Description
The Geissele Super Modular Rail MK18 is engineered for precision-focused and competitive shooters, delivering a lightweight, rigid platform optimized for modern match applications. Designed to integrate directly with the Arca-Swiss Quick Release System, this newest addition to Geissele’s rail lineup builds on the proven MK16 M-LOK profile, retaining its compact diameter and low height to create an exceptionally streamlined handguard.
Its flat underside incorporates a 35mm Arca-style interface with a 45-degree dovetail, allowing shooters to quickly clamp the rifle to Arca-Swiss compatible mounts and position it anywhere along the rail. Stability is ensured through Geissele’s signature 2.25-inch barrel nut, providing a precise, aligned foundation for the entire free-float assembly.
Machined from 7000-series aluminum for strength and weight reduction, the 16.5″ MK18 offers extensive modularity through M-LOK slots at the 3, 6, and 9 o’clock positions, plus upper 45° surfaces. Each rail receives a durable Type III hardcoat anodized finish in Black or DDC.
Compatible with mil-spec AR-15 platforms.
Weight with barrel nut: 18.4 oz.
