Description
The MDT M-LOK Picatinny Rail adds a MIL-STD-1913 / STANAG 4694 rail section to any M-LOK forend or buttstock for bipods, lights, sling mounts and other Picatinny accessories. This is the 5 in length (part 103142-BLK), machined from 6061-T6 aluminium, hard anodised black, 9.4 mm (0.370 in) high, with laser-etched positioning markers so accessories go back in the same slot every time. 10/24 flat-head screws and M-LOK nuts are included.
