Geissele Super Modular Rail MK18

Designed for Arca-Swiss Compatibility

The MK18 is the latest addition to Geissele’s Super Modular Rail lineup and is specifically engineered to interface with the Arca-Swiss Quick Release System. Its flat base features a 35mm “Arca-Style” form with a 45-degree dovetail, enabling quick and adjustable mounting along the rail.

Slim and Durable Design

• Compact Profile: Based on the MK16, the MK18 offers a small diameter and height for a slim competition-ready profile.
• Material: 3D precision machined from 7000 Series Aluminum for strength, rigidity, and lightweight performance.
• Barrel Nut Length: Geissele’s proprietary 2.25" long barrel nut ensures a straight and true platform along the entire rail.

Modularity and Customization

Utilizing Magpul’s M-LOK technology at the 3 major quadrants (left, right, and bottom) as well as the upper 45-degree positions, the MK18 allows unprecedented modularity for attaching accessories to suit individual needs.

Finish Options and Compatibility

The Geissele MK18 Super Modular Rail is available in durable Type 3 Hardcoat Anodized finishes, including Black or DDC, and is compatible with mil-spec AR15 pattern rifles.
