The PSA (Palmetto State Armory) M110 is a popular AR-10 platform rifle, known for its affordability and decent performance. Many owners customize their rifles, and stock replacement is a common modification. This guide will walk you through the process of removing the PSA M110 stock safely and efficiently.
Tools Required
Before you begin, ensure you have the following tools:
- A punch (brass is recommended to avoid damaging the receiver): This will be used to push out the retaining pin.
- A hammer: Use a mallet or rubber hammer to prevent marring the metal.
- A small container or rag: This is for catching the retaining pin to prevent loss.
Step-by-Step Removal Process
Safety First: Always ensure the firearm is unloaded and cleared before attempting any disassembly. Point the rifle in a safe direction and double-check that the chamber is empty.
-
Locate the Retaining Pin: The stock is typically held in place by a single retaining pin located at the rear of the receiver, where the buffer tube meets the receiver extension. This pin might be slightly recessed, so carefully examine the area.
-
Punch Out the Retaining Pin: Using your punch and hammer, gently tap the retaining pin out from the receiver extension. Start with light taps and gradually increase force if needed. Work the punch from either side, alternating if necessary to ensure even pressure. Catch the pin as it exits the receiver to prevent it from getting lost.
-
Remove the Stock: Once the retaining pin is removed, the stock should slide off the buffer tube. If it's stuck, gently wiggle and pull it straight rearward. Avoid excessive force, as this could damage components.
-
Inspect the Components: Once the stock is removed, visually inspect the buffer tube, receiver extension and the stock itself for any damage or wear.
Troubleshooting Common Issues
-
Stuck Retaining Pin: If the retaining pin is stubborn, try using a lubricant like gun oil to help it move more freely. Apply a small amount to the pin and allow it to sit for a few minutes before trying again. Never use excessive force, which could damage the receiver.
-
Damaged Retaining Pin: If the retaining pin is bent or damaged, you’ll need a replacement. Contact PSA or a reputable gun parts supplier.
-
Stock Won't Slide Off: Make sure the retaining pin is completely removed. If the stock still won't slide off, there might be some debris or build-up preventing it. Clean the area thoroughly with a suitable cleaning solvent.
Reinstalling the Stock
Reinstalling the stock is the reverse of the removal process. Ensure the buffer tube is aligned correctly before inserting the retaining pin. Tap the pin back into place using the punch and hammer, ensuring it seats firmly.
This guide should help you safely and effectively remove the stock from your PSA M110. Remember to always prioritize safety and consult a qualified gunsmith if you encounter any difficulties. Always follow safe gun handling practices.
