The Geissele MK14 Super Modular Rail tactical AR-15 handguard has a slim cross-section that makes it is ideal for shooters who use rail covers and/or a vertical grip - and who also employ the thumb-over-the-bore support hand grasp. Similar to their MK13 SMR, the Geissele MK14 delivers acres of real estate for mounting accessories, with M-LOK slots running the handguard's full length at the 3, 6, and 9 o'clock positions. The MK14 Super Modular Rail also sports an uninterrupted Picatinny rail running the full length of the top. Geissele even thoughtfully includes sockets for QD pushbutton sling swivels at the 11 and 1 o'clock positions at the rear. Strong & l Mfg: Geissele Automatics
