Build and finish
The AR-15 H2 Carbine Buffer is built to exacting standards, using aircraft-grade aluminum for its lightweight yet robust construction. The hard anodized finish provides an additional layer of protection against corrosion, ensuring longevity even in harsh environments. This buffer stands out for its precision tolerances, which are critical for maintaining smooth operation in demanding shooting scenarios.
Inside the buffer, a combination of steel and tungsten weights is carefully balanced to achieve the H2 designation. This configuration offers a midpoint between standard carbine buffers and heavier H3 buffers, making it versatile for a range of applications. The result is a component that delivers consistent performance without compromising on durability.
Compatible platforms
