Versatile and innovative, Geissele's MK4 DDC Super Modular Rail is a perfect addition to any AR-platform. It features a full length picatinny rail with more than enough space for optics, iron sights, and clip-on night vision/thermal devices. Additional forward-mounted picatinny rail segments are located in the 3, 6, and 9 o'clock positions, and numerous M-LOK attachment points towards the rear gives the user the user virtually unlimited customization options in terms of tactical lights, lasers, fore-grips, and other accessories. The lower 45° quadrants feature ample venting to help cool a hot barrel after extended shooting sessions, and also cut down on unnecessary weight. In addition, the MK4 DDC Super Modular Rail is outfitted with Geissele's proprietary 2.25" barrel nut to increase the surface contact where the rail interfaces with the receiver. This increases accuracy and zero repeatability during disassembly/reassembly.
