The BCM Nylon KeyMod Rail Section (brand part no. BCM-KMR-1913-N3-FDE) gives AR-15 owners a lightweight, 3-inch Picatinny rail segment for mounting accessories to a KeyMod handguard. Built by Bravo Company Mfg to Mil-Standard 1913 Picatinny Arsenal specifications, it’s molded from impact-resistant polymer and finished in Flat Dark Earth to match tan and desert-toned builds. The self-contained assembly keeps all mounting hardware attached to the rail itself, so you won’t lose a screw mid-installation, and the snag-resistant profile keeps the section from catching on gear while still holding to mil-spec dimensions.
