The Magpul M-Lok 9-Slot Aluminum Rail Section is a precision accessory rail designed for shooters who want flexibility in mounting lights, grips, and other Picatinny-spec gear directly to their M-Lok compatible handguards and forends. This 4.1" black aluminum rail works with any handguard or forend that features M-Lok slots, making it an essential modular upgrade for AR-15s, modern sporting rifles, and other platforms built around the M-Lok system. Whether you're setting up a duty rifle, a precision shooter's platform, or a home-defense carbine, this rail section lets you add capabilities exactly where you need them without replacing your entire handguard.
Machined from milspec-anodized aluminum, the rail is built tough enough for serious use while staying lightweight. The beveled ends reduce snagging on gear and clothing and eliminate the sharp corners that can catch on slings or your body during transitions. All mounting hardware needed to secure the rail directly to M-Lok T-nuts is included in the box, so you can install it right away. The integrated recoil and impact mitigation lugs help manage the force of accessory-mounted gear during firing, protecting both your rail and whatever you've attached to it.
This is genuine Magpul engineering—designed, tooled, and made in the USA to work seamlessly within the M-Lok ecosystem. At 4.1 inches, it's long enough to mount multiple 1913 Picatinny spec accessories in a compact, purposeful arrangement, without overcommitting your rail estate.
