Magpul M-LOK Rail Section Polymer 11 Slot Picatinny

The Magpul M-LOK Rail Section Polymer with 11 slots is a reinforced polymer Picatinny rail segment designed to add a mounting area to any M-LOK-compatible handguard or surface. It addresses the shooter who needs an attachment point for Picatinny-interface accessories — secondary optic, torch, aiming device, vertical grip — without giving up the weight savings of the M-LOK system across the rest of the platform.

The reinforced composite polymer keeps the component weight to a minimum: on an already lightweight handguard, adding a steel or aluminium section where polymer is sufficient means adding unnecessary weight to the rifle. The material choice is therefore a deliberate trade-off: the section handles everyday accessories such as torches and aiming devices without issue, but anyone planning to mount heavy components or items subject to repeated strong lateral loads should consider the aluminium version in the same product family.

The 11 Picatinny slots provide enough longitudinal adjustment to find the optimal position for any accessory, and the standard MIL-STD-1913 profile ensures compatibility with every quick-detach or screw-mount attachment on the market. It attaches directly to the M-LOK slots of the handguard using the hardware specified by the system, with no intermediate adapters required.

Key points

• 11 MIL-STD-1913 Picatinny slots allow precise accessory placement without being locked to a single position.
• Reinforced composite polymer adds mounting capability without adding weight where a metal profile is not needed.
• Direct compatibility with any M-LOK handguard: no intermediate adapters, installation with standard system hardware.
• Modular solution: fits only where needed, leaving adjacent M-LOK slots free for other accessories or to maintain the handguard's slim profile.
