For decades, this pump-action firearm has been a trusted companion for law enforcement, hunters, and home defenders alike. A key component contributing to the 870’s legendary reputation is its robust and efficient operating mechanism. At the heart of this mechanism lies the **Remington 870 Forend Tube Assembly**, a critical assembly that drives the cycling of the action, allowing for rapid and reliable firing. This comprehensive guide will delve into every facet of the **Remington 870 Forend Tube Assembly**, providing you with the knowledge you need to understand, maintain, and, if necessary, repair this essential part of your firearm.
Understanding the Importance
The **Remington 870 Forend Tube Assembly** isn’t just a collection of parts; it’s an engineered system working in perfect concert. Its proper function dictates the speed at which you can reload and fire. Without it, the 870 is a single-shot, which drastically reduces its practical usefulness. Understanding the anatomy of the forend tube assembly is the first step toward appreciating its importance. Let’s take a look at the major components.
Anatomy of the Forend Tube Assembly
The Forend Tube
The forend tube itself is the backbone of the system. This sturdy cylindrical piece provides a housing for other vital parts and serves as the anchor for the action bars. It is often threaded to accept the forend nut, which secures the entire assembly to the receiver. The tube is generally made of steel and designed to withstand the stresses of repeated cycling and the occasional bumps and scrapes.
Action Bars
Next in line are the action bars. These are the long, slender metal rods that connect the forend to the bolt. As the forend is pumped back and forth, these bars pull the bolt rearward, ejecting the spent shell, and then push the bolt forward, chambering a fresh round. The action bars are crucial to the smooth and dependable operation. Without them, the gun simply won’t function.
The Forend Nut
Then, we have the forend nut. This large, usually knurled, nut threads onto the forend tube and is responsible for securing the forend, along with the action bars, to the receiver. The nut needs to be tightened to a specific torque to ensure proper function, while not over-tightening and damaging the assembly. This nut is a critical fastener.
Shell Carrier
The shell carrier is another integral piece. This mechanism is responsible for lifting each new shell from the magazine tube and positioning it for chambering. The carrier is moved by the bolt assembly, which is in turn moved by the action bars.
The Forend
Finally, we have the forend, sometimes referred to as the slide handle. This is the grip that the shooter holds and manipulates to cycle the action. It’s often made of wood or synthetic material and provides a comfortable and secure point of contact. The forend is directly connected to the action bars, and the movement of the forend directs the operation of the action.
Functionality and Importance
How the Assembly Works
This assembly isn’t just about a bunch of parts slapped together. The **Remington 870 Forend Tube Assembly** provides a means to transform human motion into an efficient machine. The forend, when moved backward, draws the action bars rearward. The action bars then pull the bolt to the rear, extracting the spent casing from the chamber and ejecting it. Simultaneously, the action bars push the shell carrier down and the shell stop out of the way. As the forend is pushed forward, the action bars push the bolt forward. This action strips a fresh shell from the magazine tube, pushing it into the chamber, and locking the bolt in place. It’s a seamless, reliable process honed over decades of production. This entire operation requires a perfect balance of timing and force, and the **Remington 870 Forend Tube Assembly** makes this cycle possible.
The Importance of Proper Functioning
A properly functioning forend tube assembly is paramount for the reliable operation of your shotgun. Any malfunction in this assembly can bring the entire operation to a screeching halt. A failure could prevent your firearm from firing, or even worse, cause a dangerous malfunction. That’s why it’s so important to understand how to diagnose and repair any problems you might encounter. Without a properly working assembly, you’ll have nothing but a paperweight.
Installation and Removal
Safety Precautions
When we look into installation and removal, we see that the process demands careful attention. Before you begin, ensure the firearm is completely unloaded. Point the muzzle in a safe direction, and visually and physically inspect the chamber and magazine tube to confirm there are no rounds present.
Tools Needed
To remove the **Remington 870 Forend Tube Assembly**, you typically need a few basic tools. You’ll need a wrench, usually a specific size to fit the forend nut. You may also need a small punch to remove the action bar from the bolt.
Removal Steps
First, unscrew the forend nut. You may need to apply some force, but be careful not to damage the threads on the forend tube. Next, carefully slide the forend and the action bars forward, away from the receiver. Once the forend is removed, you may need to use a punch to separate the action bars from the bolt.
Installation Steps
Installing a new forend tube assembly is generally the reverse of the removal process. Ensure all components are clean and lubricated. Attach the action bars to the bolt assembly. Slide the forend, along with the action bars, back onto the magazine tube. Tighten the forend nut, using the appropriate wrench, to the recommended torque specification, typically around 20-25 foot-pounds. Make sure the assembly moves smoothly and freely; there should be no binding or excessive resistance.
Common Problems and Troubleshooting
Common Issues
Even the most well-made components can encounter problems over time. The **Remington 870 Forend Tube Assembly** is no exception. One of the most common issues is wear and tear on the action bars. Constant use and stress can cause them to bend, break, or become damaged. A loose forend nut is another common problem; this can lead to the forend rattling and the action malfunctioning. The forend tube itself can be damaged if it’s impacted, and the assembly can also suffer from rust or corrosion, particularly if the shotgun is exposed to the elements or improperly stored.
Troubleshooting Tips
To address these problems, regular inspection is key. Inspect the action bars for any signs of bending, cracking, or wear. Check the forend nut regularly to ensure it remains properly tightened. Clean and lubricate the entire assembly after each use, or at a minimum, every time the gun is cleaned. If you notice any problems, address them immediately.
For a loose forend nut, simply tighten it to the correct torque specification. If you find rust or corrosion, carefully clean the affected components with a suitable gun cleaner and lubricant. Replace any damaged components promptly, or the performance will deteriorate. If the action is binding or sticking, you may need to disassemble the assembly and identify the source of the friction. It could be a burr on a part, or it could be the need for more lubrication.
