The Remington 870 shotgun, a legendary firearm known for its reliability and versatility, relies on a seemingly simple yet crucial component: the magazine spring. This spring, responsible for feeding shells smoothly and consistently, can be the difference between a successful hunt or a frustrating malfunction. This comprehensive guide will explore the Remington 870 magazine spring, its function, common problems, and how to replace it. Understanding this critical part ensures your Remington 870 remains a dependable tool.
Understanding the Remington 870 Magazine Spring's Role
The magazine spring, located within the Remington 870's magazine tube, is a powerful compression spring. Its primary function is to apply constant upward pressure on the shotgun shells, forcing them forward towards the carrier and action when the action is cycled. This constant pressure is vital for reliable feeding, particularly during rapid firing. Without a properly functioning magazine spring, the shells might not feed reliably, leading to jams or misfires.
How the Spring Works in Conjunction with other Parts
The spring interacts with several other components:
- Magazine Tube: This steel tube houses the spring and shells. Its smooth interior is crucial for unobstructed shell movement.
- Follower: This plastic or metal part sits atop the shells, compressing the spring and preventing the shells from falling out. A damaged or worn follower can contribute to feeding issues.
- Shell Stop: Located at the magazine tube opening, this part prevents shells from being inadvertently ejected. It works in coordination with the spring and follower.
- Action Bar: The action bar interacts with the shells, pushing them into the chamber when the gun is cycled.
Signs of a Weak or Broken Remington 870 Magazine Spring
A weakening or broken magazine spring manifests in several ways:
- Feeding Issues: This is the most common sign. Shells may fail to feed consistently, resulting in jams. You might experience difficulty loading shells or observe shells sticking halfway into the magazine tube.
- Weak Shell Ejection: While not always directly related, a weak spring can sometimes affect shell ejection force.
- Difficult Loading: Loading shells might require excessive force.
Diagnosing and Replacing Your Remington 870 Magazine Spring
Before attempting a repair, always ensure the firearm is unloaded and safely handled. Improper handling can lead to serious injury.
Step-by-Step Replacement Guide
-
Unloading the Shotgun: Completely unload the shotgun. Visually inspect the chamber and magazine tube to confirm it's empty.
-
Removing the Magazine Cap: Using a suitable tool (often a wrench or screwdriver), carefully remove the magazine cap.
-
Removing the Spring and Follower: Once the cap is removed, the spring and follower will likely come out. If they don't, gently guide them out. Be mindful of the spring's force.
-
Inspecting the Spring: Examine the spring for any signs of damage, such as cracks, breaks, or excessive wear. Compare it to a new spring for reference. A severely weakened spring will appear less taut and less tightly coiled.
-
Installing the New Spring and Follower: Place the new spring and follower back into the magazine tube. Ensure the follower sits correctly.
-
Reattaching the Magazine Cap: Securely attach the magazine cap.
Choosing the Right Replacement Spring
Using the correct spring is crucial. Purchase a Remington 870 magazine spring specifically designed for your model of shotgun. Using an incorrect spring can lead to malfunctions or damage to your firearm.
Note: While you can find aftermarket springs, stick to reputable brands to ensure quality and reliability.
Case Study: A Hunter's Misfire
A seasoned hunter experienced repeated feeding issues during a crucial hunting trip. After initially suspecting ammunition problems, he meticulously checked his Remington 870 and discovered a broken magazine spring. The replacement cost was minimal, but the downtime and potential loss of a hunting opportunity highlighted the importance of regular inspection and timely maintenance.
Conclusion: Maintaining Your Remington 870
The Remington 870 magazine spring is a small but vital part of this reliable shotgun. Regular inspection and timely replacement prevent malfunctions that can lead to frustration and lost opportunities. By understanding its function and how to address issues, you can ensure your Remington 870 remains a dependable companion for years to come. Remember always to prioritize safety and consult a qualified gunsmith if you are unsure about any repair procedures.
