Understanding the Inner Workings
Location and Function
At its core, the Remington 870 relies on a straightforward yet effective mechanism. Shells are loaded into a tubular magazine, typically positioned beneath the barrel. As the user cycles the pump action, a new shell is lifted from the magazine and chambered, ready to be fired. This transfer process is intricately linked to the Remington 870 magazine spring. Located within the magazine tube, this spring is essentially a long, coiled piece of metal, usually steel, that provides the necessary force to push the shells upwards towards the feed ramp. Its job is continuous: exerting pressure on the column of shells within the magazine, ensuring they are consistently presented for chambering. The strength and resilience of the spring directly affect how effectively the shotgun feeds ammunition. A weak or worn-out spring can lead to failures, while a strong, well-maintained spring will help the Remington 870 function flawlessly. Along with the spring, there are other important parts in this system, such as the magazine follower, the little disc that sits atop the shells, and the magazine cap, which keeps everything sealed.
Components and Materials
The spring itself, typically made from spring steel, is designed to withstand considerable compression and expansion over an extended period. However, repeated use, environmental factors, and simply the passage of time can take their toll. The shape of the spring, and how well it is able to maintain its tension, dictates the pressure it exerts. Its ability to maintain its shape, even after being compressed and released thousands of times, is essential to the operation of a Remington 870.
Identifying Potential Problems
While the Remington 870 magazine spring is built to last, it’s not invulnerable. Several issues can arise that compromise its performance. One of the most common is spring fatigue. Over time, the constant compression and expansion can weaken the spring, diminishing its ability to provide the necessary upward force. This fatigue can be subtle, gradually impacting feeding reliability without immediately being obvious. Other problems may include rust and corrosion, especially if the shotgun has been exposed to moisture or is not properly maintained. Rust can cause the spring to bind within the magazine tube, hindering its movement and compromising its ability to function properly. Debris, such as dirt, grit, and even remnants of cleaning products, can also accumulate within the magazine tube, interfering with the spring’s operation. These contaminants can restrict its movement, causing feeding problems.
Keeping It in Top Condition
Regular Inspection
Regular maintenance is key to ensuring that your Remington 870 magazine spring functions reliably. Inspection is the first step. The frequency of inspection depends on how often you use the shotgun. For those who shoot frequently, inspecting the magazine spring after every outing is a good practice. If you’re a less frequent shooter, inspecting it every few months, or before any critical use, is adequate. During inspection, carefully examine the spring for any signs of rust, corrosion, or physical damage. Look for any areas where the spring appears deformed or bent. Also, pay attention to the magazine tube itself. It should be clean and free of any obstructions. Run your finger inside the tube. Is it smooth, or does it feel gritty?
Cleaning and Lubrication
Cleaning and lubrication are also essential. The cleaning process itself doesn’t need to be overly complicated. You can use a cleaning rod and a brush, specifically designed for the gauge of your shotgun, to clean the magazine tube. Ensure you remove any debris. Use a solvent appropriate for firearms to remove any build up. After cleaning, apply a light coat of lubricant to the spring and the inside of the magazine tube. The correct lubricant is important, to protect the spring from corrosion and minimize friction. Gun oil or a specialized gun lubricant is typically recommended. Avoid using excessive amounts of lubricant, as this can attract dirt and debris. Wipe off any excess lubricant before reassembling the shotgun. Regular maintenance will greatly prolong the life of the Remington 870 magazine spring and contribute to the overall reliability of your firearm.
Removal and Reinstallation
Taking out the magazine spring to inspect or replace it might sound daunting but it is actually a relatively simple process. Begin by ensuring your Remington 870 is unloaded. Confirm that the chamber is clear by visually inspecting it. Then, remove the magazine cap. This is usually done by unscrewing it. Some models might have a detent or release mechanism, so check your owner’s manual if you’re unsure. Next, carefully remove the follower from the magazine tube. This can often be done by tilting the shotgun downwards to allow the follower to slide out. Once the follower is removed, the spring can be easily pulled out from the magazine tube.
