Magpul Industries M-LOK Polymer Rail 3 Slots 1.6" Black

The Magpul Industries M-LOK Polymer Rail (MAG589-BLK) is a 3-slot Picatinny rail section purpose-built to mount on any M-LOK compatible handguard or forend. At just 1.6" long, it provides three fully usable Picatinny slots in a compact footprint, giving you a quick, low-cost way to add a light, switch, or other 1913-spec accessory to an otherwise slot-less M-LOK handguard.

Magpul molds this section from their lightweight reinforced polymer so it adds minimal weight to your rifle while standing up to hard use and recoil. The section locks into the M-LOK interface using cammed T-Nuts that you torque down with a simple hex driver, while integrated recoil/impact mitigation lugs keep the rail seated solidly under firing and rough handling. The matte black finish blends cleanly with most factory handguards.

Designed and Made in the USA, the MAG589-BLK is a straightforward drop-in solution for adding a short stretch of Picatinny real estate to any M-LOK-equipped platform. Whether you need a small mount point for a backup iron, a tape switch, or a light body, this 3-slot polymer rail section gives you that space without committing to a longer or heavier aluminum rail.
