Geissele’s Super Modular MK16 Rail is easy to install and allows for virtually unlimited customization options. It attaches to an AR-15’s upper receiver with an enhanced version of Geissele’s proven Barrel Nut, making installation and maintenance easy, as well as providing excellent rigidity. The MK16 is outfitted with anti-rotation tabs and set screws, ensuring the rail will not pivot even under extreme conditions. In addition, the MK16 features M-LOK mounting locations in the 3 o’clock, 6 o’clock, and 9 o’clock positions, as well as in the upper and lower 45° positions for maximum customization, and a 12 o’clock picatinny rail accommodates the installation of optics and other picatinny-based accessories.
