Geissele Automatics Picatinny Accessory Rail For M-Lok Handguards, 5 Slots

The Geissele Automatics Picatinny Accessory Rail for M-Lok handguards is a precision-engineered rail segment that bridges the gap between modern M-Lok mounting systems and standard Picatinny accessories. If you're running an AR-15 with an M-Lok handguard but need to mount lights, lasers, grips, or other gear designed for Picatinny rail, this 5-slot adapter gives you that flexibility without replacing your entire handguard. Geissele's commitment to precision machining means you're getting a rock-solid, mil-spec compatible platform that won't wobble or shift when your accessory is under load.

Built from 7075-T6 aluminum—the same material found in aircraft and high-end optics—this rail delivers exceptional strength-to-weight performance. The hardcoat-anodized finish provides corrosion resistance and durability in the field, whether you're shooting suppressed at a range, hunting in wet conditions, or training hard. The precision machining ensures exact Picatinny specifications, so your accessories seat flush and lock tight every time. Installation is straightforward: the rail mounts directly to your M-Lok handguard using standard M-Lok hardware (not included).

The 5-slot configuration offers a balanced compromise between accessory mounting real estate and handguard real estate, letting you position optics, lights, or supports exactly where you need them without over-cluttering your setup. Whether you're building a recce rifle, a carbine for night work, or a precision shooter with auxiliary gear, this adapter gives you the modularity M-Lok promised without the expense of a new handguard.
