The PSA (Palmetto State Armory) M110 is a popular AR-10 platform rifle known for its versatility and accuracy. One common modification is changing the stock, whether for personal preference, improved ergonomics, or to accommodate specific accessories. This guide provides a detailed, step-by-step process for safely and efficiently removing the stock from your PSA M110. Always prioritize safety when handling firearms. Ensure the weapon is unloaded and the chamber is clear before beginning any disassembly.
Tools Required
Before you start, gather the necessary tools:
- A punch: A small, appropriately sized punch (brass is preferred to avoid marring the metal) will be needed to push out the retaining pin.
- A hammer: Use a hammer to gently tap the punch. Avoid excessive force.
- A magnetic parts tray: This will help prevent losing small parts during the process.
Step-by-Step Removal Process
-
Safety First: Confirm your firearm is unloaded. Visually inspect the chamber and magazine well. This is paramount.
-
Locate the Retaining Pin: The stock is typically secured by a single retaining pin located at the rear of the receiver extension (buffer tube). This pin may be slightly recessed.
-
Insert the Punch: Carefully insert the punch into the retaining pin's hole. Ensure the punch is properly aligned to avoid damaging the receiver extension.
-
Tap the Punch: Gently tap the punch with the hammer. Avoid using excessive force; the pin should move out relatively easily. If it's resistant, re-check your alignment.
-
Remove the Retaining Pin: Once the pin is loosened, it should be able to be pushed fully out with your fingers or the punch. Catch the pin to prevent it from getting lost.
-
Remove the Stock: With the retaining pin removed, the stock should slide off the receiver extension. You may need to gently wiggle or rotate the stock to free it.
Troubleshooting and Considerations
-
Stuck Retaining Pin: If the retaining pin is particularly stubborn, try applying a small amount of penetrating oil to the area. Allow it to sit for a few minutes before attempting to remove the pin again. Avoid excessive force, as this could damage the receiver extension.
-
Different Stock Types: While the basic process remains the same, the exact location and style of the retaining pin may vary slightly depending on the specific stock installed on your PSA M110. Consult your owner's manual or the manufacturer's instructions if you encounter differences.
-
Replacing the Stock: Once the old stock is removed, installing a new stock is generally the reverse of this process. Ensure the new stock is compatible with your AR-10 platform before installation.
Conclusion
Removing the stock from your PSA M110 is a straightforward process if followed carefully. By following these steps and prioritizing safety, you can successfully remove and replace your stock, customizing your rifle to your specific needs. Remember to always consult your firearm's owner's manual and to practice safe gun handling techniques. Improper handling can lead to serious injury.
