The Indispensable Role of AR-15 Magazine Springs
The AR-15. It’s a firearm that has become a cornerstone of both recreational shooting and personal defense across the United States and increasingly globally. Its modular design and adaptability have made it incredibly popular, and at the heart of its functionality lies a seemingly simple, yet absolutely vital, component: the magazine. Within this magazine resides an unsung hero, the AR-15 magazine spring. This critical part is often overlooked, yet without it, your AR-15 transforms from a functioning firearm into a frustrating paperweight. This article will explore everything you need to know about AR-15 magazine springs, from their fundamental role to practical maintenance tips and troubleshooting advice. We’ll delve into their construction, the impact of a failing spring, and how to keep your rifle running smoothly.
The magazine of an AR-15 isn’t merely a container for holding ammunition. It’s a complex feeding system, and the AR-15 magazine spring is the driving force behind that system. Its job is deceptively simple: to consistently push rounds upwards into the chamber. Without this pressure, your rifle cannot function.
The primary function of the magazine spring is to provide the necessary force to elevate the cartridges within the magazine, ensuring they are correctly aligned and presented to the bolt for chambering. As each round is fired and the bolt cycles, the spring must continue to feed the next round. It has to work reliably to consistently provide this pressure. This force is what keeps the rounds from simply rattling around in the magazine. This consistent force also helps to prevent malfunctions that can quickly ruin a day at the range or, in a self-defense scenario, potentially endanger your safety.
A faulty or worn-out spring immediately creates problems. The most common consequence is feeding issues. These issues manifest in various ways: failures to feed (FTF), where a round doesn’t enter the chamber properly; double feeds, where two rounds attempt to enter the chamber at once, causing a jam; and failure to eject (FTE), where the empty case does not leave the chamber. All of these disrupt the firing cycle and prevent reliable operation. Reduced magazine capacity is another symptom; you may find that your magazine only holds a few rounds, even though it’s designed for more. Jamming, a frustrating and potentially dangerous situation, is also more likely with a compromised spring. This can halt your shooting and require immediate attention to clear the malfunction.
Exploring the Anatomy of Magazine Springs
So, what exactly is an AR-15 magazine spring made of? It may seem like a simple piece of wire, but its design and the materials used play a critical role in its performance and longevity.
At its core, the AR-15 magazine spring is typically a coil spring. The specific design, particularly the number of coils and the spring rate (the amount of force required to compress it a certain distance), is carefully engineered to provide the necessary pressure for reliable feeding. The spring is designed to compress and expand repeatedly without losing its elasticity.
The choice of materials impacts the durability and resistance to corrosion. The most common material is music wire or spring steel, selected for its excellent elasticity and ability to withstand repeated compression cycles. The steel is often heat-treated to increase its strength and durability, which helps ensure it continues to provide reliable function even under stress. Stainless steel is another popular choice, prized for its excellent resistance to corrosion. This is especially important if the rifle is used in humid environments, or if magazine maintenance is less than perfect. Stainless steel can resist the formation of rust and corrosion, preserving the functionality of the spring for much longer.
While the basic design of the spring is consistent, variations exist. Some springs might have slightly different coil spacing or overall lengths. The quality of manufacturing, including the precision of the coiling and the quality of the steel, also plays a significant role. Higher-quality springs are more likely to maintain their tension and deliver consistent feeding over a longer period, therefore making the use of a high-quality AR-15 magazine spring essential.
Factors Influencing the Lifespan and Performance of AR-15 Magazine Springs
The life of an AR-15 magazine spring isn’t indefinite. Several factors can influence its lifespan and overall performance. Understanding these factors will help you take steps to prolong your spring’s functionality and maintain the reliability of your firearm.
How frequently you use your rifle is a primary factor. Every time you load and unload a magazine, the spring is compressed and expanded. High-volume shooters, who regularly engage in activities like competitive shooting or extensive training, will naturally put more wear and tear on their magazine springs compared to those who only use their rifles occasionally.
The environment in which the rifle is stored and used also plays a role. Moisture is the enemy. Exposure to humidity can cause rust and corrosion, which will compromise the spring’s strength and functionality. Even exposure to salty air can have a damaging effect, potentially leading to rust. Extreme temperatures can also have an impact, with heat potentially degrading the spring’s temper and cold potentially making the spring more brittle.
