The Remington 870 pump-action shotgun is a legendary firearm, known for its reliability and versatility. A key component to its smooth operation is the pump slide, or forend. Understanding how it works, troubleshooting common issues, and performing routine maintenance are crucial for ensuring your 870 functions flawlessly. This guide will cover everything from basic operation to advanced upgrades, providing insights for both novice and experienced users.
Understanding the Remington 870 Pump Slide Mechanism
The pump slide's primary function is to cycle the action of the shotgun, ejecting spent shells and chambering fresh rounds. This involves a complex interplay of parts: the slide itself, the slide release, the bolt, and the carrier. When you pump the slide, you're engaging this entire mechanism. A smooth, controlled pump is essential for reliable operation. A stiff or sluggish slide can indicate problems requiring attention.
Key Components and their Roles:
- Slide (Forend): The part you physically manipulate to operate the shotgun.
- Slide Release: Allows the slide to be detached for cleaning or maintenance.
- Bolt: The heart of the action, responsible for extracting, ejecting, and chambering shells.
- Bolt Carrier: Connects the bolt to the slide, translating the slide's movement into bolt operation.
Troubleshooting Common Remington 870 Pump Slide Problems
Several issues can affect the smooth operation of your Remington 870's pump slide. These range from simple malfunctions easily addressed with cleaning and lubrication to more serious problems requiring professional attention.
1. Stiff or Difficult Pump Action:
- Cause: Most often, this is due to dirt, debris, or lack of lubrication in the action. Dried lubricant can also contribute to stiffness.
- Solution: Thoroughly clean and lubricate all moving parts within the action. Pay close attention to the bolt, carrier, and slide rails. Use a high-quality gun oil designed for firearms.
2. Slide Binding or Sticking:
- Cause: This could be due to excessive fouling, damaged or bent parts (like the ejector or extractor), or improper lubrication.
- Solution: Carefully examine the action for any signs of damage or debris. Clean thoroughly and re-lubricate. If the problem persists, it may require a more in-depth inspection by a qualified gunsmith.
3. Shell Failure to Eject:
- Cause: This can result from weak or damaged extractors, excessive fouling, or improperly sized shells.
- Solution: Inspect the extractor for damage and ensure it's properly seated. Clean the chamber and ensure you are using ammunition appropriate for your firearm.
4. Slide Not Locking Open on Empty Magazine:
- Cause: This often points to a problem with the bolt stop mechanism or a damaged bolt.
- Solution: Check the bolt stop for proper function. If the issue persists, professional inspection is advisable.
Upgrading Your Remington 870 Pump Slide
While the standard Remington 870 pump slide is robust and reliable, many aftermarket options exist to enhance its performance and aesthetics. These upgrades can improve ergonomics, reduce friction, or simply personalize your firearm. Remember to ensure any upgrade is compatible with your specific model of Remington 870.
Popular Upgrades:
- Enhanced Slide Rails: These can reduce friction and improve the smoothness of the pump action.
- Ergonomic Forends: Many aftermarket forends offer improved grip and handling.
- Tactical Forends: Designed for specific tactical applications, these may incorporate features like Picatinny rails for mounting accessories.
Maintaining Your Remington 870 Pump Slide
Regular maintenance is crucial for ensuring your Remington 870 remains reliable. This involves regular cleaning, lubrication, and inspection of all moving parts.
Maintenance Schedule:
- After Each Use: Clean the action, removing any fouling or residue.
- Monthly: Thoroughly clean and lubricate all components, paying close attention to the slide and its related parts.
- Annually: Perform a more thorough inspection, checking for wear and tear on critical components.
By understanding the mechanics of the Remington 870 pump slide, addressing potential problems proactively, and performing regular maintenance, you can ensure your shotgun functions reliably and remains a valuable asset for years to come. Remember, if you are unsure about performing any maintenance or repairs, consult a qualified gunsmith.
