Geissele MK14 Super Modular Rail M-LOK – Multiple Options


Available Options:

Geissele MK14 Super Modular Rail M-LOK

The Geissele MK14 Super Modular Rail is the latest model into the Super Modular Rail family. The new design offers a smaller diameter and overall height for a slimmer package. It has an updated version of the proven Geissele Barrel Nut design, not only providing ease of installation but 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 rail is precision machined from 6061-T6 Aluminum making it strong, rigid and lightweight.

Utilizing Magpul’s M-LOK technology in the 3, 6, and 9 o’clock positions allow 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 finished in a durable and long lasting Type 3 Hardcoat Anodized available in either Black or Geissele’s DDC finish.
