Introduction:
The Remington 870 is a legendary pump-action shotgun, known for its reliability and versatility. Whether you're a seasoned shooter or a new owner, understanding how to properly disassemble and clean your Remington 870 is crucial for maintaining its performance and longevity. This in-depth guide will walk you through the process, providing step-by-step instructions and helpful tips. We'll cover both field stripping (for basic cleaning) and a more complete disassembly for a thorough cleaning or repairs. Remember, safety is paramount. Always ensure the firearm is unloaded and the action is open before beginning any disassembly.
Field Stripping Your Remington 870
This section covers the basic disassembly for routine cleaning. It's a simple process that anyone can master with a little practice.
Tools You'll Need:
- A clean work surface
- A gun cleaning mat or towel
- A punch (optional, but helpful for removing the trigger group pin)
- A cleaning rod and patches
Steps:
- Safety Check: Verify the firearm is unloaded. Visually inspect the chamber and magazine tube.
- Open the Action: Work the action to ensure it's open.
- Remove the Forend: Push the forend release button (usually located on the bottom of the receiver) and slide the forend off the barrel.
- Remove the Barrel: Rotate the barrel slightly to clear the locking lugs, then lift the barrel straight up and off the receiver. Note: Some variations may require a slight forward push before lifting.
- Remove the Bolt: Pull the bolt straight back and remove it from the receiver.
- Cleaning: Thoroughly clean all parts using a suitable cleaning solvent and lubricant. Pay close attention to the bolt, barrel, and receiver.
Complete Disassembly of the Remington 870
This section describes a more extensive disassembly, suitable for thorough cleaning or repairs. It requires a bit more patience and attention to detail. Caution: This level of disassembly might void your warranty if performed improperly.
Tools Needed (in addition to those listed above):
- A screwdriver (appropriate size for your specific model)
- Possibly a wrench (depending on the model and what you need to repair/replace)
- A small container for storing small parts
Steps:
- Field Strip the Shotgun: Follow the steps in the "Field Stripping" section above to remove the barrel, forend, and bolt.
- Remove the Trigger Group: Locate the trigger group pin (usually positioned at the rear of the receiver). You can carefully drive it out with a punch, working from the left side of the receiver. This will release the trigger group. Be extremely careful not to damage any small parts.
- Disassemble the Trigger Group (Optional and Advanced): Once removed, the trigger group can be further disassembled, but this is generally only necessary for advanced repairs. Consult a detailed schematic or a qualified gunsmith for guidance if you are attempting this.
- Cleaning and Reassembly: Clean each component thoroughly. Reassembly is essentially the reverse of disassembly. Pay close attention to how each part fits together, and ensure all parts are correctly aligned before continuing. Refer to exploded diagrams if necessary.
Troubleshooting and Common Issues
- Failure to function: This can be caused by several factors, including dirty parts, worn parts, or ammunition issues. Carefully inspect all parts during disassembly, and replace worn or damaged components as needed.
- Jamming: Jams can be caused by a variety of problems, from incorrect ammunition to issues with the bolt or magazine tube. A thorough cleaning often resolves these issues.
- Extracting and Ejecting Problems: This can stem from problems with the extractor, ejector, or shell stop. These components should be carefully inspected and cleaned.
Safety Precautions
- Always treat every firearm as if it were loaded.
- Always point the muzzle in a safe direction.
- Never put your finger on the trigger until you are ready to shoot.
- Always be sure of your target and what is beyond it.
- Wear appropriate eye and ear protection when handling firearms.
- If you are unsure about any step, consult a qualified gunsmith.
Conclusion
Disassembling your Remington 870, whether for basic cleaning or more in-depth maintenance, is a valuable skill for any responsible firearm owner. By following these steps and adhering to safety precautions, you can keep your shotgun in top condition and ensure its continued reliable performance. Remember, if you're uncomfortable with any step of this process, consulting a qualified gunsmith is always recommended. The safety of yourself and others is paramount.
