Description

Geissele MK18 Super Modular Rail M-LOK

The Geissele MK18 Super Modular Rail was specifically created to interface with the Arca Swiss Quick Release System. It is based on the MK16 M-LOK Super Modular Rail, offering a small diameter and overall height creating a slim profile for competition use. The flat base of the MK18 features an “Arca Style” 35mm wide form with a 45 degree dovetail, that allows quick mounting to an Arca Swiss Quick Release mounting base, sliding into any position along the rail. It features Geissele’s proprietary 2.25″ long barrel nut that interfaces with the receiver and creates a platform that can be trusted to be straight and true the entire length of the free float rail. The rail is 16″ in length and 3D precision machined using 6061-T6 aluminum due to its strong, rigid and lightweight properties.

Utilizing Magpul’s M-LOK technology at the major 3 quadrants (left, right and bottom), as well as the upper 45’s gives the MK18 unprecedented modularity and ability to be customized. The MK18 Super Modular rail is finished in a durable and long lasting Type 3 Hardcoat Anodize available in either Black or Geissele’s DDC finish.

The Geissele Super Modular Rail MK18 is compatible with mil-spec AR15 pattern rifles.
