Product Description

The Geissele Automatics MK8 Super Modular Rail (SMR) is a premium free-float AR-platform handguard designed to deliver a strong, rigid mounting solution with extensive modularity. This 10.5-inch rail features M-LOK attachment points at the 3, 6, and 9 o’clock positions as well as the upper 45° quadrants, giving you broad flexibility to mount lights, lasers, grips, and other accessories. Venting in the lower 45° quadrants enhances airflow for improved heat dissipation while helping keep the rail streamlined. Finished in Geissele’s Desert Dirt Color (DDC), the MK8 also incorporates Geissele’s proprietary 2.25-inch barrel nut interface for a secure, true-running platform.
