The MK18 is the latest in the line of Geissele Super Modular rails and is specifically made to interface with the Arca-Swiss Quick Release System. This new handguard is based on the MK16 M-LOK Super Modular Rail, offering a small diameter and overall height creating a slim profile for competition shooters. 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. The MK18 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 16” long MK18 is 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.
