The Magpul M-LOK Poly Rail Section 5 Slots is a lightweight, cost-effective polymer rail accessory designed to expand mounting options on M-LOK equipped platforms. Injection-molded from Magpul's proprietary reinforced composite, this rail section provides operators and shooters with a rugged, weight-conscious solution for attaching 1913 Picatinny spec rail-mounted accessories—lights, vertical grips, and other tactical gear—directly to existing M-LOK slot patterns.
At just 0.13 lbs, this five-slot section maintains the modular philosophy of M-LOK systems without adding unnecessary weight to your handguard or furniture. The reinforced polymer construction delivers enhanced strength and durability compared to standard offerings, while beveled ends eliminate sharp corners and snagging points—critical design features on duty carbines and carbines used in dynamic environments. All hardware required for direct attachment to M-LOK slots on either aluminum or polymer handguards is included. The 4.25-inch length provides flexible rail real estate for single or dual accessory mounting configurations.
This rail section suits patrol officers, tactical shooters, and AR platform builders seeking economical rail expansion without the premium cost of full-length aluminum alternatives. Law enforcement using modern rifle platforms with M-LOK handguards, as well as recreational shooters setting up training or competition carbines, benefit from modular, mission-configurable lighting and support systems. It serves as an economical alternative for those who need selective rail placement rather than continuous coverage.
M-LOK has become the dominant mounting standard across modern tactical platforms, offering superior weight and ergonomic distribution compared to fixed rail systems. Magpul's polymer rail sections deliver the integration flexibility of aluminum at reduced cost and weight, making them a practical choice for duty builds, training setups, and budget-conscious configurations where strategic accessory mounting suffices.
