Geissele Automatics MK14 Super Mod Desert Dirt 10.5″ MLOK

Geissele MK14 Features

The MK14 design maintains a slim profile while maximizing strength, providing plenty of real estate for accessories without unnecessary bulk. Its M-LOK slots at 3, 6, and 9 o’clock, along with a full-length Picatinny rail, allow for full customization of lights, grips, and optics. The 10.5″ length is ideal for short-barreled rifles (SBRs) or pistol builds, offering the balance of compact size and modular utility.

This rail is fully compatible with low-profile gas blocks and allows for ample ventilation to aid barrel cooling under sustained fire. The included proprietary barrel nut ensures tight lock-up and precision alignment, though a barrel nut wrench is no longer included. Finished in Geissele’s signature DDC tone, it pairs perfectly with other Geissele components for a cohesive and battle-ready setup.
