The Magpul MAG582-BLK M-LOK 7 Slot aluminum rail section gives you a compact way to mount 1913 Picatinny-spec accessories on any M-LOK compatible handguard or forend. Whether you're running a tactical light, vertical grip, or other rail-mounted gear, this 3.3" rail bridges the gap between your modular setup and standard optics-rail components. It's machined from milspec-anodized aluminum and built tough enough for duty and competition use.
Installation is straightforward: the rail mounts directly to M-LOK T-nuts on aluminum or polymer handguards, and all hardware comes included. The design includes beveled ends to keep snagging out of the picture and eliminate the sharp corners that can snag gloves or gear during transitions. Built-in recoil and impact mitigation lugs help absorb the harsh stuff without wearing your rail down over time.
Made in the USA, this Magpul rail section is engineered to the same standards as the rest of their modular ecosystem. If you've already committed to M-LOK for weight savings and simplicity, this aluminum rail section rounds out your accessory mounting options without the bulk of a full-length Picatinny rail.
| Brand | Magpul |
| Model | MAG582-BLK |
| Material | Milspec-anodized aluminum |
| Slot Count | 7 |
| Overall Length | 3.3" |
| Color | Black |
| Compatibility | M-LOK compatible handguards and forends |
| Accessory Standard | 1913 Picatinny spec |
| Country of Origin | Made in U.S.A. |
The Magpul MAG582-BLK mounts directly to M-LOK T-nuts on any M-LOK compatible handguard or forend, whether it's aluminum or polymer. It connects via the same T-nut system that all M-LOK accessories use.
Any standard 1913 Picatinny-spec accessory will work—lights, vertical grips, bipods, backup sights, laser modules, and more. If it has Picatinny slots on the bottom, it'll clamp to this rail.
Yes. All hardware necessary to attach the rail directly to M-LOK slots is included in the package.
Aluminum offers superior rigidity and durability under recoil, making it the better choice if you're mounting heavier optics or running high-recoil calibers. The milspec anodize finish also resists corrosion better than polymer in wet or harsh conditions.
