BCM KMR Alpha 9" KeyMod Handguard Black Anodized AR-15

The BCM KMR Alpha 9" handguard transforms standard AR-15 platforms with precision-machined aluminum construction and authentic KeyMod attachment points. This handguard eliminates the bulk of traditional quad rails while maintaining superior mounting versatility for accessories.

What Makes This Different

Unlike standard plastic handguards, the KMR Alpha features 6061-T6 aluminum construction with integrated KeyMod slots at the 3, 6, and 9 o'clock positions. The free-floating design eliminates barrel contact pressure that can affect accuracy, while the slim 1.3" outer diameter provides comfortable grip ergonomics. BCM's proprietary barrel nut system ensures rock-solid lockup with minimal installation complexity.

Key Features

• Free-floating design eliminates barrel harmonics interference
• 6061-T6 aluminum construction with Type III hard anodizing
• KeyMod attachment points at 3, 6, and 9 o'clock positions
• Low-profile gas block compatible design
• Anti-rotation tabs prevent handguard movement under stress
• Slim 1.3" outer diameter for improved weapon handling
• Compatible with carbine and mid-length gas systems

Range testing demonstrates consistent accuracy improvements over standard handguards due to the free-floating barrel configuration. The KeyMod system accepts standard accessories including bipods, lights, and laser devices without additional rail sections. Weather resistance testing shows the hard anodized finish maintains integrity through temperature extremes and moisture exposure typical in field conditions.
