The Magpul M-LOK Aluminum Rail Section, 7-Slot is an aluminium Picatinny rail section that mounts directly into any M-LOK handguard slot.
Add a length of Picatinny rail exactly where you need it — the direct-mount aluminium way to run rail accessories on an M-LOK handguard.
The Magpul M-LOK Aluminum Rail Section, 7-Slot (MAG582) bolts straight to any M-LOK slot and gives you seven slots of MIL-STD-1913 Picatinny rail for lights, lasers, older mounts or a hand stop. Machined from hard-anodised aluminium for a rock-solid, low-profile platform, it uses the M-LOK cam-lock system for a secure, repeatable mount and ships with the hardware you need to fit it.
Fits any M-LOK-compatible handguard or forend, and provides MIL-STD-1913 Picatinny rail for rail-mount accessories. Handguards that are Picatinny-only or use a different slot standard will not take it, so check what your forend actually is before ordering. The M-LOK mounting hardware is supplied — fit it where the accessory needs to sit, torque it down and re-check after the first range trip. The same section is also made in three-slot, five-slot and nine-slot lengths if you need less rail or more.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.
You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging.

It fits any M-LOK-compatible handguard or forend, so the first thing to check is that your forend is genuinely M-LOK rather than Picatinny-only or a different slot standard. A seven-slot section needs a correspondingly long clear run of M-LOK slots, so measure the space before ordering. If your handguard is already Picatinny along its full length, you don't need this at all.
It converts M-LOK slots into MIL-STD-1913 Picatinny rail, so accessories built for Picatinny will mount on an M-LOK forend. That covers lights, lasers, older mounts and a hand stop — anything with a rail clamp rather than a direct M-LOK footprint. It uses the M-LOK cam-lock system, which draws the section tight inside the slot for a secure, repeatable mount.
Seven slots gives a long mounting run, which suits a longer rail-clamp mount or two accessories sharing one section. The same hard-anodized aluminium section is also offered in <a href="/products/magpul-m-lok-aluminum-rail-section-3-slot">three-slot</a>, <a href="/products/magpul-m-lok-aluminum-rail-section-5-slot">five-slot</a> and <a href="/products/magpul-m-lok-aluminum-rail-section-9-slot">nine-slot</a> lengths if you need less rail or more. Our <a href="/blogs/buying-guides/m-lok-vs-picatinny-mounting-guide">M-LOK vs Picatinny guide</a> explains the two standards, and you can see what else direct-mounts in <a href="/collections/m-lok-accessories">M-LOK Accessories</a>.
Yes — the M-LOK mounting hardware is supplied, so you position the section where the accessories need to sit and torque it down. There are no permanent changes to the handguard and nothing gunsmith-level about it. It is worth re-checking the fasteners after the first range trip, as with any newly fitted rail hardware.
