The Magpul M-LOK Aluminum Rail Section (Magpul part no. MAG582-BLK) is a 7-slot rail that bolts directly to any M-LOK-compatible hand guard or forend and presents a 1913 Picatinny-spec surface for mounting lights, vertical grips, and other rail-mounted accessories. Magpul machines it from mil-spec anodized aluminum and bevels the ends to cut down on snagging and sharp edges. It works on either aluminum or polymer M-LOK hand guards, and all the hardware needed to attach it directly to the M-LOK slots ships in the box. At 3-1/8 inches long, it’s sized to add a Picatinny mounting section exactly where it’s needed without covering the whole hand guard.
