The Remington 870, a legendary pump-action shotgun, is renowned for its reliability and robust design. However, like any firearm, understanding its internal workings, particularly the trigger assembly, is crucial for safe and effective operation. This guide delves into the Remington 870 trigger assembly, providing detailed information for both experienced shooters and those new to firearm maintenance.
Understanding the Remington 870 Trigger Mechanism
The Remington 870's trigger mechanism is relatively straightforward, but precision is key when disassembling and reassembling it. The core components include:
- Trigger: This is the component you pull to fire the shotgun.
- Hammer: This strikes the firing pin, igniting the primer.
- Sear: This engages the hammer, preventing accidental discharge.
- Disconnector: This prevents the gun from firing more than one shot per trigger pull.
- Trigger spring: This provides the necessary tension for trigger operation.
- Hammer spring: This powers the hammer's movement.
- Safety: This blocks the trigger mechanism, preventing accidental firing. (Note: Some models feature a crossbolt safety, while others use a tang safety.)
Identifying Parts and their Function
Before attempting any disassembly, it is crucial to completely unload the firearm and visually inspect each part. A clear understanding of each component’s function prevents accidental damage or misassembly. Reference a detailed exploded parts diagram from a reputable source (such as a Remington manual or a gunsmithing guide) to aid in identification. Pictures are invaluable!
Disassembling the Remington 870 Trigger Assembly: A Step-by-Step Guide
Disassembling the Remington 870 trigger assembly requires careful attention to detail. Improper disassembly can damage the firearm and compromise its safety. If you are unsure about any step, consult a qualified gunsmith.
Disclaimer: This guide provides general information. Specific steps may vary slightly depending on the model and year of manufacture. Always consult a qualified gunsmith or refer to your firearm's manual before performing any maintenance or repairs. Safety should always be your top priority.
Tools Needed:
- Gunsmithing screwdriver set (appropriate sizes for Remington 870 screws)
- Small punch or pick (for gently prying components)
- Clean workspace
- Container to hold small parts
Steps (General Outline - Specific steps will vary based on model):
- Ensure the firearm is unloaded. Visually inspect the chamber and magazine tube.
- Remove the stock. This usually involves removing a few screws securing the stock to the receiver.
- Remove the trigger group. This often involves removing pins and carefully separating the group from the receiver. (Consult a detailed diagram for your specific model.)
- Separate the individual components. Carefully separate the trigger, hammer, sear, disconnector, and springs. Take photos or make detailed notes of the arrangement.
- Clean and inspect. Clean all components with a gun cleaning solvent and brush. Check for wear or damage.
Reassembling the Remington 870 Trigger Assembly
Reassembly is the reverse of disassembly. It's crucial to follow the same steps in reverse order, ensuring each component is correctly seated and secured. Again, a detailed diagram is invaluable. Double-check each part's placement before proceeding.
Common Issues and Troubleshooting
- Trigger pull is too heavy or too light: This can often be addressed by adjusting the trigger spring tension. However, this requires experience and caution.
- Trigger malfunctions: If the trigger fails to function properly, the problem might lie in a damaged or improperly installed component. Professional help is advisable.
- Safety issues: Any safety-related problems necessitate immediate professional attention. Never attempt to repair a safety mechanism yourself unless you're a certified gunsmith.
Conclusion
The Remington 870 trigger assembly is a complex system requiring a thorough understanding for safe and effective operation. This guide offers a general overview. Always prioritize safety and consult a qualified gunsmith if you are unsure about any aspect of disassembly, cleaning, or repair. Improper handling can lead to serious injury or damage to your firearm. Remember: Safety First.
