Geissele Automatics Super Modular Rail MK4 9.30" M-LOK AR-15 Handguard - Desert Dirt

The Geissele Automatics Super Modular Rail MK4 is an ultra-rugged, ultra-lightweight free-float handguard purpose-built for the MK4 platform, the M4 carbine, and all mil-spec AR-15 variants. This 9.30" rail is constructed from aluminum and finished in Geissele's signature Desert Dirt Color (DDC) with a Type III hardcoat anodized finish for long-lasting wear and corrosion resistance.

The MK4 uses Magpul M-LOK mounting slots at the 3, 6, and 9 o'clock positions as well as the upper 45-degree quadrants, allowing the user to attach lights, lasers, vertical grips, and other accessories directly to the handguard. Integrated M1913 Picatinny rail sections at the top and bottom provide a continuous, optics-ready mounting surface. The rail is fully free-floating to maximize accuracy by eliminating contact with the barrel, and a barrel nut is included for installation.

Designed and manufactured by Geissele Automatics, the Super Modular Rail MK4 is part of Geissele's premium lineup of purpose-built AR handguards, prized by shooters for their light weight, modularity, and battle-proven construction.
