The Magpul M-LOK Aluminum Rail (brand part no. MAG583-BLK) is a black, 9-slot 1913 Picatinny-spec rail section built for any M-LOK-compatible handguard or forend. It gives you a short run of Picatinny rail exactly where you need it for mounting lights, vertical grips, or other rail-mounted accessories, without running a full-length rail down the handguard. Magpul machines the section from mil-spec anodized aluminum and bevels the ends to eliminate sharp corners and reduce snagging on gear or clothing. All hardware needed to attach it directly to M-LOK slots on either aluminum or polymer handguards and forends is included.
