Prioritizing Safety: The Cornerstone of Any Gun Handling Procedure
The Golden Rule: Unloading the Firearm
The first and most critical step is to ensure the firearm is unloaded. This is the single most important safety measure. Treat every gun as if it is loaded. Open the action and visually and physically inspect the chamber and magazine to confirm they are empty. Look for any rounds that may be present. If you find a round, remove it and store it safely away from the work area. After unloading, it’s always good practice to work the action a few times to make absolutely certain any remaining rounds are ejected.
Direction is Key: Maintaining a Safe Muzzle Orientation
Always point the muzzle of the Remington 870 in a safe direction, ideally in a direction where an accidental discharge would not cause harm or damage. This might be towards a safe backstop, a direction away from people and property, or an area where a potential discharge is contained. Continually monitor and maintain this safe direction throughout the entire process.
Eye Protection: Shielding Your Sight
Wear appropriate eye protection. This is crucial to prevent injury from small parts, springs, or debris that could dislodge during the forearm removal process. Safety glasses provide a simple yet effective barrier against potential hazards.
Workspace Matters: Creating a Safe and Organized Environment
Choose a well-lit and uncluttered workspace. A clean, organized area minimizes the risk of misplacing small parts or having tools roll away. A workbench is ideal but any stable surface can be used, just ensure there is enough space to move freely and work comfortably. A clear workspace also makes it easier to see what you are doing.
Tools and Materials: Gathering What You Need
Successful forearm removal requires the correct tools and materials. Having everything on hand before you start streamlines the process and reduces the chance of rushing and making mistakes. Here’s a list of the essential items:
Screwdriver:
You will likely need a flathead screwdriver, but be prepared for a potential variation depending on the specific model. Make sure your screwdriver fits the action bar nut/screw snugly to avoid damaging the screw head. Consider having a few different sizes on hand just in case.
Bench Vise (Recommended):
A bench vise provides stability and allows you to use both hands for the removal. While not strictly necessary, it can significantly improve the ease and safety of the process.
Soft Jaws (Optional):
If you’re using a vise, soft jaws are recommended. These are made of plastic or rubber and protect the finish of your shotgun from scratches or damage.
Cleaning Supplies (If cleaning):
If you plan on cleaning the action during this process, gather the appropriate cleaning solvent, gun oil or lubricant, and cleaning patches or brushes.
Replacement Parts (If replacing the forearm):
If you are replacing the forearm, have the new part readily available.
Gun Lubricant/Oil:
After reassembly, apply a small amount of lubricant to ensure smooth operation.
Taking Apart the System: A Step-by-Step Approach
Now that you have the right tools and materials and have firmly established your commitment to safety, you’re ready to begin the Remington 870 forearm removal. Follow these steps carefully:
Verifying Safety (Again): The Double Check
Reiterate the safety steps. Ensure that the chamber and magazine are empty. Make sure the muzzle is pointed in a safe direction. Consider making a visual confirmation with your own eyes. Never assume a gun is unloaded.
Securing the Shotgun: Enhancing Stability
While optional, securing the shotgun in a vise significantly improves stability. Place the shotgun in the vise, clamping on the receiver, not the barrel. Make sure the vise grips are snug enough to hold the gun securely but not so tight that they crush or damage the receiver. If you have them, using soft jaws will protect the finish of your firearm.
Unscrewing the Fastener: Releasing the Forearm
Locate the action bar nut/screw. This is the fastener that secures the forearm to the action bars. It is typically found at the front of the forearm. Using the appropriate screwdriver, carefully loosen and remove the action bar nut/screw. Work slowly and deliberately. If the screw is stubborn, try the following techniques:
Penetrating Oil:
Apply a small amount of penetrating oil to the threads and let it sit for a few minutes to help loosen any rust or debris.
Gentle Heat:
In some cases, applying a small amount of heat with a hair dryer or heat gun (used with extreme caution) can help loosen a stuck screw. Be careful not to overheat the firearm or damage any of the components.
Proper Fit:
Ensure the screwdriver fits the screw head snugly. A poorly fitting screwdriver can strip the head and make removal impossible. Try a different screwdriver, or use the right tool for the job.
Removing the Forearm: Separating the Pieces
Once the action bar nut/screw is removed, you can pull the forearm forward and off the magazine tube. Gently slide the action bars forward through the forearm. The action bars will detach. This part should come off easily.
Cleaning and Inspecting: Maintaining Pristine Performance (Optional)
Now is a good time to clean and inspect the internal parts of your Remington 870. While the forearm is removed, examine the action bars, the magazine tube, and the inside of the receiver for wear, damage, or excessive dirt and grime.
Cleaning:
Use a suitable cleaning solvent to remove any carbon buildup, powder residue, or other contaminants. Apply the solvent to a cleaning patch and wipe down the affected areas. Use brushes or specialized tools to reach into tight spaces.
Lubrication:
After cleaning, apply a thin coat of gun oil or lubricant to the action bars, magazine tube, and other moving parts. This will help to ensure smooth operation.
Putting It All Back Together: Assembly and Function Test
Assuming you are not replacing the forearm, you are ready to reassemble the components. If you are replacing the forearm, do the following:
Assembling: Reconnecting the Forearm
Slide the action bars back into the new forearm. Ensure the action bars are correctly seated within the forearm. Position the new forearm over the magazine tube.
Securing the Forearm: Tightening and Ensuring a Secure Fit
Reinstall the action bar nut/screw and tighten it. Tighten it firmly, but do not overtighten it, as this could damage the threads.
Function Test: Checking for Smooth Operation
Cycle the action several times to ensure that the action cycles smoothly and locks up correctly. Make sure there are no signs of binding or excessive friction.
External Confirmation: Test Firing at a Safe Location
Before returning the Remington 870 to regular use, it’s important to perform a function test. This confirms the repair was correctly done.
Troubleshooting: Addressing Potential Issues
Even with careful execution, problems can arise during forearm removal and reassembly. Here’s how to handle some common issues:
Forearm Stuck:
If the forearm is difficult to remove after the action bar nut/screw is removed, check for any obstructions, such as rust or debris. Use a rubber mallet to gently tap the forearm forward, but never force it.
Stubborn Action Bar Nut/Screw:
If the nut/screw won’t budge, try penetrating oil, gentle heat, or ensure the screwdriver fits properly.
Action Not Cycling Smoothly:
If the action isn’t cycling smoothly after reassembly, check for any binding, proper lubrication, and ensure the action bars are correctly seated in the forearm. Make sure the nut/screw is not too tight.
Other Issues:
If you encounter any other problems, refer to the Remington 870 manual or consult with a qualified gunsmith.
