Geissele’s Super Modular Rail (SMR) MK14 M-LOK handguard is the latest entry to the Geissele line-up of Super Modular Rails. The new handguard design offers a smaller diameter and overall height to create a slimmer package. Included with the MK14 Super Modular Rail is an updated version of the proven Geissele Barrel Nut design, not only providing ease of installation but also superior rigidity. The long surface contact of the 2.25″ barrel nut interfaces with the receiver, creating a platform that can be trusted to be straight and true the entire length of the free float rail. The MK14 is precision machined using 6061-T6 aluminum due to its strong, rigid and lightweight properties. Utilizing Magpul’s M-LOK technology in the 3, 6, and 9 o’clock positions allows the end user full customization and modularity of their rifle to securely mount lights, bipods and other firearm accessories. The Geissele MK14 Super Modular rail is Type 3 Hardcoat Anodized. Requires a Geissele barrel nut wrench for installation (sold separately).
