Frequently Asked Questions

What causes extraction and ejection failures in an AR-15?

Extraction and ejection failures in AR-15 pattern rifles are often caused by worn-out extractor springs and O-rings. These components lose their tension and effectiveness over time, typically after thousands of rounds, leading to improper gripping and ejection of spent casings.

How do you install the BCM Extractor Spring Upgrade Kit?

Installation involves field stripping the AR-15 bolt, removing the extractor pin, replacing the old spring and O-ring with the new BCM components, and then carefully reinserting the extractor pin, which will require more force due to the upgraded spring's tension.

What are the benefits of the BCM Extractor Spring Upgrade Kit?

The BCM Extractor Spring Upgrade Kit offers improved reliability by ensuring consistent and forceful extraction and ejection of spent casings. Made from durable chrome silicon, the spring provides longer service life and maintains tension better than standard springs, preventing common malfunctions.

Is the BCM Extractor Spring Upgrade Kit expensive?

No, the BCM Extractor Spring Upgrade Kit is very affordable. A 3-pack is typically priced around $14.95, making it a cost-effective solution for enhancing the reliability of your AR-15 platform firearms.
