The 5.5" BCM Gunfighter KeyMod rail section with 11 slots allows for the addition of a long stretch of MIL-STD-1913 Picatinny rail to KeyMod interface handguards, for mounting flashlights, grips, bipods, and other accessories.
The body is made of hard-anodized aircraft-grade aluminum alloy, and the mounting hardware is made of corrosion-resistant stainless steel. The snag-resistant profile still meets MIL-STD-1913 specifications, and the hardware is captured on the section so as not to lose components during installation.
