Coming Soon! Super Modular Rail MK8 with M-LOK Technology

Coming soon! The Super Modular Rail MK8, featuring M-LOK technology, M-LOK is a modular locking accessory mounting system that is a direct attachment method for hard mounting accessories to a negative space mounting point. Designed by Magpul lndustries as an evolution of the MOE slot system used since 2007, the M-LOK system is being released as a free licensed platform to allow greater compatibility of accessories between all manufacturers.

History

In late 2007 Magpul Industries Corp developed the Masada Concept Rifle that featured a polymer hand guard with three elongated vent holes that acted as a negative mounting surface for accessory rails.

 These slots became one of the first “negative space” attachment systems that allowed the user to only put mounting rails where they were needed, as opposed to covering the entire surface with mounting rails, then covering those rails with panels. The system also allowed direct mounting of accessories, such as fore-grips and flashlights with no rail interface needed.

In 2008 the MOE hand guards for the common AR15/M16 firearms were released, bringing the same slot system, along with rails, flash light mounts, grips and other accessories to the mainstream.


In the years since the MOE slot system has been released, several million MOE slot compatible accessories have been produced. While initially introduced as a Magpul-specific system, several other companies over the years have built MOE slot compatible accessories.

The MOE system, while popular, was never officially released as an open standard, and the requirement to have access to the back side of the mounting surface limited its application. Additionally, depending on the accessory item, the spacing increments were not always small or uniform enough for desired placement.

These last characteristics made MOE slots and accessories less ideal to use with free-float hand guards which did not allow back side access to the mounting surface, and where small, standardized increments of accessory placement were desired. Rather than just documenting and publishing the existing MOE slot information and weld nut system, Magpul engineers used this opportunity to substantially improve the feature set of the MOE system.

The result is M-LOK.

M-LOK Features

The M-LOK system retains an elongated slot appearance, similar to MOE slots (with different dimensions). The new slot is larger, has squared sides, and the new system adds the following feature set, and additional information can be found by clicking here:

  • Direct Mount Capability
  • Recoil Mitigation Lugs
  • Intermediate Spacing Option
  • Multi-Directional Mounting
  • Optimized for Metal & Polymer Manufacturing
  • Cammed T-Nut
  • Backwards MOE Compatibility
