The Remington 870 pump-action shotgun is a legendary firearm, renowned for its reliability, versatility, and ease of maintenance. A critical component of its operation is the pump slide, which cycles the action, ejecting spent shells and chambering fresh ones. Understanding the Remington 870 pump slide, its function, potential issues, and maintenance is crucial for any owner. This guide delves deep into the intricacies of this vital part.
Understanding the Remington 870 Pump Slide Mechanism
The pump slide, also known as the forearm or slide assembly, is more than just a handle; it's the heart of the 870's action. Its movement controls the entire cycling process. When you pump the slide, you're initiating a sequence of events:
- Shell Ejection: The rearward movement of the slide extracts the spent shell casing from the chamber.
- Bolt Operation: The slide's movement operates the bolt, which unlocks from the barrel and retracts.
- Chambering: The forward movement of the slide feeds a new round from the magazine tube into the chamber.
- Bolt Locking: The bolt locks into place, ensuring a safe and secure firing position.
This seemingly simple process is a marvel of mechanical engineering, requiring precise tolerances and smooth operation. The pump slide itself is a complex assembly involving several smaller components including the slide itself, the slide release, and the various internal springs and linkages.
Common Issues with Remington 870 Pump Slides
While the 870 is known for its reliability, issues with the pump slide can occasionally arise. These can range from minor inconveniences to malfunctions that prevent proper firearm operation. Here are some common problems:
- Sticking or Binding: Dirt, debris, or improperly lubricated parts can cause the slide to stick or bind during operation. This often requires cleaning and lubrication.
- Slide Release Issues: The slide release mechanism, responsible for holding the slide open after the last round is fired, can malfunction, preventing the slide from being released easily.
- Damage to Components: Rough handling or improper use can lead to damage to the slide, internal components, or the connecting parts. This often necessitates repair or replacement.
- Loose or Worn Parts: Over time, wear and tear can loosen or damage components within the slide assembly, impacting its smooth operation. Regular inspection and maintenance can mitigate this.
Troubleshooting & Maintenance
Addressing issues with your Remington 870 pump slide often involves a combination of troubleshooting and preventative maintenance.
1. Cleaning and Lubrication: Regularly cleaning and lubricating the slide assembly is paramount. Use a quality gun cleaning solvent and lubricant specifically designed for firearms. Disassemble the slide (refer to your owner's manual), clean all components thoroughly, and re-lubricate before reassembly.
2. Inspection for Damage: Regularly inspect the slide and its components for any signs of damage, such as cracks, bends, or excessive wear. Replace any damaged parts immediately.
3. Addressing Specific Issues: If you encounter specific issues like sticking or binding, carefully examine the slide and its interactions with other parts to identify the source of the problem. This may require additional troubleshooting or the assistance of a qualified gunsmith.
4. Replacing Worn Parts: Over time, certain parts within the slide assembly may wear out. Replacing these parts is crucial for maintaining the smooth and reliable operation of your 870.
Case Study: A Binding Pump Slide
A recent customer reported a binding pump slide on their Remington 870. After inspecting the firearm, it was discovered that excessive carbon buildup and lack of lubrication were the culprits. A thorough cleaning, lubrication with a quality gun oil, and reassembly resolved the issue. This emphasizes the importance of regular maintenance.
Conclusion:
The Remington 870 pump slide is a crucial component of this iconic shotgun. Understanding its function, potential issues, and how to maintain it is vital for safe and reliable operation. Regular cleaning, lubrication, and inspection are key to preventing problems and ensuring your 870 continues to function flawlessly for years to come. If you encounter persistent issues, don't hesitate to consult a qualified gunsmith. Remember always to follow all safety precautions when handling firearms.
