From the manufacturer
Geissele Super Modular Rail MK18 M-Lok Arca-Swiss 16in Desert Dirt Color. 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 Geisseles proprietary 2.25in 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 16in long MK18 is 3D precision machined using 6061-T6 Aluminum due to its strong rigid and lightweight properties. Utilizing Magpuls 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 Geisseles DDC finish. The Geissele Super Modular Rail MK18 is compatible with AR15 pattern rifles.
