Why Magazine Spring Upgrades Matter

As magazines go through repeated cycles of feeding, they experience stress from the spring compression and expansion. Over time, the spring can lose its tension, causing feeding issues, malfunctions, or failure to fully load rounds. Upgrading your magazine spring helps to:

  • Improve Feeding Reliability: A fresh, high-quality spring ensures that rounds are fed consistently and without interruption.

  • Increase Longevity: Magazine springs that are properly maintained or upgraded last longer, keeping your magazines in working order for more rounds.

  • Prevent Misfeeds: As springs weaken, they may fail to feed the last few rounds or cause misfeeds. Upgraded springs can prevent this, particularly in high-round count shooting.

Benefits of Magazine Spring Upgrades

Upgrading your magazine springs offers several advantages for both competitive and tactical shooters:

1. Consistent Feeding Performance

High-quality magazine springs help maintain the correct amount of tension as rounds are fed into the chamber. This ensures smooth, uninterrupted feeding, especially during rapid-fire or competition shooting.

2. Enhanced Reliability Under High-Round Counts

Magazine springs can wear out after extended use, causing feeding issues such as failure to lock the slide back or improperly loaded rounds. Upgraded springs ensure your magazine maintains reliable feeding performance, even during high-round count sessions.

3. Prevents Failures to Feed

Weak or old springs are one of the leading causes of failures to feed, especially in magazines with high capacities. A new, high-performance spring will prevent such issues by maintaining consistent tension and ensuring proper feed geometry.

4. Improved Magazine Longevity

Regular use of a magazine spring causes it to lose tension over time, but a high-quality upgraded spring lasts longer, reducing the need for frequent replacements. With proper maintenance, you can extend the lifespan of your magazines and keep them functioning optimally.

Types of Magazine Spring Upgrades

There are a variety of aftermarket magazine springs available to enhance your firearm’s reliability. Here are some of the most common options:

1. High-Quality Stainless Steel Springs

Stainless steel springs are known for their durability and corrosion resistance. They offer long-lasting tension and can withstand the stresses of high-round counts without losing effectiveness.

Benefits of Stainless Steel:

  • Long-lasting: Stainless steel is resistant to corrosion and lasts longer in demanding conditions.

  • Reliable Feeding: Stainless steel springs ensure consistent performance even after many cycles.

  • Corrosion-Resistant: Ideal for wet or humid environments, preventing rust and ensuring a smooth feed.

2. Heavy Duty Springs

Heavy-duty springs are designed for high-capacity magazines or firearms that experience rapid fire. These springs provide increased tension, ensuring that the last few rounds feed correctly, even under high stress.

Benefits of Heavy Duty Springs:

  • Increased Power: These springs provide more power to feed the last few rounds, especially in high-capacity magazines.

  • Better for High-Frequency Use: Heavy-duty springs are ideal for high-round count shooting, reducing feeding issues during competition or tactical scenarios.

3. Magpul or Enhanced Capacity Springs

Magpul and other brands offer springs designed to handle large-capacity magazines with ease. These springs are often used in magazines that hold more than 30 rounds and help to maintain consistent feeding.

Benefits of Enhanced Capacity Springs:

  • Specifically Designed for High-Capacity Magazines: These springs help prevent misfeeds and ensure reliability during rapid shooting.

  • Reduced Failure to Feed: Ideal for those using high-capacity magazines frequently, ensuring smooth cycling.

  2. Remove the Base Plate: Remove the base plate or floorplate of the magazine, either by pressing or sliding it off depending on your magazine design.

  3. Remove the Old Spring: Carefully slide the old magazine spring out of the magazine tube.

  4. Insert the New Spring: Place the new spring inside the magazine tube. Ensure the spring is correctly oriented, with the shorter end typically going into the base plate.

  5. Reassemble the Magazine: Replace the base plate or floorplate and ensure it is securely attached.

  6. Test the Magazine: Perform a function test to ensure the spring is seated properly and the magazine feeds correctly.
