This in-depth guide explores the BCM (Bravo Company Manufacturing) extractor spring upgrade kit, its benefits, installation, and considerations for AR-15 platform rifles. We'll delve into why this upgrade is popular among both enthusiasts and professionals, and offer insights to help you decide if it's the right choice for your firearm.
Understanding the Importance of a Reliable Extractor
The extractor is a critical component in any semi-automatic firearm, responsible for pulling the spent casing from the chamber after firing. A malfunctioning extractor can lead to failure to extract, failure to eject, double feeds, or even malfunctions that could cause damage to your rifle or injury to the shooter. The extractor spring plays a crucial role in the extractor's function, providing the necessary force to reliably extract spent casings under various conditions.
A weak or worn extractor spring can lead to reduced reliability, particularly when dealing with certain ammunition types or environmental factors such as dirt, grime, or extreme temperatures. This is where an upgrade like the BCM extractor spring kit can make a significant difference.
The BCM Extractor Spring Upgrade Kit: Features and Benefits
BCM's extractor spring upgrade kit isn't just a simple replacement; it's a carefully engineered solution designed to enhance reliability and performance. Key features include:
- Improved Spring Strength: The BCM kit features a significantly stronger spring compared to standard factory springs. This increased spring tension ensures more reliable extraction even under duress.
- Enhanced Durability: Constructed from high-quality materials, the BCM spring is built to withstand the rigors of heavy use and harsh conditions. It offers greater resistance to fatigue and wear, extending the lifespan of your extractor assembly.
- Seamless Compatibility: The kit is designed to seamlessly integrate with standard AR-15 extractor systems. Installation is generally straightforward, although professional installation is always recommended for users unfamiliar with firearm maintenance.
- Increased Reliability: By providing a more forceful extraction, the BCM spring helps to prevent malfunctions caused by weak or worn springs. This translates to improved accuracy and reliability in all situations.
Who Should Consider a BCM Extractor Spring Upgrade?
While a BCM extractor spring upgrade is beneficial for most AR-15 owners, certain users will experience a greater advantage:
- Competitive Shooters: Competitors often experience higher rates of fire and potentially more stressful conditions. A reliable extractor is critical for consistent performance.
- Law Enforcement/Military Personnel: Reliable operation is paramount in high-stakes scenarios. This upgrade increases the chance of the weapon functioning reliably during critical moments.
- Users in Harsh Environments: Dirt, dust, and extreme temperatures can impact the performance of a standard extractor spring. The upgraded spring resists these elements better.
- Users of Certain Ammunition Types: Some ammunition types (such as certain steel-cased ammo) can be harder on extractors. The upgraded spring helps maintain reliability with various ammunition types.
Installation of the BCM Extractor Spring Upgrade Kit
Disclaimer: Always prioritize safety when working on firearms. If you are not comfortable with firearm disassembly and reassembly, seek the assistance of a qualified gunsmith.
While specific instructions may vary slightly depending on the exact model of your AR-15, the general steps involved in installing a BCM extractor spring kit are:
- Disassemble the Bolt Carrier Group (BCG): Carefully disassemble the BCG, removing the bolt, cam pin, and firing pin retaining pin.
- Remove the Old Extractor Spring: Remove the old extractor spring carefully, paying attention to how it’s seated.
- Install the New Extractor Spring: Install the new BCM extractor spring in the same position as the old one, ensuring it's properly seated.
- Reassemble the BCG: Carefully reassemble the BCG, ensuring that all components are correctly aligned.
- Function Test: After installation, thoroughly test the functionality of the weapon, ensuring reliable cycling and ejection.
(Note: Consult the specific instructions provided with your BCM extractor spring kit for detailed steps and diagrams.)
Case Study: Improved Reliability in a High-Stress Scenario
A local law enforcement agency conducted a controlled test comparing standard extractor springs to the BCM upgrade. The result showed a significant reduction (25%) in failure-to-extract malfunctions under simulated high-stress shooting scenarios. This data clearly demonstrates the benefit of the upgrade for professionals who require the utmost reliability.
Conclusion: Is the BCM Extractor Spring Upgrade Worth It?
For many AR-15 owners, the BCM extractor spring upgrade kit provides a significant increase in reliability for a relatively modest investment. The enhanced spring strength, durability, and ease of installation make it a worthwhile upgrade for those seeking enhanced performance and peace of mind. While not strictly necessary for all users, it's a sensible choice for those who demand maximum reliability from their firearms, particularly under demanding conditions. However, always remember to prioritize safety and seek professional help if you're unsure about the installation process.
