Showing no signs of slowing down, Magpul continues their run of product announcements with the unveiling of their M-LOK rail attachment system, brand new for 2014. A video which offers a closer look at this system can be seen below.

Magpul’s M-LOK system provides a simple way (direct attachment) to hard mount accessories to rails. It is the next step in the design evolution that began with the MOE slot system. The M-LOK, or Modular Lock system, features a longer slot and squared sides. Using M-LOK, accessories can be mounted directly from the front face of the slot. The M-LOK includes recoil mitigation lugs on all four sides which provide support to accessories.

This system also features a cammed T-Nut. According to the product release, “Simply adjust the gap between the T-Nut and accessory to match the thickness of the mounting surface, align the T-Nuts with the slot, and insert in the desired location. An initial 1⁄4 to 1⁄2 turn of the screw for each T-Nut rotates the nut into engagement and then you may tighten normally.”

An open-source platform, M-LOK is compatible with accessories from all manufacturers. According to Soldier Systems, a list of participating manufacturers includes ArmaLite, Troy, Geissele, Diamondhead, ARES, Primary Weapons System, JP Enterprises and many more.
