Geissele Automatics Picatinny Accessory Rail For M-Lok Handguards, 7 Slots

If you've built an AR with an M-LOK handguard and want to mount lights, lasers, grips, or other tactical accessories, a Geissele Automatics Picatinny Accessory Rail for M-LOK Handguards gives you a solid, standard-spec way to do it. This 7-slot rail segment bolts directly to your M-LOK slots, converting that area into genuine Picatinny rail real estate so you can use any mil-spec accessory without adapters or workarounds. Geissele machined these from 7075-T6 aluminum and finished them with hardcoat anodizing—the same precision and durability you'd expect from a company known for triggers and upper-receiver components. Whether you're setting up a duty rifle, a precision build, or a recce gun, this rail bridges the M-LOK/Picatinny gap cleanly.

The 7-slot length gives you enough mounting area for multiple accessories or one larger optic mount without eating up your entire handguard. M-LOK's one-piece slot design makes attachment straightforward and repeatable—just align the rail, thread the bolts, and you're ready to mount whatever comes next. The hardcoat anodize holds up to hard use and won't rattle or shift under recoil or rough handling.

Geissele's attention to machining tolerances means this rail will fit tight and stay put. If you're running an M-LOK setup and want the simplicity and accessory ecosystem of Picatinny rail, this segment solves the problem without compromise.
