The BCM Nylon KeyMod Rail Section (brand part no. BCM-KMR-1913-N5-FDE) is a 5.5-inch Picatinny rail section built from lightweight, impact-resistant polymer for attaching non-load-bearing accessories to any KeyMod-interface handguard. Machined to Mil-Standard 1913 Picatinny Arsenal specifications with a snag-resistant profile, it uses corrosion-resistant stainless steel mounting hardware in a self-contained assembly, so there is no loose hardware to lose during installation. Finished in flat dark earth, it is intended for lights, sights, and other non-load-bearing accessories; BCM recommends its aluminum rail sections instead for load-bearing use, and torque on this nylon version should not exceed 20 in-lbs.
