Overview

The Geissele Automatics Super Modular Rail (SMR) MK16 is a 15-inch free-float handguard engineered for the AR-15 platform. Machined from 7000-series aluminum and finished in a Type 3 hardcoat anodized black, this rail features a 1.26-inch inner diameter and a 1.59-inch outer diameter. The profile stands 2.39 inches tall, providing a robust surface for handling and accessory mounting. The MK16 utilizes an M-LOK attachment system along the sides and bottom, paired with a full-length Picatinny top rail. The design incorporates an updated barrel nut system with anti-rotation tabs and set-screws to ensure superior rigidity and zero retention. At 15.6 ounces (17.1 ounces with the included barrel nut), the rail is designed for durability and consistency, leaving the barrel free-floated to eliminate pressure points.
