Removing the forend on a Remington 870 is a fundamental skill for any shooter who plans to maintain, clean, or modify their shotgun. This single action grants access to the critical action bars, springs, and bearings that allow the weapon to cycle reliably. While the process is straightforward, doing it correctly ensures the longevity of the firearm and prevents damage to the delicate components inside the receiver.
Understanding the Forend's Function
The forend is more than just a grip; it is a structural component that connects the receiver to the action. As the shooter fires, the bolt group travels rearward, and the forend moves with it via the action bars. This synchronized movement cycles the shell, ejects the spent casing, and chambers a new round. Because the forend is directly linked to the internal mechanism, removing it is the primary step for deep cleaning or repairing internal failures.
Tools and Preparation
Before beginning, ensure you are working in a safe environment with the shotgun unloaded. Visually and physically confirm the chamber and magazine tube are empty. Gather the necessary tools, which are minimal for most models. You will typically need a standard punch or a small screwdriver to drive the pivot pin. It is recommended to wear safety glasses to prevent injury from any spring tension or loose parts.
Step-by-Step Removal Process
The actual removal of the Remington 870 forend requires releasing the tension held by the recoil spring. Follow these steps carefully to avoid compressing the spring unexpectedly:
Locate the forend latch, which is usually found at the front of the receiver where the barrel meets the stock.
Pull the forend fully forward to engage the latch.
Look for the pivot pin securing the forend to the action.
Use a punch to drive the pin out of the receiver, being prepared for the spring to release its energy.
Carefully lift the forend away from the receiver, noting the position of the action bars and springs.
Handling the Action Assembly
Once the forend is removed, you will see the action bars, recoil spring, and the bolt carrier group. This assembly is under significant tension from the recoil spring. Never let the assembly snap back freely, as it can cause serious injury or disassemble the gun in an uncontrolled manner. If you are cleaning, you can now safely wipe down the rails and lubricate the moving parts. If you are inspecting for wear, examine the action bars for cracks or excessive play.
Reinstallation and Function Checks
Reinstalling the forend is essentially the reverse of removal, but it requires attention to detail to ensure smooth operation. As you slide the forend back onto the receiver, align the action bars with the grooves inside the forend. Insert the pivot pin and secure it firmly. Before closing the action, pull the trigger slightly (with the safety on) to ensure the action moves freely without binding. Finally, cycle the shotgun several times to confirm the feed ramp and extraction are functioning correctly.
Troubleshooting Common Issues
Occasionally, shooters encounter resistance when removing or installing the forend. This is usually caused by dried lubricant or debris packed into the action rails. If the pin feels stuck, do not apply excessive force; instead, check the latch mechanism to ensure it is fully disengaged. Another common issue is a loose forend, which can be resolved by tightening the pivot nut if the model utilizes one. Regular maintenance keeps these issues at bay and ensures the Remington 870 remains a reliable tool.
