Low Cost Polymer M-LOK Rail Section with QD Sling Mount

This polymer M-LOK rail section with aluminum QD sling mount gives you tons of options for adding accessories to your M-LOK handguard. The lightweight rail section offers a secure mounting surface for bipods, foregrips, and weapon lights that attach to picatinny rails. The QD sling mount socket accepts standard quick detach swivels with 90 degree rotation stops.

If you’re planning to mount accessories that need extra strength, check out this kit with an aluminum rail section instead, plus color-matched Cerakote finishes.
