MDT 6.5-Inch M-LOK Picatinny Rail with Flush Cup Sling Mount

The MDT 6.5-Inch M-LOK Picatinny Rail with Flush Cup Sling Mount (part no. 103143-BLK) bolts onto any M-LOK compatible forend, sold by MDT. It converts a 6.5-inch section of M-LOK slots into a standard Picatinny rail, giving shooters a mounting surface for lights, lasers, bipods, or other Picatinny-interface accessories. Built into the same section is a flush cup sling mount, adding a quick-detach sling attachment point without needing a separate hardware purchase. Machined as a single rigid piece rather than a flexible rail, it holds zero for mounted optics or accessories under recoil. This combination piece is a practical way to add both accessory rail space and a sling point to an M-LOK-equipped rifle in one part.
