Understanding the Unsung Hero: The 930 Magazine Tube Spring
The Basics
The Mossberg 930: a name that resonates with shotgun enthusiasts across the globe. Known for its rugged reliability, ease of use, and versatility, it’s a favorite for everything from hunting and home defense to competitive shooting. But even the most dependable firearm has its critical components, and one of the most vital, often overlooked elements of the 930’s smooth operation is the **930 magazine tube spring**. This article is your comprehensive guide to understanding, maintaining, and ensuring the optimal performance of your 930’s feeding system, specifically focusing on that indispensable little piece of coiled steel.
The **930 magazine tube spring** isn’t just a piece of metal; it’s the engine that keeps your shotgun running. It’s the relentless force that drives the ammunition into the chamber, ensuring a consistent and reliable feeding cycle. Let’s delve into its function, location, and the vital role it plays in your shooting experience.
The heart of the matter lies within the magazine tube itself. The **930 magazine tube spring** resides within this long cylindrical housing, nestled directly beneath the follower. When you load your 930, the spring is compressed as the shells enter the magazine. As each round is chambered, the spring decompresses, relentlessly pushing the next round upward, ready to be fed into the chamber. This is its primary function: to ensure each cartridge is readily available for feeding, shot after shot. It’s a simple mechanism, but absolutely essential.
These springs are generally constructed from robust materials, with high-quality steel being the predominant choice. This is due to the need for enduring compressive strength and resistance to wear. It needs to withstand countless compressions and expansions, enduring the harsh environment inside the magazine tube, where friction, debris, and the occasional cleaning solvent can all take their toll.
The continued effectiveness of your **930 magazine tube spring** directly translates to the enjoyment and safety of shooting. A properly functioning spring means reliable feeding. Without it, you’re facing potential jams, failures to feed, and, at worst, rendering your shotgun useless in a critical situation. It is the unsung hero of a properly functioning Mossberg 930.
Identifying Potential Issues: When Your 930 Magazine Tube Spring Needs Attention
Common Symptoms
Just like any mechanical part, the **930 magazine tube spring** is subject to wear and tear. Recognizing the telltale signs of a failing spring can save you frustration and potentially prevent more serious issues. Here are some common indicators that your spring might be on its way out.
One of the most obvious symptoms is a failure to feed. This is when the shotgun fails to chamber a round properly, often resulting in a jam. You might experience this with the first round, or after a few shots. The spring is not delivering enough force to push the round out of the magazine and into the chamber.
Sometimes, the problems are more subtle: intermittent feeding problems. The shotgun might feed some rounds perfectly and then falter on others. This erratic behavior could be due to a spring that’s losing its strength or has become slightly damaged. It’s trying its best, but can’t handle the demands.
Another common sign of trouble is a reduced magazine capacity. If your 930’s magazine consistently holds fewer rounds than it should, the spring might not be strong enough to compress fully. It’s struggling to accommodate the number of rounds it’s designed to hold.
Difficulty loading cartridges into the magazine can also signal problems. The spring, in good condition, offers some resistance as you load rounds. If it feels unusually hard to load, or if the shells seem to be jamming, it could be a sign that the spring is beginning to fail.
Inspection and Troubleshooting
So, how do you know for sure? Start with a quick visual inspection. Carefully disassemble the magazine tube (more on that later). Look for any obvious signs of damage. Is there rust or corrosion? Are there kinks or bends in the wire? Do the coils appear to be compressed or stretched?
Beyond visual inspection, you should always include a functionality test. With the magazine tube disassembled, attempt to compress the spring manually and observe its action. Does it rebound readily and smoothly? Does it feel like it has the necessary strength to push the follower without hesitation? These things provide a good indication.
Before you consider replacement, however, make sure you rule out other potential causes of feeding problems. A thorough cleaning of the magazine tube is crucial. Debris, dirt, or even old lubricant can impede the spring’s movement. Use a suitable solvent and a cleaning rod or brush to ensure the tube is clear of obstructions. Also, check the follower itself for damage or wear. Ensure it’s traveling freely within the tube.
Replacing Your 930 Magazine Tube Spring: A Step-by-Step Guide
Tools and Preparation
If your **930 magazine tube spring** is showing signs of failure, replacement is usually the best course of action. It’s a straightforward process that can be done at home with the right tools and a little bit of patience. Here’s how to do it:
First, gather your necessary tools and materials. You will need a new **930 magazine tube spring**, and make sure it is compatible with your model (more on that later). Gather cleaning supplies, including a suitable solvent, a cleaning rod or brush, and some clean cloths. A screwdriver or other tools for disassembly are also required. Lastly, consider wearing safety glasses to protect your eyes.
The Replacement Process
Always prioritize safety. Before you begin, ensure your shotgun is completely unloaded. Remove the barrel and forend. This typically involves unscrewing the magazine cap and then separating the barrel assembly from the receiver. With the gun unloaded, proceed to remove the magazine tube from the receiver. Many models have a threaded connection, or it may have a retaining pin or clip. Consult your owner’s manual for the specific instructions. If necessary, use the correct tools to loosen or remove these items.
With the magazine tube removed, you’re ready to remove the old spring. This usually involves compressing the follower and retaining clip. Take precautions when releasing the spring. It can be under pressure, so control its release carefully.
Now, thoroughly clean the interior of the magazine tube. Remove any debris or old lubricant. A clean tube allows for better spring performance and prevents future problems. Use your cleaning solvent and brush, and be sure to remove all traces of the cleaning agent.
Carefully install the new spring into the magazine tube. Insert it in the correct direction. The spring should fit snugly within the tube and should slide easily. Compress it to place the follower into the tube and secure the retaining clip. Ensure that the clip is positioned correctly.
Reassemble the magazine tube to the receiver. Re-install the barrel and forend. This should be done carefully, and ensure that all parts are correctly positioned.
Before you head to the range, perform a function test. Load a few dummy rounds into the magazine and cycle the action a few times to ensure that the shotgun feeds and ejects properly. Observe the action. If it’s smooth and reliable, you’re ready to go. If not, review your work.
The Power of Upgrade: Enhancing Your 930 Magazine Tube Spring
Upgrade Options
While a standard **930 magazine tube spring** is perfectly functional, you can explore options for upgrading to improve reliability or performance. There are several spring options available that can give you an added advantage.
One of the more popular upgrades is choosing a spring made from different material, or with an improved design. Several manufacturers offer springs made from improved spring steel. These springs are often designed to be more durable and provide more consistent force over time.
For those seeking to increase their ammunition capacity, an extended magazine tube spring is a must. Extended magazine tube springs are designed to work with extended magazine tubes. This will give you a higher round capacity than standard.
Things to Consider
When considering upgrades, compatibility is key. Make sure the new spring is designed to fit the exact specifications of your 930 model. Incompatible springs will not function correctly and could potentially damage your firearm. Also, be aware of any local or federal regulations regarding magazine capacity.