The quality of the spring material is, of course, paramount. Lower-quality springs may be made from inferior materials or not properly heat-treated, making them more susceptible to premature failure. Investing in high-quality springs from reputable manufacturers is a good strategy to extend the life of your springs.
Proper magazine maintenance is vital. This includes cleaning the magazine regularly and ensuring that the spring is free from debris or contaminants. When a spring is contaminated with dirt or debris, it can affect its ability to compress and expand correctly. Keeping the spring lightly lubricated (with a dry lubricant like graphite or moly grease, for example) can also help, allowing it to move freely and reduce friction.
Recognizing and Addressing Spring-Related Issues
Knowing how to spot problems with your AR-15 magazine springs is essential. Early detection can prevent more serious malfunctions and ensure the continued reliable operation of your rifle.
Several telltale signs indicate that your magazine spring may be failing. As mentioned earlier, failure to feed (FTF) is a primary symptom. If a round doesn’t enter the chamber when you pull the trigger, the spring may be unable to provide the necessary force. Failure to eject (FTE) is another indicator. If the empty cartridge casing doesn’t leave the chamber after firing, the spring may not be properly feeding the next round, causing the casing to get stuck. Slow or erratic feeding is another sign. You may experience sluggish feeding or rounds jamming as they enter the chamber. Reduced magazine capacity can also signal a spring problem. Your magazine might not hold the full number of rounds it’s designed for. And finally, if the magazine fails to hold the bolt open after the last round is fired, the spring may not be providing the tension needed to lift the follower and engage the bolt catch.
Regular inspection is key. The best way to identify spring problems is to regularly disassemble and inspect your magazines. Start with a visual inspection, checking for rust, corrosion, or any signs of physical damage or deformation to the spring. Ensure the spring isn’t bent or twisted. Next, check the tension by hand. Does it feel weaker than it should? Does the spring feel “mushy”? If so, the spring is likely worn. Make sure the spring moves freely inside the magazine body. Sometimes debris can get lodged, preventing the spring from functioning properly.
Troubleshooting is usually straightforward. If you detect any problems, the first step is often to disassemble and thoroughly clean the magazine. Remove the spring and follower and inspect them for dirt, debris, or damage. Clean the magazine body with a suitable solvent. The spring might be cleaned or replaced, depending on its condition. Replacing the spring with a new one is the easiest and most reliable fix if you suspect a problem with the spring.
Maintaining and Replacing AR-15 Magazine Springs: A Practical Guide
Maintaining your magazines is a key element of responsible gun ownership. Regular maintenance, including periodic inspection and proper replacement, helps ensure your AR-15 magazine springs continue to function reliably and your rifle performs when it’s needed.
Magazine disassembly is the initial step in inspecting and cleaning. Always prioritize safety. Make sure your firearm is unloaded, with the magazine removed and the chamber clear. You’ll typically start by removing the base plate from the magazine body. Many magazine base plates are held in place with a locking plate or a similar mechanism. Carefully depress this locking mechanism to slide the base plate off the magazine. Be careful, because the spring is under tension and can launch the follower with significant force when the base plate is removed.
Carefully remove the spring and follower. Hold the magazine so the spring and follower don’t launch themselves. The spring and follower can be pulled out of the magazine body once the base plate is removed.
Cleaning and lubrication are next steps. Cleaning the magazine body is crucial for removing any dirt or debris. Use a solvent specifically designed for cleaning firearms to clean the interior and exterior of the magazine body. Allow the solvent to dry completely. Lightly lubricate the spring. Use a dry lubricant, such as graphite powder or a specialized firearm lubricant, to lightly coat the spring. This reduces friction and ensures smooth movement. Reassemble the magazine carefully. Reinsert the spring and follower into the magazine body, then replace the base plate, ensuring it is securely locked.
Spring replacement should be done if the spring is damaged, corroded, or no longer provides the necessary tension. Disassemble the magazine as described above. When choosing a replacement spring, select one that is specifically designed for your AR-15 magazine. Pay attention to the manufacturer and the material, such as stainless steel. Remove the old spring and install the new one, following the manufacturer’s instructions. Reassemble the magazine, making sure everything is correctly positioned.
