Magpul MAG591-BLK M-Lok 7-Slot Polymer Rail, 3.3" Black$11.09
Availability: In Stock
The Magpul MAG593-BLK M-LOK 11-slot polymer rail is a straightforward, no-frills solution for mounting tactical accessories to any M-LOK compatible handguard or forend. Whether you're running a modern AR, precision rifle, or shotgun with M-LOK slots, this 4.9-inch rail section lets you attach standard 1913 Picatinny-spec gear—weapon lights, vertical grips, laser modules, or other rail-mounted tools—to your setup without the cost and weight of full-length aluminum systems.
Built from Magpul's injection-molded reinforced polymer composite, this rail strikes a practical balance between durability and weight. The material is tough enough for field use, yet won't add unnecessary heft to your gun. You get beveled ends that eliminate snagging points and sharp edges, a detail that matters whether you're working in the dark, moving quickly, or simply stowing your rifle in a bag. The rail also includes recoil and impact mitigation lugs to absorb shock—something polymer rails should do but not all do well.
All mounting hardware needed to attach directly to M-LOK T-nuts on aluminum or polymer handguards comes in the box, so you're ready to start configuring right out of the package. Made in the USA, this is the kind of accessory that turns a basic rail system into a functional fighting platform without forcing you to redesign your entire setup.

This rail mounts to any M-LOK compatible handguard or forend, whether aluminum or polymer. If your rail system has M-LOK slots and uses standard T-nuts, this rail will attach directly. Check your handguard documentation to confirm M-LOK compatibility.
Any accessory designed for standard 1913 Picatinny rails will work—that includes tactical lights, vertical grips, laser modules, backup sights, and rail-mounted braces or adapters. The 11 slots give you multiple positions along the 4.9-inch length.
Yes. All fasteners and hardware needed to mount this rail directly to M-LOK T-nuts come in the box. You won't need to source additional hardware separately.
Magpul's reinforced polymer composite is designed for field conditions and includes recoil/impact mitigation lugs to handle shock. The beveled ends also reduce damage from contact. For most shooters, this is a solid middle ground between cost and durability compared to full aluminum systems.
