AB Arms Polymer M-LOK Picatinny Rail, 4-Slot

The AB Arms Polymer M-LOK Picatinny Rail (brand part no. ABAMR4) is a lightweight, 4-slot Picatinny section built for M-LOK handguards, using a high-heat-resistant polymer that stays cooler to the touch than an aluminum rail in the same spot. It ships with M-LOK T-nuts and 10-24 x 1/2-inch flathead screws measuring 1.875 inches long, so installation does not require sourcing separate hardware. It is a simple, budget-friendly way to add a short Picatinny mounting point to any M-LOK-compatible handguard.
