The Magpul M-LOK Aluminum Rail Section (part no. MAG581-BLK) bolts directly onto any M-LOK-compatible handguard or forend, adding a short run of 1913 Picatinny rail exactly where you need it for a light, vertical grip, or other rail-mounted accessory. Magpul machines it from mil-spec anodized aluminum and beveled the ends to reduce snagging and eliminate sharp corners, so it stays comfortable under a support hand. All hardware needed for a direct attachment to either aluminum or polymer M-LOK handguards is included.
