Magpul M-LOK Rail Section Polymer 5 Slot

The Magpul M-LOK Rail Section Polymer 5 Slot is a reinforced polymer Picatinny rail section designed to add standard-accessory attachment points to any platform with an M-LOK interface. It is the straightforward solution for mounting a light, laser, or bipod on a section of a handguard that has no native rail, without touching the weapon's hardware.

The reinforced composite polymer keeps weight down compared to a machined aluminium section: anyone carrying a rifle for hours, whether hunting or on duty, will notice the difference in balance. The trade-off is clear: the polymer section handles the stress of ordinary recoil and holds common accessories securely, but it is not the right choice for heavy accessories or high-recoil calibres, where an aluminium section provides greater structural rigidity.

Installation uses the handguard's M-LOK system directly: the bolts slot in and lock the section in place without any special tools. The resulting 5 Picatinny slots allow the accessory to be positioned with fore-and-aft adjustment, so the optimal balance point can be found without being locked into a fixed position.

Key points

• Adds 5 Picatinny slots to any M-LOK handguard with no permanent modifications to the weapon.
• Reinforced polymer reduces weight compared to the aluminium equivalent, with less impact on weapon balance.
• Fore-and-aft adjustment along the rail allows accessory position to be fine-tuned after mounting.
• Compatible with the full range of standard Picatinny rail accessories: lights, lasers, bipods, grips.
• Direct mounting on M-LOK slots with no additional adapters required.
