Geissele Automatics Super Modular Rail MK15 14.50" M-LOK Handguard - Black

The Geissele Automatics Super Modular Rail MK15 is a free-float handguard engineered to replace the factory rail on HK416 and MR556 weapon platforms. Machined from 6061-T6 aluminum and finished in Type III hardcoat anodized black, the MK15 is built to meet military specifications for hard-use duty carbine applications.

Measuring 14.50" in length, the rail provides M-LOK mounting slots at the 3, 6, and 9 o'clock positions for attaching lights, lasers, vertical grips, and other accessories, while preserving a full-length Picatinny top rail for optics and back-up iron sights. The MK15 utilizes the factory HK barrel nut and hardware, so it installs cleanly on a compatible HK-pattern upper without proprietary mounting components.

Whether you are upgrading a duty carbine, refining a clone-correct HK416, or building a precision MR556, the Super Modular Rail MK15 delivers the strength, modularity, and fit-and-finish Geissele Automatics is known for.
