clearly and safely.
What You’ll Need
- AR-15 rifle with the stock to be removed
- Flathead screwdriver or punch tool (optional, depending on stock type)
- Cleaning cloth or mat to work on
- Safety glasses
- Gun oil or lubricant (optional, for maintenance after removal)
Step-by-Step
- Ensure Safety First: Before beginning, make sure the rifle is unloaded. Remove the magazine and check the chamber visually and physically to confirm no ammunition is present.
- Place the Rifle on a Clean Surface: Use a padded mat or cloth to prevent scratches and keep small parts from rolling away.
- Identify the Stock Type: Most AR-15 stocks are either fixed or adjustable (collapsible). The removal process varies slightly depending on the type.
- For Adjustable (Collapsible) Stocks:
- Locate the adjustment lever or button, usually on the underside of the stock.
- Push or pull the lever to slide the stock to its rearmost position.
- With the stock fully extended or collapsed, locate the buffer tube castle nut and end plate (visible at the junction of the stock and receiver extension).
- Using your hands or a punch tool if necessary, depress the detent pin inside the buffer tube that holds the stock in place.
- While holding the detent pin, slide the stock off the buffer tube carefully.
- For Fixed Stocks:
- Look for screws or bolts securing the stock to the lower receiver or buffer tube.
- Use a flathead screwdriver or appropriate tool to unscrew these fasteners.
- Once screws are removed, gently pull the stock away from the receiver.
- Remove Buffer and Spring (If Necessary): On some models, the buffer tube contains a buffer and spring that may need to be removed to fully detach the stock.
- Depress the buffer retainer pin inside the buffer tube.
- Carefully pull the buffer and spring out.
- Inspect the Stock and Buffer Tube: Check for dirt, damage, or wear. This is a good time to clean or lubricate parts if desired.
- Store Parts Safely: Keep screws, pins, and small components in a container to prevent loss.
- Reassemble or Replace: If installing a new stock, reverse the steps according to the new stock’s instructions.
Common Mistakes
- Skipping Safety Checks: Failing to unload and clear the firearm before starting can lead to dangerous situations.
- Forcing the Stock: Applying excessive force when removing the stock or buffer can damage pins or the buffer tube.
- Ignoring Detent Pins: Not properly depressing or accounting for detent pins can cause parts to become stuck or break.
- Misplacing Small Parts: Losing screws, pins, or springs often leads to improper reassembly or malfunction.
- Using Incorrect Tools: Using the wrong screwdriver or punch can strip screws or damage components.
Tips
- Wear safety glasses to protect your eyes from springs or pins that might pop loose unexpectedly.
- Work in a well-lit area with a clean surface to easily spot small parts.
- If you encounter resistance, double-check for hidden screws or pins before applying more force.
- Keep a small container or magnetic tray nearby to hold screws and pins during disassembly.
- After removal, clean the buffer tube and inside the stock to remove debris and ensure smooth operation.
- Consult your specific stock manufacturer’s instructions if available, as designs can vary.
Troubleshooting
Stock Won’t Slide Off the Buffer Tube: Ensure the adjustment lever or button is fully engaged to unlock the stock. Check if the detent pin is depressed; if stuck, gently wiggle or use a small punch to free it. Avoid forcing to prevent damage.
Buffer or Spring is Stuck: Depress the buffer retainer pin fully and pull the buffer straight out. If it resists, apply a small amount of lubricant and gently work it free.
Screws Won’t Unscrew: Use the correct screwdriver size and apply steady pressure. If the screw is stripped, a screw extractor or professional gunsmith may be required.
Lost Small Parts: Check your workspace thoroughly. If parts are missing, replacements can be ordered from firearm parts suppliers or the manufacturer.
Stock Feels Loose After Reassembly: Verify all screws and pins are securely fastened. For adjustable stocks, ensure the locking mechanism fully engages the buffer tube.
