Product Summary
The AR-STONER AR-15 Carbine Flat Wire Buffer Spring is an ideal upgrade for custom AR-15 builds looking for enhanced reliability. Constructed from cryo-cycled 17-7 ph steel, this spring is designed to outlast stock versions while increasing the overall service life of the platform. It improves the shooting cycle by increasing bolt load for more positive feeding and decreasing compression force. Additionally, the design reduces system vibration and eliminates the distracting ‘twang’ sound common in standard springs, allowing for faster follow-up shots.
