Overview

The Geissele Automatics MK4 Super Modular Rail is a 15-inch, ultra-lightweight free-float handguard designed for the AR-15 platform. Finished in Desert Dirt Color (DDC), the rail features integrated M1913 Picatinny rail sections at the 3, 6, and 9 o'clock positions for optics or accessories. M-LOK attachment points are located along the 3, 6, and 9 o'clock positions and the upper 45-degree quadrants.
