Geissele’s Super Modular MK4 M-LOK Rail is a perfect choice for lightweight AR15 builds. It features multiple M-LOK attachment points in the 3, 6, and 9 o’clock positions, as well as in the upper 45 quadrants to provide the user with virtually unlimited customization options. The abundance of M-LOK mounting points also dramatically reduces the rail’s weight, and also provides maximum venting to help the barrel cool off faster after prolonged firing. The Super Modular MK4 M-LOK Rail also utilizes Geissele’s proprietary 2.25” barrel nut, making installation simple and enhancing rigidity.