When reinstalling the spring, carefully insert it into the magazine tube, ensuring that it’s properly seated. Make sure the spring is positioned so that it can exert pressure on the follower. Then, reinsert the follower and replace the magazine cap. Before heading to the range, test the function of the shotgun by cycling a few rounds through the magazine and ensuring it feeds smoothly. If you are working on the Remington 870 magazine spring, it is always recommended to take all the safety precautions necessary to safely handle the shotgun.
Deciding When It’s Time for a Change
When to Replace
The Remington 870 magazine spring isn’t a lifetime component. Like any part subjected to repeated stress, it will eventually wear out. It’s difficult to provide a specific timeframe for replacement, as this depends on usage frequency, ammunition used, and environmental factors. However, there are several indicators that signal the need for a new spring. The primary sign is any feeding problems, such as failures to feed, jams, or sluggish cycling. These issues suggest that the spring may no longer be providing sufficient force to move the shells. If you experience these malfunctions, it is recommended that the spring is the first component you evaluate for replacement.
Selecting a Replacement
Additionally, inspect the spring regularly, and replace it when you notice any physical damage, such as bending or rust. When the spring no longer springs, it should be replaced. Finally, for some, a preventive approach is best. Some shooters choose to replace the Remington 870 magazine spring every few years, or after a certain number of rounds fired. This can help to prevent potential malfunctions and ensure consistent reliability.
Choosing a Replacement Spring
OEM and Aftermarket Options
When the time comes to replace your Remington 870 magazine spring, several options are available. The original equipment manufacturer (OEM) springs are a reliable choice, as they are designed to fit and function perfectly in your shotgun. These springs offer consistent performance and are readily available from most gun stores or online retailers.
Aftermarket springs offer some alternative choices. Some aftermarket springs are designed to be heavier-duty, providing more upward force. These may be beneficial for some shooters, especially those who frequently use heavy loads or extended magazine tubes. When selecting a replacement spring, make sure it is specifically designed for your Remington 870 and its magazine configuration. Consider the materials used in the spring. Stainless steel springs are more resistant to corrosion than those made of carbon steel. The best spring, will depend on your specific needs and shooting style.

The Possible Benefits of Upgrading
Advantages of an Upgrade
While a standard, well-maintained Remington 870 magazine spring will provide reliable performance, some shooters opt to upgrade to a heavier-duty or a spring with special coatings. The primary benefit of upgrading is potentially increased reliability. A stronger spring can ensure more consistent feeding, especially when using heavier loads or extended magazine tubes. These upgrades can also help to reduce the chance of malfunctions, even under harsh conditions. A well-designed and properly installed upgraded spring can make the shotgun more resistant to malfunctions, which can be invaluable in any situation where the weapon needs to work.
Types of Upgraded Springs
Springs with specialized coatings or designs may further enhance reliability. These coatings can help to reduce friction within the magazine tube, promoting smoother cycling.
Troubleshooting the Most Common Problems
Failure to Feed
Even with proper maintenance, issues can arise. Troubleshooting starts with identifying the nature of the problem. If you’re experiencing a failure to feed, look at the spring. A weak spring will make it difficult for the rounds to get where they need to go. Remove the magazine spring and check for wear.
Jams and Other Issues
Jams can also be caused by the magazine spring. A jam is often an abrupt disruption of the shell’s movement through the system. Often, if a shell is not pushed firmly enough, a jam can occur. Again, it may be caused by the spring being worn out, or by a build-up of debris in the magazine tube. Cleaning the magazine, replacing the spring, and properly lubricating the system can eliminate jamming issues.
Some other potential problems might be a weak ejector spring, or even the ammunition itself being faulty. Make sure to isolate the spring issue and then try testing out all of your potential solutions.
